Jul 08, 2019· Copper smelting and refining facilities produce 2.5 million metric tons (MT) of smelter slag and 1.5 million MT of slag tailings per year. This is a large volume of slag, however, it is very small compared to comparable waste volumes from mining and crushing operations.

(PDF) Copper Recovery by the Cementation Method

Conventional Copper Extraction . Conventionally, copper is recovered by a pyrometallurgical process known as smelting. In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to ...

Furthermore, much faster extraction of copper values can be achieved than is presently possible. Also some ores which formerly could not have been treated economically because of restrictions on leach solution acidity imposed by conventional cementation technology can now be exploited economically.
