Nickel Sulfide Versus Laterite : The Hard Sustainability ...

2009-9-22  In general, production of nickel from sulfide ores involves either open cut or underground mining, followed by concentration via flotation, smelting of concentrates to produce a nickel matte, finally leading to refining of matte to produce a pure metal. It is common for mines, smelters and refineries to be in different locations, depending on local geographic factors. The processing of sulfide ores in this manner is known as

Sulfide Ore - an overview ScienceDirect Topics

Sulphide ores are a major source of Cu, Ni and precious metals. A basic principle of the extraction processes is to blow air into the molten sulphide in order to oxidise (1) S, which forms a gas and (2) Fe, which forms predominantly FeO and then partitions to a slag phase which covers the matte.

Hydrometallurgical Processing of Low-Grade Sulfide Ore

2018-10-7  of Finland, average nickel grade amounts to 0.27%, copper 0.14%, cobalt 0.02%, and zinc 0.56% [36]. In cases of technogenic waste processing, the standard ore grade can be even lower. This can be explained by the fact that ore mining costs have been already spent, and transport expenses are allocated to the remediation budget [15].
