Two ores A and B were taken. On heating ore A gives CO2 whereas, ore B

1.	Two ores A and B were taken. On heating ore A gives CO2 whereas, ore B gives SO2. What steps will you take to convert them into metals?
Answer» Since ore A gives CO₂ and ore B gives SO₂. Therefore, ores are MCO₃ and MS. A can be obtained as: \(MCO_3\overset{Calcination}\rightarrow MO + CO_2\) \(MO+C\overset{Reduction}\rightarrow M+CO\) B can be obtained as: \(2MS+3O_2\overset{Roasting}\rightarrow2MO+2SO_2\) \(MO +C\rightarrow M+CO\)

Answer»

Since ore A gives CO₂ and ore B gives SO₂.

Therefore, ores are MCO₃ and MS.

A can be obtained as:

\(MCO_3\overset{Calcination}\rightarrow MO + CO_2\)

\(MO+C\overset{Reduction}\rightarrow M+CO\)

B can be obtained as:

\(2MS+3O_2\overset{Roasting}\rightarrow2MO+2SO_2\)

\(MO +C\rightarrow M+CO\)
