Copper smelting plants separate elemental copper from copper concentrates for a metallurgical circuit involving crushing, grinding, classifiion and flotation.
Mining and milling use about 60% of the total consumption, because low-grade ore (0.6% copper) is now being mined. Most copper is extracted by smelting.
The next step is to feed the crushed ore into a wet grinding process in tumbling mills. These mills contain the ore, water and steel balls and further reduce the
