Some factors that affect beneficiation of sulphide nickel–copper ores
Abstract. Sulphide Ni–Cu deposits occur typically in mafic and ultramafic igneous rocks and intrusions. The occurrence of minerals affects the separation efficiency of the sulphides. Coarse grained ores are often relatively easy to process, but some ores have altered in metamorphosis. Disseminated secondary minerals often require fine ...

But after the treatment, the calorific value is ranging from 5714.03 to 6531.46 kcal/kg. The Sombo and Dabaso coals also increase in their calorific value to 5462.78 kcal/kg and 5243.40 kcal/kg respectively. This shows that the beneficiation by froth flotation technique is an appropriate approach to increase the calorific value of the coal.

Addition of copper sulfate at pH values ranging from 7 to 10 may slow down floatability of iron sulfides. Excessive addition of copper sulfide may result in lower recovery due to oxidation of xanthate into dixanthogen in solution, thus reducing the effectiveness of collection. Copper sulfate addition also appears to impact froth stability.

Froth Flotation Process
Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.
