Copper Environmental Profile
After mining, copper is produced by one of two process routes: pyrometallurgical or hydrometallurgical. Within the pyrometallurgical route, the mined ore is crushed and milled, followed by a concentration step using flotation. The obtained copper concentrates contain on average 30 percent copper, but grades can range from 20 40 percent (ICSG ...

Copper Facts
Copper's thermal conductivity, or capacity to conduct heat, is about 60 percent greater than that of aluminum, so copper can remove much more heat more quickly. The more heat removed from the processor, the more efficiently it will operate, with less potential for damage to other critical components.
Copper Ore
The copper ores being mined in 2010 are too lean in copper (–2% Cu) to be smelted directly. Heating and melting their huge quantity of waste rock would require prohibitive amounts of hydrocarbon fuel. Fortunately, the Cu–Fe–S and Cu–S minerals in an ore can be isolated by physical means into highCu concentrate, which can then be smelted economically. The most effective method of ...

Introduction: The percent of copper in ore can be measured and based on this information, people can decide whether or not the ore is worth being mined. Acid is used to dissolve the compound which turns the compound into a blue mixture. After the copper is extracted, ammonia can be added to enhance the color and also neutralize the acid by transforming it into a complex ion.

Innovations: How Do They Do That? How Copper is Made
Copper ore, in concentrations ranging from percent to ten times that amount, is mined from open pit or underground mines. The crushed mine ore is ground in rod and ball mills and then sent to flotation machines where the copper mineral rises to the top in a froth, making a copper concentrate of approximately 30 percent, 27 percent iron and 33 percent sulfur.
Copper | Geoscience Australia
Most of the copper ore produced in Australia comes from underground mines. At some Australian mines, the copper is leached from the ore to produce a copperrich solution that is later treated to recover the copper metal. The traditional method used at most mines involves the ore being broken and brought to the surface for crushing. The ore is then ground finely before the copperbearing ...
