how is copper ore mined underground

How Copper Ore Mined. Grades of sulphide ore mined from underground are substantially higher than open-pit copper ores, but make up a small proportion of total ore mined. In 2017, AME estimates underground sulphide ore contained an average 1.09% copper and made up 9% of the total copper ore mined, compared to 1.39% copper and 12% of the total
