The principal 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.

The early development of copper probably was most advanced in Egypt.As early as 5000 bce, copper weapons and implements were left in graves for the use of the dead.. Definite records have been found of the working of copper mines on the Sinai Peninsula about 3800 bce, and the discovery of crucibles at these mines indicates that the art of extracting the metal included some r

The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.

Copper is obtained from sulfide ores through a two-step process consisting of roasting the ore in the presence of oxygen and heating the resultant copper (1) oxide with powdered carbon.
ChatThe smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example: FeO(s) + SiO 2 (s) FeO.SiO 2 (slag) This is very similar to the removal of impurities in the blast furnace.

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.

The process. The concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate and air or oxygen in a furnace or series of furnaces. The copper (II) ions in the chalcopyrite are reduced to copper (I) sulphide (which is reduced further to copper metal in the final stage).

Copper is a metal that is present low in the reactivity series. It mainly occurs in nature in the form of sulphide ore which can be converted into the corresponding oxide simply by heating in the absence of air, a process known as roasting.

Copper is obtained from sulfide ores through a two-step process consisting of roasting the ore in the presence of oxygen and heating the resultant copper(l) oxide with powdered carbon. The overall reaction is as follows: * 2Cu2S (s) + 302 (g) + 2C (s) 2SO2 (g) + 4Cu (s) + 2CO (g) Calculate the maximum yield of copper obtained from 1.60 kg of CuzS.

Copper is obtained by smelting process from its ore in which its ores are heated in the furnace and then impure copper obtained are purified via reduction and electrolysis. The most common extraction is from its sulphide ores like chalcopyrites CuFeS 2 and Copper(II) sulphide (CuS) via roasting in presence of enrich oxygen and flash smelting as:
