Despite this early production, most copper used in the United States was imported from Chile until 1844, when mining of large deposits of highgrade copper ore around Lake Superior began. The development of more efficient processing techniques in the late1800s allowed the mining of lowergrade copper ores from huge openpit mines in the western United States.
· Copper Ore Processing Methods. 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 directsmelting ores are produced, the bulk of the copper ore ...

The Minto mine commenced Yukon mining operations in 2007 as an open pit mine. In 2012 the company began underground development on the Minto South Deposits while continuing to mine additional open pits as the primary mining method. Today, the mining is entirely underground and we are currently producing in the Copper Keel ore body.
Copper processing is a complied process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called hodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

Copper extraction refers to the methods used to obtain copper from its conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
