The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores. Chalcopyrite (also known as copper pyrites) and similar sulphide ores are the commonest ores of copper.
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite (CuFeS2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
Copper extraction refers to the methods used to obtag copper from its ores. The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country dependg on the ore source, local environmental regulations, and other factors.
The method used to extract metals from the ore which they are found depends on their reactivity. For example, reactive metals such as alumium are extracted by electrolysis, while a less-reactive metal such as iron may be extracted by reduction with carbon or carbon monoxide.
The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. The oxidized ores, consistg of the silicates, carbonates and sulfates, are treated by several methods, all volvg some form of leachg of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.
Copper can be extracted from its ore by heatg it with carbon. Impure copper is purified by electrolysis which the anode is impure copper, the cathode is pure copper, and the electrolyte is copper sulphate solution. An alloy is a mixture of two elements, one of which is a metal.
Extraction and purification of copper Copper is less reactive than carbon, so it can be extracted from its ores by heatg it with carbon For example, copper is bbc co uk schools gcsebitesize science ocr_gateway_pre_2011 2
Copper processg, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals society.
Copper, t, lead, and iron are more reactive and must be heated with carbon to extract the metals. Alumum, calcium, sodium and other active metals are extracted usg electrolysis. Copper can be extracted from its ores by reduction.

About 80% of all copper extracted comes from sulphide ores. A typical ore contas only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extractg it from such small concentrations. The ore is a mixture of merals and rock (called gangue). The most common copper merals are:

Extraction: An ore has to be changed chemically to the metal. This process is called reduction. How this is done, and how much it costs, depends upon the metal's reactivity (see reactivity properties). In general, the more reactive the metal, the harder it is to extract it from its ore.
Metal extraction from ores occurs many different ways volvg physical, chemical and electrical means. Even ores of the same metal sometimes require different methods of separation dependg on the concentration of the metal and its chemical composition with the ore. Contue Readg

Cobalt extraction refers to the techniques used to extract cobalt from its ores and other compound ores. Several methods exist for the separation of cobalt from copper and nickel. They depend on the concentration of cobalt and the exact composition of the used ore.
Many metals are impure when they are extracted from their ores. Impurities have to be removed. Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell.

From an environmental pot of view, the old tailgs piles are a major contributor to water pollution. Many copper ores conta sulfides, which, mixed with water become strongly acidic.

Most of the copper ores med the United States conta only about 1.2-1.6% copper by weight. The most common sulfide ore is chalcopyrite, CuFeS 2 , also known as copper pyrite or yellow copper ore.
