The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( C u F e S 2 ) are converted to copper by a different method from silie, carbonate or sulfate ores.
Copper is typically extracted from oxide and sulfide ores that contain between and percent copper. The refining techniques employed by copper producers depend on the ore type, as well as other economic and environmental factors. Currently, about 80 percent of global copper production is extracted from sulfide sources.

The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridges. Ores consist of the desired metal compound and the impurities and earthly substances called Gangue. The extraction of metals and its isolation occurs over a few major steps:
XSM stone crushing machine projectsulphide ore extraction process to copper product. ShangHai XSM (sulphide ore extraction process to copper product) are a professional production of stone crushing and Widely used in Europe, South America, Africa, East Asia and Asia region.
Metals that require a moderate amount of energy to extract, that is, those that can be extracted by heating their ores, were the next to be used widely. Highly reactive metals requiring huge amounts of energy to extract have only been used in more modern times.
Copper ore divides into ore sulfide,ore oxide and mixing ore according to its oxide rate . The main process for copper ore is flotation, for refractory mixed copper ore and refractory oxide ore, normally use hydrometallurgy process .It is a high technological enterprise that integrated research, manufacture, sales and service .
How are metals extracted from mineral ores? How do we make iron, steel, other alloys, aluminium, sodium, copper, zinc, titanium and chromium. The six linked pages include an introduction to metal extraction or metal manufacture and production. There are detailed notes on the extraction of iron and its conversion to steel.
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 "recovery efficiency," with a typical mining operation requiring about 20 million Btu/ton of hode copper produced.

Extraction of Copper. The chief and important ore of copper from which the metal is most isolated is copper pyrites (CuFeS 2). Froth floatation process is used for concentrating the ore. The powdered ore is suspended in water and .
