Ottawa orders Chinese divestment in three Canadian critical minerals companies – by Niall McGee and Steven Chase (Globe and Mail – November 3, 2022)

https://www.theglobeandmail.com/

Ottawa is ordering Chinese state-owned companies to immediately divest their interests in three Canadian critical minerals companies, after the federal government faced an avalanche of criticism earlier in the year for allowing too much investment from the Asian superpower into the domestic mining sector.

The government’s order marks the second time in a week it has taken a more aggressive stand against China, after allowing it to acquire a Canadian critical minerals company earlier this year amid little scrutiny.

Opinion: Laurentian must turn its legacy into a new vision for the future – by Nadia Mykytczuk (Sudbury Star – August 30, 2022)

https://www.thesudburystar.com/

Among other steps, LU should focus on being ‘Canada’s mining university’

As we get closer to the vote on Sept. 14 that will ultimately decide the fate of Laurentian University following a grueling, agonizing and, at times, nasty CCAA process, I find myself torn between our collective struggle to find closure, the empathy I feel for those whose lives were turned upside down, and mourning what we have lost in our Laurentian and Sudbury community.

As one of the terminated faculty, I have lived the pain of losing my job, my hard-earned academic career, and tenure. Even more difficult has been seeing many of my colleagues and their families leave our wonderful community.

Tapping mineral wealth in mining waste could offset damage from new green economy mines – by Anita Parbhakar-Fox, Kamini Bhowany, Kristy Guerin, Laura Jackson and Partha Narayan Mishra (The Conversation – May 30, 2022)

https://theconversation.com/

To go green, the world will need vast quantities of critical minerals such as manganese, lithium, cobalt and rare earth elements. But to some environmentalists, mining to save the planet is a hard pill to swallow if it leads to damage to pristine areas.

The good news is that in many cases, the mining for these minerals has already been done. After Australia’s major miners dig up iron ore, billions of tonnes of earth and rock are left over. Hidden in these rock piles and tailing dams are minerals vital to high tech industries of today and tomorrow.

Metal-eating bacteria could help extract $7B-$10B worth of minerals at Copper Cliff

The key to supplying the automotive industry with enough electric vehicle batteries may rest in a toxic eyesore: Sudbury’s vast tailings ponds.

Tailings are the waste material left over from ore extraction processes — often mixed with water and stored in ponds. But for several years, the potential for leaks of toxic substances into the surrounding environment has raised concerns about these tailings and questions about what, if anything, can be done with them.

The Drift: Could Sudbury be a global leader in ‘green’ mining? – by Ian Ross (Northern Ontario Business – May 25, 2022)

https://www.northernontariobusiness.com/

Toronto’s Bactech Environmental and Sudbury’s MIRARCO want to mine nickel, cobalt and iron the natural way

Sudbury may be on the cusp of an innovative new phase in its 40-year regreening effort. What an army of volunteer tree planters once accomplished to reforest a barren landscape, blackened by a century of nickel roasting and smelting, now a swarm of microscopic bugs could provide in an environmentally friendly solution to clean up a massive amount of mined waste rock while recovering valuable minerals in the process.

BacTech Environmental Corp., a Toronto green technology company, is pulling a proven technology out of mothballs to relaunch it in Sudbury to “liberate” millions of dollars worth of battery-grade metals out of mine tailings through a proprietary bioleaching process.

[Partner Content] Tech update: A tiny solution that could lighten the impact of mining; a new platform that encourages the hiring of Black professionals; and other news – by Janey Llewellin (Toronto Star – February 10, 2022)

https://www.thestar.com/

As the production of electric vehicles, solar panels and wind turbines ramps up, so too does the demand for “green” minerals. (In fact, the World Bank predicts that production of such minerals as lithium, cobalt and graphite will increase by nearly 500 per cent by 2050.) Yet traditional means of extraction often exacts a heavy toll on the environment. To lighten the impact, some companies are turning to a tiny solution: microbes found underground.

A new initiative with Canada’s Digital Technology Supercluster is looking to identify helpful microbes that can replace the use of chemicals in mining and site remediation. The project aims to build a repository of microbes and geochemical data by extracting the DNA from more than 15,000 mining sites.

Scientists want to engineer bacteria to sustainability mine rare earths – by Valentina Ruiz Leotaud (Mining.com – November 21, 2021)

https://www.mining.com/

A new study published in Nature Communications describes a proof of principle for engineering a bacterium, Gluconobacter oxydans, that takes a first step towards meeting skyrocketing rare earth element demand in a way that matches the cost and efficiency of traditional thermochemical extraction and refinement methods and is clean enough to meet US environmental standards.

“We’re trying to come up with an environmentally friendly, low-temperature, low-pressure method for getting rare earth elements out of a rock,” Buz Barstow, the paper’s senior author and an assistant professor at Cornell University, said in a media statement.

What mining, oil and gas industries can learn from Sudbury, the city that went from major polluter to thriving environment – by Nadia Mykytczuk (The Conversation – August 25, 2021)

https://theconversation.com/

Nadia Mykytczuk is the Interim CEO/President of MIRARCO, Laurentian University.

When Prime Minister Justin Trudeau met with Swedish environmental activist Greta Thunberg in Montréal two years ago, he promised to plant two billion trees by 2030 to help Canada meet its net-zero emissions goal.

Planting trees, however, is hard work. It takes money and planning. But a re-greening roadmap exists.

Sudbury, the largest city in Northern Ontario, transformed itself after decades of environmental devastation, brought on by the mining industry. Other communities and industries, like oil and gas, can replicate the city’s efforts to aid in global efforts to fight climate change.

A devastated landscape

For almost 100 years, Sudbury’s community and environment were blanketed in sulfur dioxide and metals released from the smelting of nickel ore.
