Typical Copper Oxide Ore Leaching Operations OneMine

Brought on stream in 1975, the 10,000-tpd copper oxide processing plant of Anamax Mining Co. at Twin Buttes, Ariz., is now at design capacity. Based on acid agitation leaching, solvent ion exchange, and electrowinning, the Anamax plant bridges an ore to metal gap by producing mine site copper cathodes from lime-bearing oxidized feed.

Dump leaching Wikipedia

Dump leaching is an industrial process to extract precious metals and copper from ores.. Dump leaching is similar to heap leaching, however in the case of dump leaching ore is taken directly from the mine and stacked on the leach pad without crushing where, in the case of gold and silver, the dump is irrigated with a dilute cyanide solution that percolates through the ore to dissolve gold and

Copper Ore an overview ScienceDirect Topics

2.7.4.1.2 Copper Ore Leaching by Ore Type. The leaching of copper ores is conducted somewhat differently depending on the minerals present in the ore. Oxide ores containing chrysocolla, malachite, azurite, cuprite, etc., are readily amenable to acid leaching. An acid solution is often mixed with the ore during agglomeration to initial leaching
