Title: Nickel and cobalt extraction from laterite oresPedro Paulo Medeiros Ribeiro, UFRJ Federal University of Rio de Janeiro, Brazil

Extraction Cobalt does not naturally exist on Earth, but you can find it almost everywhere: the soil, in mineral deposits, and on the seafloor. Cobalt is always combined with other elements, such as nickel, copper, iron, or arsenic. It is usually collected as a by-product from the mining of other metals. Sustainable cobalt sourcing
