Copper Applications in Metallurgy of Copper & Copper Alloys. Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore.

The ore is then ground finely before the copper-bearing sulfide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material, or gangue. Depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate typically contains between 25 and 30% copper, however may be as high as approximately 60% copper.

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 direct-smelting ores are produced, the bulk of the copper ore

Mines are faced with numerous challenges, such as falling raw material prices, declining metal grades in the ores and higher energy prices. Especially because ore processing is particularly energy-intensive, the industry is again focusing on the saving of energy. This report shows what are the key energy saving considerations in the copper and gold mining sectors.

Sulfide ores are used to produce a matte (40 – 50 wt % Cu) and a disposal slag (ca. 0.5 wt % Cu). In contrast, oxide ores are processed directly to impure black copper ( 95 wt % Cu) and to a copper-rich slag. The two ore types can be smelted together to produce matte and a slag with low copper content. Another

COPPER Copper production
An analysis of energy usage in the production of refined cathode copper was made from mining ore to cathode copper. In mining copper ore the greatest energy consumers are ore hauling and blasting. Another important factor is the “recovery efficiency” of the metallurgical processes used to extract the copper. The mining and mineral concentrating energies are directly proportional to the

70% of the world’s copper resources – estimated to be worth more than $20 trillion – are tied up in primary sulfide ores. The majority of this ore is too low-grade to justify traditional processing, and the alternative low-cost method of leaching does not work well on primary sulfides, despite decades of industry efforts.

Primary production uses about 170 x 10/sup 12/ Btu total energy annually (about 100 x 10/sup 6/ Btu/ton pure copper produced from ore). Mining and milling use about 60% of the total consumption, because low-grade ore (0.6% copper) is now being mined. Most copper is extracted by smelting sulfide ores, with concomitant production of sulfur dioxide.
