Important factors include the mode of occurrence of nickel (and other economic metals), permeability of the ore, ore mineralogy, ore textures, and gangue mineralogy. The type and degree of hypogene and supergene alteration experienced by magmatic nickel sulphide deposits is the principal controlling influence in the development of these parameters.

Recoverable economic copper sulphide minerals such as chalcopyrite, bornite, chalcocite and covellite often occur together in varying proportions in the major copperbearing ores, and have individual flotation requirements and characteristics. Pyrite also occurs in these ores to varying extents as the sulphide gangue, and is problematic because ...

The extraction of metals from ores involve three major steps: 1. Concentration of the ore, 2. Isolation of the metal from its concentrated ore, and. 3. Purifiion of the metal. For sulphide ores, Froth floatation method is used to concentrate the ore by removing gangue particles from it. In this process, to an aqueous suspension of the ...

06/02/2006 · While copper is sometimes found in the native state, sulphide minerals such as chalcopyrite (CuFeS 2) and bornite (Cu 5 FeS 4) are the most important sources of copper in Canada. Copper mining operations are established in loions where these minerals exist in sufficient concentration and volume to permit their economic exploitation.

Sulphide minerals are one of the most important sources of value metals, such as gold, silver, copper, zinc, etc. Due to the strong sulphur binding to these minerals, metals are usually extracted by pyrometallurgical route or hydrometallurgy with chemical oxidation. Of these, hydrometallurgy apparently has a lower environmental impact, which has
