#Mining sub-Saharan Africa is expanding rapidly. This poses a key threat to tropical forests.
"For every hectare of direct deforestation due to the mine footprint, mining triggers, on average, 34 hectares of additional offsite loss within five years through ancillary activities, including agriculture and settlements. Mines extracting cobalt and copper—key energy transition minerals—caused the highest amount of additional deforestation."

To complete its green transition, Europe should mine its own trash. Lithium in old batteries.
Cobalt in discarded electronics. The rare earths in retired wind turbines. A landmark EU-funded study finds these buried materials could supply over half of what the clean energy economy will need.

Scientists achieve massive breakthrough on an alternative to #LithiumIon batteries — why this 'significant advancement' matters
by Laurelle Stelle, January 13, 2026
"Researchers have recently discovered a way to make an efficient battery out of #zinc — an inexpensive, commonly found metal — instead of the #RareMetals used in lithium batteries.
"Most rechargeable batteries today are lithium-ion batteries, which include other metals like cobalt and nickel, Tech Xplore reports. As electric vehicles (#EVs) and large-scale energy storage get more common, we'll need more and more of those metals — but because they're uncommon, the costs are often massive.
"Many researchers are working on cheaper battery options to reduce or replace these metals. One Chinese company has created a car powered by a #SodiumBattery, and a University of Maryland researcher has invented a partly #BiodegradableBattery made of zinc and #CrabShells. Researchers have even found not one but two ways to store energy in ordinary #sand.
"According to Tech Xplore, this new project, led by Xiulei 'David' Ji of Oregon State University, offers yet another alternative to lithium-ion batteries: accessible, efficient zinc metal batteries.
"The secret is a new electrolyte developed by Ji and his team, Tech Xplore explains. A battery electrolyte is a liquid inside the battery that helps aid the chemical reactions to store and release energy.
"Unfortunately, past electrolytes in #ZincBatteries were not very efficient. Much of the energy stored in the battery was previously used up in extra, unwanted chemical reactions. Not only did that mean the battery couldn't release as much energy as it had put into it, but it also generated dangerous hydrogen gas. This meant that zinc wasn't practical for #RechargeableBatteries.
"Ji's team has created a new electrolyte formula that almost eliminates these unwanted reactions, Tech Xplore reports. It forms a protective coating on the zinc component of the battery that prevents that type of energy loss. A similar protective coating is what allows lithium-ion batteries to release more than 99% of the charging energy. The new zinc battery releases 99.95% of the energy it is charged with on each cycle.
"Not only is the zinc battery efficient, but it's also safer than a lithium-ion battery, according to Tech Xplore. The new electrolyte isn't flammable, while the ones used in lithium-ion batteries often are combustible. Both zinc and the components of the electrolyte are also cheaper and more common than the materials used in lithium-ion batteries.
" 'The breakthrough represents a significant advancement toward making zinc metal batteries more accessible to consumers,' Ji told OSU News and Research Communications. "These batteries are essential for the installation of additional solar and wind farms. In addition, they offer a secure and efficient solution for home energy storage, as well as energy storage modules for communities that are vulnerable to natural disasters.
"Thanks to the work of Ji and his team, Tech Xplore suggests rechargeable zinc batteries are likely to hit the market in the near future."

#Winemaking acid powers cleaner way for cobalt-nickel recovery from #BatteryWaste
Scientists use #TartaricAcid and electrowinning to split #cobalt and #nickel from battery waste for cleaner #recycling.
By Neetika Walter
Mar 11, 2026"Scientists have developed a cleaner way to separate cobalt and nickel from lithium-ion battery materials using an electrochemical technique boosted by a naturally occurring acid commonly associated with wine.
[...]
"The researchers say the approach could be particularly useful for '#UrbanMining,' the process of recovering valuable #minerals from discarded #electronics and spent #batteries. Countries with limited mining resources are increasingly looking to #recycling to secure supplies of critical materials.
" '#Electrowinning’s edge in urban mining gives us a practical pathway to turn battery waste into a valuable resource for cobalt and nickel, while also helping the United States reduce its reliance on foreign supply chains,' Liu says."

