COPPER Copper production

Cu) must be concentrated by beneficiation. The valuable minerals like chalcopyrite are intergrown with gangue. Therefore, in the first step the lumpy ore is crushed and milled into fine particles (< 100 µm) to liberate the individual mineral phases. Typical equipment for crushing to about 20 cm are gyratory and cone crushers. Then wet grinding

Introduction to Mineral Processing or Beneficiation

Within extractive metallurgy, the major divisions in the order they may most commonly occur are, Mineral Processing (or Beneficiation), Hydrometallurgy, Pyrometallurgy, and Electrometallurgy. The last steps in the winning of metals are in Physical Metallurgy where the composition and treatment of metals are varied to provide desired physical and mechanical properties.
