copper metal is extracted from molten matte through bessemerization . the matte is introduced in to bessemer converter which uphold by tuyers. the air is blown through the molten matte. blast of air converts cu2s partly into cu2o which reacts with remaining cu2s to give molten copper.
copper is fairly abundant and has been used by man since prehistoric times for a wide variety of purposes. it was discovered and smelted from the oxidised ores to metallic copper by the primitive man. ores ores of copper are classified as: sulphide ores oxidized ores i chalcocite, cu2s i malachite, cuco3cu oh 2
chalcocite is an ore from which copper can be extracted for commercial use. the formula for this important ore is cu2s. in the laboratory it is formed by the following reaction: 2cu s cu2s the reaction takes place in laboratory conditions that allow the reactant atoms to move freely about in the reaction vessel.
during roasting the copper pyrite decomposes to cu2s and fes and the sulphur is oxidized to so2 gas. 2cufes2 o2 cu2s fes so2 arsenic and antimony present as impurities are removed in the form of their volatile oxides.

copper is found in the 1 oxidation state or cuprous form in its ores , so the sulfide ore of copper known as copper glance has molecular formula of cuprous sulphide cu2s . because copper is placed very low in the metal activity series , it is not much reactive and hence it can easily be roasted in the presence of air at high temperature to convert copper glance to copper oxide .

copper also occurs to a lesser extent in oxidized minerals carbonates, oxides, hydroxy-silicates, sulfates . copper metal is usually produced from these minerals by leaching, solvent extraction, and electrowinning. these processes are also used to treat chalcocite cu2s . the other 20% is obtained through hydro-metallurgy.

the principle ore of copper is copper pyrite and copper is extracted from this ore. the different steps in extraction of copper are: crushing and concentration: the ore obtained from mines are broken down into small piece by jaw crusher and then pulverized. the ore being sulphide ore is concentrated by froth floatation process. pulverized
the copper extracted from this process is mixed with the slag and is called matte copper due to its texture and appearance. this mainly consists of cu2s which is reduced to pure metal by blasting matte copper with air.
blast furnace for the extraction of copper blast furnace is a the furnace which is used in metallurgical process such as smelting to reduce industrial metals from its respective ore, generally iron.
