Copper processing begins with mining copper ore, which contains less than 1% of copper, and ends with sheets of 99.99% pure copper (cathodes). Copper mining generally takes place through open-pit mining, in which a series of stepped benches are dug deeper into the earth. Yet, it can also be mined underground, through horizontal tunnels.
A simplified schematic drawing of copper flotation flowsheet. Run-of-mine open pit ore will be crushed in a gyratory crusher. The crushed ore will be processed by means of semi-autogenous and ball mill grinding followed by rougher flotation, regrind, cleaner flotation, and dewatering to produce copper concentrate. The concentrate will be trucked via the existing …
