Lassonde Institute expands partnerships across U of T researchers to increase global industry reach

Institute’s new and extended multidisciplinary mandate provides national leadership for advanced mining research and innovation

In U of T’s Mining, Water and Environment Facility, Tara Colenbrander Nelson, field researcher, analyzes samples collected from four Canadian mine sites. This unique industry partnership is developing new tools that will enable the mining industry to better monitor, manage and reduce environmental impacts associated with sulphur compounds in their wastewaters.

The Lassonde Institute is expanding its mandate to increase research collaborations across U of T and the Faculty of Applied Science & Engineering. The new direction reflects the interdisciplinary nature of the resource sector today and aims to address complex industry challenges through world-leading research and innovation.

The Institute, now positioned to represent the depth of U of T mining researchers through a collaborative and streamlined approach, expands industry’s ability to overcome and resolve problems while maximizing impact for our society, economy, and planet. Greater research collaborations accelerate new knowledge and innovations for improving worker health and safety and mitigating environmental impacts around water and energy. Increased multidisciplinary partnerships also help the sector’s continued decarbonization work while increasing productivity, as well as recovery and recycling efforts, and automation and digital technologies integration.

“As a Faculty-wide institute, we span the entire breadth of the mining lifecycle with expertise from engineering, earth and environmental sciences, public policy, and beyond,” says Lesley Warren, Director, Lassonde Institute. “We are growing the innovation ecosystem through our transdisciplinary work and expediting innovations for companies by reimagining what mining research can achieve for industry.”

Both increasing resource demands needed to build a more sustainable future and the urgent concerns around societal and environmental impacts are dramatically reshaping the resource sector. To lead and develop leading-edge, sustainable technologies, Canadian and multinational companies need an expanded innovation ecosystem to tackle complex challenges and secure success for our communities and planet.

“For Canada to be successful and for companies to meet global demands, we must lead technology development and relevant knowledge innovations. Our industry requires continuing efforts and a commitment to sustainable solutions,” says Ian Pearce, former CEO, Xstrata Nickel. “If our innovation ecosystem is incomplete or fails to maximize university research and development, our sector is at risk of missing commercial, economic, and environmental successes.”

The Lassonde Institute is pivoting to address current needs as well as emerging challenges associated with complex sustainable development efforts. A crosscutting Institute with access to University-wide experts and researchers represents a greater commitment to future discovery and sustaining efforts to expand research partnerships.

“This is an exciting new phase in the evolution of the Lassonde Institute,” says Christopher Yip, Dean of the Faculty of Applied Science & Engineering. “By bringing U of T researchers together and expanding our global partnerships, we are generating concrete solutions to many of the multi-faceted challenges facing the industry today, and further solidify Toronto and Canada as a mining innovation leader.”

Bacterial mutants and hydrogen peroxide may be keys to reclaiming value from tailings ponds clean-up

By Alexandra Lopez-Pacheco (Article was originally published in CIM Magazine here. )

While the technology could offset the cost of remediating the tailings ponds, according to the researchers the process to extract nickel from pyrrhotite is complex. A combination of bacterial mutants and hydrogen peroxide may be key to not only remove reactive material from the tailings and leave behind a benign product, but to extract billions of dollars worth of nickel and other metals.

MSE Professor, Erin Bobicki, awarded NSERC Strategic Partnerships Grant

Professor Erin Bobicki is among five U of T Engineering researchers awarded NSERC Strategic  Partnerships Grant. Bobicki ‘s project will investigate the potential viability of new strategies on “Combining CO2 storage with mineral processing”: certain mineral processing wastes have the capacity to store CO2 in mineral form. CO2 also has the potential to be used as a novel reagent to enhance the separation of minerals and stabilize waste materials. This presents an opportunity to both store CO2 captured from flue gases or other industrial sources and enhance the extraction of metals from ores. Depending on the regulatory framework or incentives around CO2 sequestration, these processes could add new revenue streams for mineral processing companies.

In total, the program invested more than $2.6 million in U of T Engineering and more than $3.8 million across the entire University.

From between a rock and a hard place (for women) to an equitable and more profitable place for all: Why gender diversity in mining is vital to the strength and future of the industry

Mining’s “not so secret” secret
It is an accepted industry-wide truth: mining has a gender diversity issue.

The industry lags behind most other sectors in tackling this systemic problem with recent statistics showing women represent only 16 per cent of the Canadian mining workforce compared to 48 per cent of the overall Canadian workforce.

