The present invention relates to a new hydrometallurgical process for recovering nickel from nickel bearing raw materials, such as sulphide flotation concentrates. In general, the process involves the oxidative atmospheric pressure leaching of nickel sulphide concentrates using a sodium chloride/hydrochloric acid based leach media.

2021-11-25 Common examples of solvents include water, ethanol, methanol and acetone. The term ‘solvent’ can be defined as a substance that has the ability to dissolve a given solute to form a solution with it. Although solvents are mostly used in the liquid state, it is possible for solvents to exist in the solid and gaseous phase as well.

2020-9-6 NICKEL AND COBALT ORES: FLOTATION. The nickel content in such sulRde ores is generally low (0.2}3%) and varies from place to place in the same deposit. The low nickel content of the present-day nickel sulRde ores renders them unsuitable for either direct smelting or hydrometal-lurgical extraction, thus requiring beneRciation.
