In order to extract copper from malachite, the malachite must be heated to a high temperature. This produces a fine black powder (copper Oxide). The copper oxide is heated again to a more extreme temperature, this removes the oxygen, leaving metallic copper.

What are the ores in copper?
Any deposit of rock or mineral, such as malachite, that has a content of copper high enough to make it economically feasible to mine.
How does malachite react with sulphuric acid?
Sulphuric acid is used with malachite to separate the copper and the sand. This is because the copper dissolves into the solution where as the sand remains.
What chemicals form when malachite heated?
The formula for Malachite is Cu 2 CO 3(OH) 2.
What is the name of the copper compound found in malachite?
According to my chemistry book it's copper carbonate.
Malachite is naturally occurring from copper carbonate. outline how a sample of copper metal could be obtained from large lumps of malachite in the laboratory?
Malachite is a hydrated copper carbonate - Cu2CO3(OH)2; this compound is thermally decomposed in water, carbon dioxide and cupric oxide.Cupric oxixe may be reduced with hydrogen to copper:CuO + H2 = Cu + H2O
