01-05-2020· And with the decrease of easy-leaching gold ores, more and more gold would be recovered from refractory gold ores in the 21st century, and many of the refractory ores contain copper minerals. It was estimated that about 20% of gold deposits had significant copper-mineralization, which were usually associated with chalcopyrite, tetrahedrite, tennantite, bornite and chalcocite [ 1, 2 ].
