An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
Phelps Dodge is hardly a stranger to SX/EW, having first used the environmentally friendly process on a large scale in 1987. In 1985, the company initiated largescale leaching of oxide ores and waste dumps using sulfuric acid and, two years later, using SX/EW to recover the copper.

Modern biomining processes are largescale operations that involve the mining of ores and processing for several months (Fig. 1). Either through stripmining or blasting, raw ore is obtained for extraction of copper.
Discovered in the late 1800s, largescale copper mining became an economic success in the mid1930s and has dominated Zambia ever since (Frederiksen, 2010). Zambia''s attempts to develop through natural resource extraction have been repeatedly thwarted by economic mismanagement and countervailing global minerals prices.
Nov 04, 2013· The Cerro Verde copper mining complex includes a concentrator facility with ore milling capacity of 120,000tpd and a solvent extraction and electrowinning (SXEW) facility. A largescale expansion plan is underway to raise the concentrator capacity up to 360,000tpd by 2016. Cerro Verde has been operational since 1976.
Large scale mining versus small scale mining: Large scale mining usually involves a company with many employees. The company mines at one or two large sites and usually stays until the mineral or metal is completely excavated.
