Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze copper-tin alloy about 3000 BC, was the first engineering material known to man.
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 ...
Copper processing - Copper processing - Ores Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.
By the use of the SXEW process, copper can now be extracted away from the iron and other impurities in solution and further purified and reduced to metallic metal by electrolysis without ever having to be melted. Further, through the use of biooxidation, it is now possible to leach many of the copper sulfide minerals present in the ore.
However, some slags may contain remnant minerals that can be a potential source of metal release to the environment. Acid rock drainage from waste rock. Although the character of waste rock varies with the type of ore, many waste rocks contain sulfide minerals associated with metals, such as lead, zinc, copper, silver, or cadmium.
