Aprwhat Is The Procedure In Making Copper Ore Into Concentrate

The refining process begins by concentrating the copper ore. A series of conical crushers is used to concentrate the copper and eliminate large quantities of dirt. As the ore is ground into smaller particles it is mixed with water to form slurry. This slurry is then placed into a rod mill, which breaks the ore into even smaller pieces.

Innovations: How Do They Do That? How Copper Is Made

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.
