Nickel laterite HPAL circuits are known for their complexity and have presented a large number of challenges to process engineers worldwide. An attitude commonly encountered by the author is that the beneficiation of the ore is relatively simple and that the difficult problems are in the realms of hydrometallurgy. On a number of occasions beneficiation …

The goal of ore beneficiation, or mineral processing, is to maximize the economic value of the extracted minerals by increasing the concentration of valuable minerals and removing impurities. Ore beneficiation can extract the following materials. Metallic ores: Iron, copper, gold, silver, lead, zinc, nickel, lithium, and tin.
