Copper Mining and Extraction Sulfide Ores

The blister copper produced by this process is 99% pure copper. The name ‘blister’ copper comes from the fact that this final process produces bubbles of sulfur dioxide on the surface of the copper. The blister copper is cast into anodes ready for electrolytic refining. The anode casting turntable moves slowly round.

Copper Mining and Production Processes Explained

First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).

Extraction of Copper from Copper pyrite Grade 12 Science

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 ore is kept in water containing pine oil and the mixture is agitated by passing compressed air.

How is copper extracted from its Sulphide ore ? Explain

2018-6-29  In the extraction of copper from its Sulphide Ore, when ore is subjected to roasting some of it is oxidised to Cu2O which reacts with the remaining Cu2S to give copper metal. In this process, Cu2S behaves as reducing agent. 2Cu2S+3O2+heat→2Cu2O

2021-7-19  The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
