Copper Extraction. Copper is a reddish orange bright metallic substance that is an excellent conductor of heat and electricity. It can be drawn into pipes and it is resistant to corrosion. The most common found copper ore in nature is chalcopyrite which is a mixed ore of CuFeS 2. It contains only 0.5% Cu by mass.

· The extraction process involves the following steps: (i) Condensation of ore: Only 2≈3% Copper (Cu) is present in copper pyrites (CuFeS 2 ). After concentrating it by oil-froth floatation process, the amount of Cu will be 20≈30%. copper pyrites) and similar sulphide ores are the commonest ores of copper.
· Extraction of copper from copper pyrites involves the following steps – Crushing and concentration The ore is crushed and then concentrated by froth floatation process. The ore obtained from mines are broken down into little piece by jaw crusher and then pulverized. The ore being sulphide ore is concentrated by froth floatation procedure.
4. Beneficiation of Copper Ore. The next step in processing is called beneficiation. This is the first step in concentrating the copper into a more useable form. 5. Smelting and Extraction. The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution. 6.

· Traditional methods. Copper is usually sourced from copper-rich ores in two main methods; Copper can be smelted in a furnace by heating it with air to produce crude copper metal; for example, chalcocite is an ore of copper (I) sulfide, which reacts with oxygen to extract the copper: Cu 2 S (s) + O 2 (g) → 2Cu (s) + SO 2 (g) Copper ore can …

· Copper can be extracted from solutions of copper salts by electrolysis Displacement Copper can be extracted from solutions of copper salts by displacement using scrap iron, such as copper (II) sulfate with iron: CuSO4 (aq) + Fe(s) → Cu(s) + FeSO4 (aq), wherein the ionic equation is Cu 2+ (aq) + Fe(s) → Cu(s) + Fe 2+ (aq)
Copper is predominantly recovered from sulfide ores by pyrometallurgy – an energy intensive process requiring capture and treatment of released SO 2. Whilst some copper ores are amenable to hydrometallurgy, chalcopyrite, the main copper mineral, is challenging to process in aqueous solutions due to surface passivation.

· The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a …
Light the microburner and begin to heat the copper oxide in the tube. Keep heating for a minute or two and watch for changes occurring in the tube. When there are no more changes, stop heating, wait for a moment, and then try to light the gas coming out of well F1. Blow out the microburner and detach the lids from the Comboplate®.
Hydrometallurgy is usually suitable for low grade copper oxide, and the product of refined copper is called electrolytic copper. Modern hydrometallurgy methods usually can be separated as: the sulfating roasting- leaching- electrodeposition method; leaching- extraction- electrodeposition method; and bacterial leaching method.
There are many processes, it is mainly influenced by reasons below : 1. There are many kinds of sulfide copper ore, like Chalcopyrite, chalcocite, porphyry copper, copper blue, arsenopyrite . The reaction sequence with xanthate is Chalcocite> copper blue> speckle copper> pyrite 2. Secondary copper ore and oxidation influence 3.
· Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper (II) sulfate solution. Concentration of the copper (II) sulfate solution by solvent extraction.
Copper sulfide ore: copper content is minimal (about 2%-3%). 80% of copper in the world is refined from copper sulfide 2. Classified according to production process Copper concentrate: ore with high copper content before the smelting. Crude copper: the product resulting from copper concentrate being smelted, with a copper content of 95%－98%.
The main steps involved in the copper extraction method are as follows: Reduction of copper in chalcopyrite to copper sulfide Addition of calcium carbonate as a flux just like in blast …
