The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.

Spain used to mine high-grade copper oxide ore from Cerro Verde and ship it to Wales in the mid-1800s. In 1970 the Peruvian Government acquired the Cerro Verde mine from Anaconda, which had owned the property since 1916, and mined oxide ores and built one of the world's first solution extraction/electrowinning (SX/EW) plants in 1972 ...

Ore is mined and processed at an onsite flotation processing plant capable of treating up to 24 million tonnes per annum (Mtpa). The plant currently recovers copper, gold and silver into a saleable concentrate. The primary ore is crushed and ground using Semi-Autogenous Grinding and Ball mills to a final grain size of approximately 180 microns.

Opencast mining - 90% of the ore is mined in opencast mining. Ores close to the surface can be mined after the cover layers have been removed. copper ores. An ore is a rock that contains enough valuable mineral to make it worth mining. In the case of copper, it pays to extract if there are about 2 kg of copper per 1.000 kg of ore (0,2%). Copper ...

Overview. Pressure Oxidation (POX) is a process used to extract gold, copper, zinc, molybdenum, and uranium from refractory ore bodies. The POX process utilizes elevated temperatures (roughly 230 degrees Celsius), elevated pressures (roughly 35 bar or 510 psi), and oxygen to liberate the minerals from refractory ores.

Open pit mining began at Oyu Tolgoi in 2011 and the copper concentrator, the largest industrial complex ever built in Mongolia, began processing mined ore into copper concentrate in 2013. Current infrastructure at Oyu Tolgoi will allow the mine to operate for decades to come.
