Around 60% of the world’s cobalt supply comes from the mineral-rich Katanga Copper belt, in the Democratic Republic of the Congo. Previous research by KU Leuven and the University of Lubumbashi (2009) had already found high concentrations of trace metals in the urine of people living close to mines. —Nkulu et al.
Roughly 60% of mined cobalt is sourced from the Democratic Republic of Congo (DRC). The paper is published in the ACS journal Environmental Science & Technology. The element is often recovered as a byproduct from mining copper and nickel, meaning that demand and pricing for those other metals affects the availability of cobalt.
The BMW Group has commissioned two US universities to conduct a scientific analysis of water consumption in the lithium extraction process. The aim of the University of Alaska-Anchorage and University of Massachusetts-Amherst study will be to investigate the impacts of lithium extraction on the hydrologic environment in Latin America.
Researchers at the University of California, Irvine and four national laboratories have devised a way to make lithium-ion battery cathodes without using cobalt.
At present, the US relies on imports from nations such as China and the Democratic Republic of Congo for these critical materials. National laboratories, universities, industry, and nonprofit organizations may apply for the three-year awards, to be selected based on peer review.
That’s according to Dr. Michael Moats, professor and interim chair of materials science and engineering at Missouri University of Science and Technology, who says reducing carbon emissions from energy systems in the United States will increase the need for metal production by two to six times per kilowatt of energy production.
Elsewhere in West Africa, Angola, Equatorial Guinea, Gabon, Congo and Cameroon collectively waste about 10 billion cubic meters of natural gas every year. —David Victor, director of the Laboratory on International Law & Regulation at the University of California San Diego.
The scientific case for such a strategy was laid out in an Op Ed in The New York Times by Professor Veerabhadran Ramanathan, from the Scripps Institution of Oceanography at the University of California, San Diego, and his colleague, Professor David Victor.
A team of researchers led by Brown University has found that Lake Tanganyika in east Africa—the second-oldest and the second-deepest lake in the world—has experienced unprecedented warming in the last century. A paper on their work was published online 16 May in the journal Nature Geoscience. Resources.
In 2019, 64% of the world’s Co mine production was supplied by the Democratic Republic of Congo, with most of the processing occurring in China. Refinement of materials—both critical and not—for battery cathode. fabrication generally flow through China.
Research groups from Iowa State University and the Salk Institute for Biological Studies have uncovered the function of three plant proteins, a discovery that could help plant scientists boost seed oil production in crops, thereby benefitting the production of food, biorenewable chemicals and biofuels.

million tons of identified lithium resources, respectively, while Brazil, Congo, and Serbia each contain approximately 1 million tons. Among the other countries, identified lithium resources for Bolivia and Chile total 9 million tons and in excess of 7.5 million tons, respectively. China and Argentina total 5.4 million tons and 2.6
The Democratic Republic of Congo produces 70 percent of the world's cobalt, and most of the world's nickel sits under Indonesian rainforests. Craig Smith , an oceanography professor at the University of Hawaii at Manoa , who has led seven research expeditions to the CCZ. million to assess the impacts of deep-sea mining in the CCZ.
Chinese firms own, operate or finance most of the Democratic Republic of Congo’s cobalt mines, the Labor Department said in a recent report. Last year, a U.S. law took effect banning imports from China’s Xinjiang region over concerns about forced labor.
A CleanTechnica interviewee argues that automakers cannot make the excuse that it's too complicated to know who their suppliers are and how their suppliers are violating human rights.
Now in its twentieth year, the biennial report is produced by researchers at Yale and Columbia Universities in collaboration with the World Economic Forum. India and Bangladesh come in near the bottom of the rankings, with Burundi, Democratic Republic of the Congo, and Nepal rounding out the bottom five.
