the dried copper concentrate of about 28 percent copper is shipped to the smelter. it represents less than one percent of the material removed from the mine. concentrate is just a fine powder of the mineral chalcopyrite which is a naturally occurring compound of copper, iron, and sulfur.

ball mills - mine

ball mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. to achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.
