Copper extraction - Wikipedia

Most copper ores contain only a small percentage of copper. The remainder of the ore consists of gangue of no commercial value. Gangue from copper mining typically contains silicate mineralsand oxides. In some cases these tailings have been retreated as the technology for recovering copper has improved. The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key
