Among following compounds, the number of those present in copper matte is ___________.
A. $$\mathrm{CuCO_{3}}$$
B. $$\mathrm{Cu_{2}S}$$
C. $$\mathrm{Cu_{2}O}$$
D. $$\mathrm{FeO}$$
Answer
1
Explanation
Copper matte is a mixture of copper sulfide and iron sulfide formed as a result of smelting of copper ore. It contains mainly copper sulfide (Cu2S) as the major component and iron sulfide (FeS) as a minor component.
The compounds A. CuCO3, C. Cu2O, and D. FeO are not present in copper matte, but can be formed as a result of further processing or refining of the matte.
Therefore, among the given compounds, only "B. Cu2S" is present in copper matte.
