Copper mining costs are being reported ranging from around 2pound to a high of 3.20 per pound. As Chinas economy cools to a 5 growth rate, they require fewer resources, such as steel and copper, so the demand weakens, but if American and European economies ever recover, copper will again rise to the 4 per pound level.
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.
Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituentssuch as alumina, limestone, pyrite, and silicaso that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.
The reactivity series shows metals in order of reactivity. The reactivity of a metal is related to its tendency to form positive ions. Iron and aluminium are extracted from their ores in various ways.
Dec 20, 2013 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 ...
