(1). Copper in copper-nickel sulfide ore mainly exists in the form of chalcopyrite, and nickel mainly exists in the form of free nickel sulfide such as fennelite and pentlandite. In addition, most of the nickel is mainly endowed in pyrrhotite in the form of similar phenomena, so the most important process of beneficiation of copper-nickel sulfide ore is flotation separation, while …

Ore processing plant is divided into magnetic separation, flotation separation and gravity concentration. Flotation seperation process is mainly used to select metal minerals such as gold, silver, copper, lead, zinc, nickel. It can also be used for the selection of ferrous and non-metallic (such as graphite).
Froth flotation is widely used for concentration of base metal sulphide minerals in complex ores. One of the major challenges faced by flotation of these ores is the ever varying grade and mineralogy.