Answer: "No."
Most #CriticalMinerals are on #IndigenousLands. Will miners respect #TribalSovereignty?
by Taylar Dawn Stagner, March 26, 2025
"#Mining — whether for #FossilFuels or, increasingly, the critical minerals in high demand today — has a long history of perpetuating violence against #IndigenousPeople. Forcibly removing tribal communities to get to natural resources tied to their homelands has been the rule, not the exception, for centuries.
"Today, more than half of the mineral deposits needed for a global energy transition — including #lithium, #cobalt, #copper, and #nickel to make things like #batteries and #SolarPanels — are found near or beneath Indigenous lands.
"In 2007, the United Nations adopted a resolution called the Declaration on the Rights of Indigenous Peoples [#UNDRIP] that included the right to free, prior, and informed consent to the use of their lands, a concept known as #FPIC. This principle protects #IndigenousPeoples from being forcibly relocated, provides suitable avenues for redress of past injustices, and gives tribes and communities the right to consent to — and the right to refuse — #extractive industry projects like #mining.
"There’s a lot at stake: When followed, FPIC promises a process that gives Indigenous peoples a voice in how their homelands are used, as well as the right to say no to development altogether. And when it’s not, which is the vast majority of the time, #TribalCommunities are further #disenfranchised, facing #violence and #ForcedRelocation as their #sovereignty and rights are ignored.
"There are an estimated 5,000 tribal communities around the world, encompassing roughly 476 million people across 90 countries, according to the U.N. Different tribes have different opinions on mining, but rarely is their legal right to refuse extraction projects recognized, even under the 2007 declaration.
"Grist talked with five experts to better understand what free, prior, and informed consent should look like in this new era of mineral extraction. Their responses have been edited for length and clarity."

"Critical minerals such as lithium, cobalt and nickel are becoming the “oil of the 21st century” as the scramble for precious metals deepens poverty and creates public health crises in some of the world’s most vulnerable communities, a report by the UN’s water thinktank has found.
The investigation by the United Nations University Institute for Water, Environment and Health (UNU-INWEH) concluded that the growing demand for lithium, cobalt and nickel used in batteries and microchips is draining water supplies, eroding agriculture and exposing communities to toxic heavy metals.
An estimated 456bn litres of water were used to extract 240,000 tonnes of lithium in 2024, the researchers found, with little of the financial benefit or technological advances from the green energy transition or AI boom reaching the affected communities.
“Critical minerals are quickly becoming the oil of the 21st century,” said Kaveh Madani, director of UNU-INWEH and the 2026 Stockholm water prize laureate.
“What we are selling as a solution to sustainability is actively hurting people somewhere else in the world. How can we then call the transition green or clean?”
According to the International Energy Agency (IEA), growth in demand for key energy minerals has been strong in recent years, with lithium demand rising by nearly 30% in 2024. The production of rare earths almost tripled between 2010 and 2023 as demand for electric vehicles (EVs) and powerful computer chips has soared.
The report found that while EVs may reduce emissions by consumers in North America and Europe, the environmental and health costs are borne by communities far away, in the mining regions of Africa and Latin America."

#Mining the deep #ocean
Policymakers debate if we even need deep ocean mining and if we can do it safely.
More than 13,000ft below the surface of #Pacific Ocean, a more-than-70-ton machine trundled like a tank on its caterpillar tracks for a tenth of a mile—sucking up potato-sized nodules of rock packed with #copper, #manganese, #cobalt, and #nickel.

#SodiumIonBatteries offer an alternative to tricky #lithium
Oct 26th 2023
Excerpt: "Fortunately, lithium is not the only game in town. As we report this week, a clutch of firms are making batteries based on sodium, lithium’s elemental cousin. Since sodium’s chemical properties are very similar to those of lithium, it too makes for good batteries. And sodium, which is found in the salt in #seawater, is thousands of times more abundant on Earth than lithium and cheaper to get at. Most of the companies using sodium to make batteries today are also Chinese. But pursuing the technology in the West might be a surer route to energy security than relying heavily on lithium.
"Besides its abundance, sodium has other advantages. The best lithium batteries use #cobalt and #nickel in their electrodes. Nickel, like lithium, is in short supply. #Mining it on land is #EnvironmentallyDestructive. Proposals to grab it from the #seabed instead have caused rows. A good deal of the world’s cobalt, meanwhile, is extracted from small mines in the #DemocraticRepublicOfCongo, where #ChildLabour is common and working conditions are dire. Sodium batteries, by contrast, can use #electrodes built from #iron and #manganese [and wood #lignin], which are plentiful and uncontroversial. Since the chemical components are cheap, a scaled-up industry should be able to produce batteries that cost less than their lithium counterparts.
"Sodium is not a perfect replacement for lithium. It is heavier, meaning sodium batteries will weigh more than lithium ones of an equivalent capacity. That is likely to rule them out in some cases where lightness is paramount. But for other applications, such as #GridStorage or #HomeBatteries, weight is irrelevant. Several Chinese carmakers are even beginning to put sodium batteries in #ElectricVehicles."

"Sodium is not a perfect replacement for lithium. It is heavier, meaning sodium batteries will weigh more than lithium ones of an equivalent capacity. That is likely to rule them out in some cases where lightness is paramount. But for other applications, such as #GridStorage or #HomeBatteries, weight is irrelevant. Several Chinese carmakers are even beginning to put sodium batteries in #ElectricVehicles."

"#TheElementsOfPower: A Story of War, Technology, and the Dirtiest Supply Chain on Earth," a new book by journalist #NicolasNiarchos, paints a semi-apocalyptic vision of that #cobalt’s origins: corrupt bargains between politicians and foreign companies, displacement and environmental destruction, cave-ins that bury miners alive."
