The extraction of nickel process generally consists of crushing, sieving, washing, re selection, grinding, and slurry concentration, or the nickel leaching method. The target element nickel distribution varies with the nature of the ore, mostly contained in fine grained grades. For example, the nickel minerals of the Ramu laterite mine in Papua ...
for the separation of impurities such as zinc, copper and, more particularly, manganese from nickel and cobalt are used by each project. Mihaylov et al. have developed a novel hydrometal lurgical process for nickel and cobalt recovery from the Goro later ite ore. Their study proposed the simultaneous extraction of 0.6 g/L
process flowsheet into which the new separation process is inserted. After the initial leaching process of the nickel ore or concentrate, and subsequent liquid/solid separation, purification is needed to remove: a) Copper, if present in commercial quantities, by solvent extraction.
Separation of nickel and iron from lateritic ore using digestion roasting leaching precipitation 569 As result, significant amounts of nickel, cobalt and iron were transformed to metal sulfate forms, which can be leached in water easily. However, it is known that the iron content of the final nickel product must be as low as possible.
Gravity separation is an effective method which has been applied to process many types of minerals such as nickel, tin, barite, and ilmenite (Angadi et al. 2017;Molaei, Razavi and Chehreh Chelgani ...
