Hiiii
The smell of rotten egg is given by sulphide ores only because the sulphur has the characteristic smell of rotten egg.
The sulphide ores are concentrated by froth floatation method.
The metals are obtained from the conc. ores by using pyrometallurgy, or smelting at high temperature

Hello mate,
● Answers -
(a) Sulphide ore -
- Smell of rotten eggs is given by H2S gas.
- Sulphide ores release H2S gas on HCl treatment.
(b) Roasting -
- Sulphide ores on heating in presence of air concentrates ore into metal oxide.
MS + O2 --> MO + SO2
(C) Reduction with carbon -
- Metal oxides are reduced to pure metal by heating with coke(carbon).
MO + C --> M + CO2
Hope this helped you..
