    How copper is made

    Despite this early production, most copper used in the United States was imported from Chile until 1844, when mining of large deposits of high-grade copper ore around Lake Superior began. The development of more efficient processing techniques in the late-1800s allowed the mining of lower-grade copper ores from huge open-pit mines in the western United States.

    Copper and magnetite are recovered on behalf of Foskor (a neighbouring mining company) by toll-processing 20,000 Tpd of marginal ore from stockpiles from the open pit operation. The conventional process route is also applied to underground ore available in excess of autogenous milling capacity.

    Leaching process for copper ore includes acid leaching and ammonia leaching. Leaching process is mainly for oxide copper that is very difficult to be extracted by flotation. Also for some copper ore it is combined by both oxide copper ore and sulfide copper ore, after processing test combined processing technologies can also be adopted to extract copper.

    Copper

    Copper is one of the few metals that can occur in nature in a directly usable metallic form (native metals).This led to very early human use in several regions, from c. 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, c. 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another
