Recovery of Ni Co Mn and Mg from nickel laterite CORE

Many of the impurities present in the hydrochloric acid leaching liquors obtained after the treatment of Ni laterite and serpentine ores can be removed in a preliminary purification step However Mn and Mg typically persist in the liquor In addition the liquor also contains Ni and Co

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
