What drives GHG emissions from copper production ...

About 80% of global copper mine production comes sulphide ores that ore processed using grinding and flotation plants to produce concentrates for smelting. The rest comes from mines using dump or heap leaching, solvent extraction and electrowinning to produce cathode copper. Most copper mines are large, low grade, open pits.