The challenge of building a gender-balanced workforce stretches from site to the boardroom. According to a 2016 PWC study, the mining industry has the lowest representation of women on boards of any other sector, including oil and gas, technology, and manufacturing. Additionally, out of the top 500 globally listed mining companies, only 8 per cent of executive officers in company leadership roles are women (

Whiffs of change
Between 2018 and 2019, mining companies such as Agnico Eagle, Barrick Gold and Newmont Goldcorp have started making strides in narrowing the gender gap. For example, in 2018, Agnico Eagle became an active participant in The International Women in Resources Mentorship Program (IWRMP), a collaboration between International Women in Mining, Women in Mining Canada and Metisphere. IWRMP connects senior global female mining leaders with mentees in a variety of occupations across the entire mining cycle. In early 2019 Barrick Gold began a certification process for gender equality at its Pueblo Viejo mine in the Dominican Republic. Newmont Goldcorp’s CEO, Gary Goldberg, pledged support for Paradigm for Parity, a global corporate initiative to achieve gender parity by 2030 and holding true to that commitment, Newmont most recently appointed three female executives after their merger with Goldcorp.  These are all important steps, however for systemic transformative change, these types of initiatives need to be happening industry wide and with clear accelerated targets to achieve parity and inclusivity.

It just makes business sense
It has been shown time and again that companies prioritizing diversity and inclusivity are 21 per cent more likely to deliver “above-average profitability” and greater long-term value with the key correlation linked to gender diverse executive teams (McKinsey).  Why might this be so? Mining companies prioritizing gender parity as a strategic objective possess a diversity of ideas, experiences, cognitive frameworks and expertise that becomes an advantage in a competitive market, e.g.  facing volatile commodity prices.  A diverse workforce is more adaptable and productive; delivering higher performance for shareholders and stakeholders (McKinsey).

Deloitte also revealed through their 2018 Global Human Capital Trends survey of mining companies, that diversity is correlated “to better performance and corporate decision-making” indicating that leaders today must prioritize corporate diversity and inclusion imperatives.

 CEO and President of Teck, Don Lindsay states, “An inclusive and diverse workforce can lead to improved health and safety performance, increased innovation and productivity, and better decision-making.”

Studies have shown that greater diversity at a company can lead to better financial performance, especially when seen at the board and senior management level (Shecter, Barbara, What’s a woman on the board worth to stock investors? About 300 bps, according to CIBC study. Financial Post, 2017). Underscoring what inclusivity delivers for better margins, a 2016 PWC study found a higher average profit margin overall (23 per cent) for mining companies with mixed gender boards, compared to the average net profit margin for the top 100 mining companies (20 per cent).

Building the Diversity Pipeline: Recruitment, retention and promotion
While the business case is clear: women in leadership is good for business – the challenge of retention reflected by the extremely  high attrition rate of mid-career female talent is a critical issue across the industry.

There have been great efforts by educational institutions like the Department of Civil and Mineral (our graduating class was 35 per cent female in 2019) and other initiatives like Vale’s Voisey’s Bay Underground Training Program (seeing 4 females of 10 incoming trainees) to attract females to the industry. However, even with increased female recruitment focus, systemic corporate barriers persist stifling women throughout the duration of their career and resulting in a ‘leaky pipeline’. This leak has been highlighted most recently through the #MeTooMining movement where  female mining professionals have come forward to voice their negative experiences on mine sites, in boardrooms and throughout the industry as well as their reasons for leaving the sector all together.

This pain point is an especially important one for an industry that requires maximum efficiency, resiliency and adaptability in order to survive and thrive. The loss of experience, competencies and decision-making skills residing in these women must be addressed with initiatives to tackle biased corporate culture.

Women face unique challenges in mining compared to their male counterparts, as a study concluded by Women in Mining Canada (Women in Mining Canada, Ramp-Up: A Study on the Status of Women in Canada’s Mining and Exploration Sector (Women in Mining Canada, February 2010). The study cited: work culture, lack of mentors, perception of their skills and work-life conflicts as some of the key barriers to female career advancement. In particular, fly-in fly-out mine sites were of concern for family planning and other life commitments the study found.

Where to start? Looking at the percentage of women at each phase of the career cycle is a productive and meaningful way for mining companies to measure the health of their workforce and identify where barriers and biases occur. Monitoring imbalances in gender pay gaps, gender-bias performance metrics, the ratio of eligible women versus promotion rates of women, or their odds of advancement compared to their male colleagues, are all ways mining companies can ensure their business operations are fully supporting and thus retaining women in the workplace.

Change comes from the top down
Transforming a culture requires commitment across an entire line of business; but mining company CEO’s dedicating efforts to this inclusivity imperative see the greatest results. Building a culture of inclusivity requires the active endorsement, sponsorship and amendment of business objectives by senior leadership.  Top executives must be the agent of change to reform the power structure and dissuade systematic unconscious bias.  Without this top-down culture shift, on-site employees will never substantively engage, and transformation will not take place. For this change, and its associated boost to company profits to happen in our lifetime, rather than at the current glacial rate of change, we need more women on boards and in leadership positions now.

