Cobalt is widely dispersed in the environment in low concentrations. People are exposed to small amounts of cobalt by inhaling contaminated air, or consuming contaminated drinking water or food. The concentrations of cobalt in soil range from about 1 to 40 ppm and the amount of cobalt in the ...
Samsung SDI and Samsung Electronics have launched a joint cobalt pilot project in the Democratic Republic of the Congo. A contract to this effect between the companies, together with the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH, will aim to improve artisanal mining working c...
Chinese-owned companies are aggressively expanding cobalt mining in Congo and Indonesia even while prices crash, as they bid to raise market share of the metal used in batteries for the country's electric vehicle (EV) industry. Chinese cobalt producers have seemed unfazed by oversupply that has ...
(2009) recovered indium (In) through mechanochemical reduction of In2O3/ITO by milling with Li3N under a non-oxidative state of NH3 and/or N2 gas environment. Lee et al. (2013) recovered In from spent liquid crystal display (LCD) panels assisted with high energy ball milling and acid ...
[63] an area garnering increasing interest for deep sea mining ventures due to the mineral-rich environment within its domain. Anthropogenic input contributes as a non-natural source but in very low amounts. Dissolved cobalt (dCo) concentrations across oceans are controlled primarily by reservoirs ...
The majority of cobalt production achieved through recovery as a by-product of copper and nickel mining is in three principal geological settings: hydrothermal, magmatic and lateritic, with major producing deposits found in the Democratic Republic of Congo (DRC) and Zambia. About 36 per cent of ...

Congo governor on artisanal cobalt mining: 'We have nothing to hide' (Read more from the interview with the governorhere.) "We must work together to make the issue of traceability transparent and to make the sites safe and regularized," he said, adding that Apple and Samsung were some o...
It is perhaps notable that Glencore made this announcement shortly after the DRC government put a new mining code into effect that introduced a 50% super profit tax and increased government cobalt royalties from 2% to 10% (Darton, 2021). The new code also changed rules on capital gains and ...
The high volatility of the price of cobalt and the geopolitical limitations of cobalt mining have made the elimination of Co a pressing need for the automotive industry1. Owing to their high energy density and low-cost advantages, high-Ni and low-Co or Co-free (zero-Co) layered cathodes ha...
