Mining Methods Used To Mine Copper

digging deeper: mining methods explained | anglo american,long-wall mining, where a long wall of coal is mined in a single slice, usually by a large machine. sub-level-caving, where levels of the ore are blasted by explosives; and ; block caving, where large areas of the ore body are blasted and then extracted with the assistance of gravity. we use these three different types of underground mining techniques for coal, diamonds and copper. 3. underwater mining.copper mining and extraction sulfide ores,mining copper about 200 years ago the uk was an important world source of copper and tin and there were mines in cornwall and devon. these mines have now closed and today the biggest copper mines are in chile (escondida mine) and indonesia (grasberg mine). these produce many millions of tonnes of copper ore per year..
