Which ore is mainly used in the extraction of copper?

Chalcopyrite
The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS2) also known as Copper Pyrites and other such sulphides.

Which method is used for Cu extraction from its ore?

Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. The copper produced by this process is 99.99\% pure copper.

What are the two ore of copper?

There are two main copper ore types of interest, copper oxide ores and copper sulfide ores. Both ore types can be economically mined, however, the most common source of copper ore is the sulfide ore mineral chalcopyrite, which accounts for about 50 percent of copper production.

How is copper extracted from sulphide ore?

Answer: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.

What is copper ore used for?

Most copper mined today is used to conduct electricity – mostly as wiring. It is also an excellent conductor of heat and is used in cooking utensils, heat sinks, and heat exchangers. Large amounts are also used to make alloys such as brass (copper and zinc) and bronze (copper, tin, and zinc).

What ore is copper made from?

Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature….Ores.

How is copper extracted from copper pyrite?

After roasting, the ore is mixed with silica and coke and then smelted in a blast furnace. The matte obtained from the blast furnace is charged into a silica lined converter.
