Common & Basic Formulas for Mineral Processing Calculations

By referring to the tables "Minerals and Their Characteristics" (pages 332-339) it is seen that the perfect grade of a copper concentrate will be 63.3% when the copper is in the form of bornite, 79.8% when in the mineral chalcocite, and 34.6% when in the mineral chalcopyrite. A common association is that of chalcopyrite and galena.

Copper ore, in concentrations ranging from 0.29 percent to ten times that amount, is mined from open pit or underground mines. The crushed mine ore is ground in rod and ball mills and then sent to flotation machines where the copper mineral rises to the top in a froth, making a copper concentrate of approximately 30 percent, 27 percent iron and 33 percent sulfur.
