Additionally, todays mining equipment makes it possible to reduce waste and decrease chemical exposure during all phases of the copper mining process. The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using todays compact
2CuFeS 2 s + 3O 2 g 2FeOs + 2CuSs + 2SO 2 g As SO 2 is hazardous, it has to be removed from the gases released into the environment. One way of solving the problem is to convert it to sulfuric acid. This is either sold for industrial use or used to extract oxide ores of copper by leaching. Stage 4: Smelting with fluxes
