Typi-cally the grade of the ores is greater than 0.5 percent Ni and the mining camp generally contains more than 100,000 tons (t) Ni (Table 1). Each individual ore deposit generally con-tains greater than 10,000 t Ni. Ni sulfide

In the extraction of copper from its sulphide ore, when ore is subjected to roasting, some of it is oxidised to Cu 2 O which reacts with the remaining Cu 2 S (sulphide ore) to give copper metal. Cu 2 S +2Cu 2 O → 6Cu +SO 2 ↑ In this process, Cu 2 S behaves as reducing agent.

nately, in case of sulfide ores, the method suffers from inadequate detection of lightweight materials such as sulfur and the common nature of iron, as iron is constantly present in several different minerals found in sulfide ores. Raman spectroscopy can be used to detect the minerals instead of mere elements of ore.

The mineralogical nature of the ores is dependent on a number of factors during sulfide liquid fractionation. The most significant of these with regard to the mineralogy of the two most important metals, platinum and palladium, is the presence and concentration of semimetals such as bismuth and tellurium within the mineralising sulfide liquid.