 “Companies should require, not ask that executives promote, recruit and include women,” stated Cynthia Carrol the former CEO of Anglo America (2007-2013).

These concerns are gaining more traction with top mining leadership who are making both the ethical and business case for a dramatic culture shift.

Andrew Mackenzie, CEO, BHP says this about the gender parity goal at their Annual Meeting, “It will demand that we question our own biases when we make decisions, that we make our workplaces more flexible and that we challenge dated stereotypes about jobs in the resources industry.” Mr. Mackenzie recently said in an interview with the Sydney Herald, “It is about tapping “the best brains in the planet”, Mackenzie says, including younger people “who are at their most productive, their most inspirational, their most quick-thinking, their most quick-witted – we need to be attractive to them by having a modern approach to sexuality and race and inclusion. When they get here there should be absolutely no discrimination, and a sense that they can flourish.”

There had been unconscious bias in the industry and that women had been disadvantaged. In the company’s “most inclusive and diverse sites” performance is 15 per cent higher.

Around the world, countries are taking notice of the sizable deficit of female representation on boards. Though not strictly focusing on mining companies, the emphasis on gender parity through legislation associated with mandatory quotas or comply-explain regimes is sparking much debate.

While quotas can be helpful to provide measurable targets, there must be meaningful change for gender parity to take hold and transform a business. Women’s qualifications must hold equal weight to their male counterparts. The persistence of the ‘old boys network’, must make way for equitable appointments based on merits. With only 16 per cent representation in the overall workforce, women’s networks are limited, and male champions are needed to create dial-moving solutions.

The Lassonde Institute of Mining

As men, early in our career or later on in our career, we need to take every opportunity to come alongside our female colleges and support and advocate for them. We need to listen and champion for their efforts and realize it is everyone’s responsibility to make this industry welcoming to all. Having women in this sector makes us smarter and more resilient for a future where vital resources are critical.
Ian Pearce (Chair of the Board, New Gold; Director, Nexa Resources; Vice Chair, Outotec and Chair, MineSense Technologies).

Ian Pearce, an active industry advisor and champion for the Lassonde Institute, works alongside an all-women leadership team and first-ever woman director, Professor Lesley Warren, to develop a new vision for the 20-year old Institute.

Gender parity is not just seen at the L/I leadership level, but also in our top research pool of principal investigators. Over 50% of our L/I principle investigators are women. This feat, the likes of which other mining programs and institutes have not yet achieved, has been made possible by the catalyzing efforts of Dean Emerita Cristina Amon of the Faculty of Applied Science and Engineering at the University of Toronto. Her persistent championing efforts towards diversity, inclusivity and parity within the Faculty additionally supported by Department of Civil & Mineral Engineering’s chair, Professor Brent Sleep, have made this positive change possible at the Lassonde Institute.

The future of mining depends on diversity in mining
A diverse mining industry will mean a workforce that is flexible, adaptable and well prepared to tackle uncertainty. Canada’s mining sector could and should be global leaders in driving this transformative change. The facts tell us that in the process, they would gain significant competitive advantage and position themselves to reap massive rewards.

CivMin Prof. Paul Young has recently been appointed to the position of International (Foreign) Secretary of the Royal Society of Canada (RSC) and a member of Council. “I felt very honoured and humbled to be asked,” said Young of the appointment. “I’m very happy to take on the role.”

The RSC, founded in 1882, is also known as the Academies of Arts, Humanities and Sciences of Canada. Young has been involved for a number of years as a Fellow of the RSC and served on its Governance and Ethics Committee.

At the University of Toronto, Young’s impressive titles include his current role as Professor Emeritus and Senior Fellow Massey College, and has formerly served as the Vice-President, Research and Innovation (2007-2014), as well as Chair of the Department of Civil Engineering and Director of the Lassonde Institute for Mining. As an engineering geophysicist he has focused his research, and engineering career, on developing seismic methods and instrumentation to monitor fractures and rock quality. Over the past 40 years, he has pioneered techniques for monitoring and interpreting induced seismicity in the mining, petroleum and nuclear waste disposal industries.

Part of Young’s role is to liaise with other global academies and to engage collectively with G7, G20 and Commonwealth initiatives. This is a volunteer role, with a three-year appointment, so he will be continuing with regular U of T activities and commitments in parallel. In essence, the role is to research and assess, “Matters thought to be significant that can be brought to the political arena.”

