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. The usual method of nickel extraction from sulRde

The solvent used for the grinding process was N-methy-2-pyrrolidone (NMP) solution. Eventually, a uniform slurry was obtained. The uniform slurry …
Flash smelting. Flash smelting (Finnish: Liekkisulatus) is a smelting process for sulfur-containing ores including chalcopyrite. The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore. It has also been adapted for nickel and lead production.

A process for extracting nickel from a low-grade nickel complex ore. The process features simultaneously grinding and leaching of the ore with an aqueous ammoniacal leach solution.
The solution after nickel reduction still contains zinc, nickel and cobalt. Hydrogen sulphide is used to precipitate metal ions from the liquor as insoluble sulphides in two stages. In the first stage, zinc is recovered as a saleable byproduct. In the second stage, remaining nickel and cobalt are recovered and recycled to the leaching circuit.
