process of enrichment of nickel ore

  • Cobalt extractionWikipedia

    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