With in-person meetings, especially those requiring international travel, impossible and now requiring a digital fix Young offered, “I’m now working with other people of the academies on a lot of Zoom calls.” The scheduled G7 meeting of global leaders was to be held in the U.S. this year (a video conference is to be substituted), so required work on scientific statements agreed to be brought forward to the political leaders for consideration. The result is three topics sent to G7 academies: Digital Health, The Nature and Importance of Basic Research, and Global Declines of Insect Populations and Potential Erosion of Vital Ecosystem Services.

When asked if he had sought out or applied for the position, a modest Young declared, “A call came out of the blue,” in reference to contact from the RSC president.

Story by Tyler Irving, U of T Engineering News

Two U of T Engineering professors have been awarded new Canada Research Chairs.

Professor Gisele Azimi (ChemE, MSE) now holds the Canada Research Chair in Urban Mining Innovation, while Professor Arthur Chan (ChemE) is the new Canada Research Chair in Atmospheric Chemistry and Health.

Azimi’s research focuses on innovative ways to recover valuable elements from unconventional sources. These include rare earth elements, such as neodymium and dysprosium, which are needed for the types of batteries and magnets found in technologically advanced products such as smartphones, electric vehicles and wind turbines.

Using unconventional techniques such as supercritical fluid extraction, Azimi and her team are developing new ways to recover these valuable elements from materials that would otherwise be discarded as waste — old electronic devices, batteries left over from electric vehicles, and even byproducts of the aluminum industry.

By converting waste into valuable products and developing extraction methods that are use less energy or produce fewer byproducts, Azimi is at the leading edge of a more sustainable resources sector. Earlier this year, she earned the Faculty’s McCharles Prize for Early Career Research Distinction.

Arthur Chan and his team study air quality, particularly the impact of particulate matter such as organic hydrocarbons or heavy metals on human health. These compounds can be carcinogenic or have other toxic effects. The goal is to measure these pollutants in urban air and trace their sources in order to prevent future pollution.

Recently, the team collected dust from homes in Fort McMurray, Alta., analyzing it for evidence of harmful toxic substances left in the aftermath of the devastating 2016 wildfire. Their study revealed normal levels of contaminants that are comparable to homes across Canada, and so far, no evidence of long-term health risks from fire-ash exposure in residents’ homes.

“These new Canada Research Chairs will accelerate the work of top researchers in critical areas and help translate their innovations into new technologies, processes, and business models,” said Ramin Farnood, Vice-Dean, Research at U of T Engineering. “We are very proud of the work that Professors Azimi and Chan are doing to build a more sustainable world.”

Meeting a critical need in a supercritical way

Story by Tim Lougheed, Chemical Institute of Canada

“”It has been almost a decade since Gisele Azimi was pursuing post-doctoral work at MIT, where she realized just how dependent our technology was becoming on rare earth elements, which pose significant environmental and economic challenges as they are being processed into components for everything from cell phone sensors to wind turbine generators.

“We are utilizing rare earths in all these applications and at the end of the day we just put them into waste,” she says. “The amount of recycling in those days was less than 1% around the world.”

This awareness inspired her to found the Laboratory for Strategic Materials when she later became a faculty member in the University of Toronto’s Departments of Chemical Engineering and Applied Chemistry and Materials Science & Engineering.

Her goal has been to find new ways of obtaining these valuable agents, ideal from places where they have already been used, so that they become renewable commodities that are much easier to obtain. Among the most striking examples of this work has been a novel approach to teasing small amounts of rare earths out of the cracks and crevices of cell phones, without the use of harsh solvents and a great deal of effort.

“Our technique is supercritical fluid extraction,” she explains, noting that at the comparatively modest pressure of about 7000 kPa (about 70 atmospheres) the ubiquitous gas CO2 turns into the perfect tool for the job. “It’s a liquid that behaves like a gas, so it’s a very efficient solvent that can penetrate into solid matrices easily.”

Best of all, she adds, CO2 is abundant, inexpensive, and perfectly safe, so it can be easily obtained and just as easily disposed after use. This outlook characterizes many of the Laboratory’s objectives, which includes activities such as technospheric or urban mining, which adopts a new perspective on waste products such as mine tailings and regards them instead as an accessible source of new agents.

Nor are Azimi’s interests limited to recycling of existing materials. She is also designing innovative hydrophobic surfaces that can be placed inside piping structures that are susceptible to scale, which can eventually clog the flow through these conduits. “We call these new materials ‘scale-phobic,” she says.

Azimi’s accomplishments have earned her the both the 2020 Canadian Journal of Chemical Engineering Lectureship Award and the 2020 CSChE Innovation Award. Later this year she will publish a paper about her work in the Journal, but in the meantime, think about how CO2 can give new life to the most valuable parts of your cell phone.
