Extraction Of Copper From Sulphide Ore

Copper Mining and Extraction Sulfide Ores. About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon These mines have now closed and today the biggest copper mines are in Chile (ndida mine) and Indonesia (Grasberg mine) These produce many millions of tonnes of copper ore per year The main ores of copper are sulfides and

ore dressing copper extracted from ores

Copper Mining and Extraction Sulfide Ores. Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers.

Copper Mining and Extraction: Oxide Ores

Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (1114), but is introduced here because an important by-product of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching. The ...

Innovations: Introduction to Copper: Mining & Extraction

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 extracted from sulphide ore using the method:

The copper can be extracted from its sulphide ore by the auto reduction process. The ore is reduced by heat alone. The copper and the oxygen have been reduced (decrease in oxidation state). The sulphur has been oxidised (increase in oxidation state). The reducing agent is the sulphide ion in the copper (I) sulphide.

Copper Smelting Chemistry Tutorial

Copper can be extracted from sulfide ores (usually higher grade ores) by direct smelting. The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC. Copper can be extracted from oxide ores using electrolysis ( electrowinning ) for low grade ores, or by the carbon reduction method of smelting for higher ...

Copper Mining and Extraction Sulfide Ores

The 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.

EXTRACTING METALS FROM SULFIDE ORES

Electrowinning has become the exclusive choice for recovering copper following leaching of oxide or sulfide ores and solvent extraction. SX/EW produced more than 3.3 million tonnes of copper in 2009, which is 21% of total world copper production.

copper extraction from sulphure ores | Phactorize

Copper extraction - Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

The Extraction of Copper - Chemistry LibreTexts

Extracting of Copper from Other Ores. 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.

In the extraction of copper from its Sulphide Ore, when ore is subjected to roasting some of it is oxidised to Cu 2 O which reacts with the remaining Cu 2 S to give copper metal. In this process, Cu 2 S behaves as reducing agent. 2Cu 2 S+3O 2 +heat2Cu 2 O(s)+2SO 2 (g) 2Cu 2 O+Cu 2 S+heat 6Cu(s)+SO 2 (g)
