extractive metallurgy of nickel cobalt and platinum group

two different nickel sulfide intermediates must be refined to pure nickel and cobalt products: sulfide matte from nickel sulfide smelting and converting and sulfide precipitates from nickel laterite leaching. these data indicate that hydrometallurgy is the principal method for making high-purity nickel from these mattes and sulfide intermediates.

nickel sulfide versus laterite : the hard sustainability

are easier to process through conventional mining smelting and refining compared to laterite ores which require intensive hydrometallurgical processing (such as high pressure acid leaching or hpal). this means that laterite ores typically require substantially more energy and chemicals to produce than sulfide nickel.

cobalt extraction - wikipedia

nickel-cobalt lateritic ores can be treated by either hydrometallurgical processes or pyrometallurgical processes such as matte or ferronickel smelting which require the entire ore to be melted and the metal values to be separated from the residual components of the ore. the hydrometallurgical process for laterite ore can use sulfuric acid or ammonia leach solutions.
