Various copper sulfides in copper-molybdenum ore

In most porphyry copper deposits, acoustic copper minerals chalcopyrite (CuFeS 2). However, secondary copper sulfide is often formed due to strong alteration and oxidation, such as chalcopyrite (Cu 2 S), copper ore (Cu 4 FeS), and copper blue (CuS). In the oxidation zone of the copper- molybdenum d

Electrical selection process

Electro-election is based on the separation of minerals and materials with different charges under the action of an external electric field. The electrical selection method uses different triboelectric charging properties, electrical conductivity and dielectric properties inherent in the material.
