Among following compounds, the number of those present in copper matte is ___ .
\(CuCO _3\)
\(Cu _2 S\)
\(Cu _2 O\)
\(FeO\)
Show Hint
Remember the composition of copper matte. It is mainly Cu2S and FeS.
Correct Answer: 3
Solution and Explanation
Copper matte is a molten mixture primarily composed of Cu2S and FeS. It is an intermediate product in the smelting of copper ore. Of the given compounds, only Cu2S is present in copper matte.

What are Ores and Minerals?
Minerals are the naturally occurring, homogeneous inorganic solid substances. They are having a definite chemical composition and crystalline structure, hardness and color. For example, copper pyrite, calamine, etc.
Impurities in an ore are called gauge. The removal of a gauge from the ore is called concentration ore.
Several steps are involved in the extraction of pure metal from ores. Major steps are as follows –
- Concentration of the ore
- Isolation of the metal from its concentrated ore
- Purification of the metal
