Copper ore milling method

Copper Environmental Profile

copper mining: surface and underground mining. Due to copper being spread in relatively low concentrations over large areas, surface, or open-pit mining, is the predominant mining method for copper in the world. After mining, copper is produced by one of two process routes: pyrometallurgical or hydrometallurgical.
