Two ores A and B were taken. On heating, ore A gives `CO_(2)` whereas, ore B gives `SO_(2)`. What steps will you take to convert them into metals ?

Text Solution

Verified by Experts

Since ore A gives `CO_2` and ore B gives `SO_2`. Therefore, ores are `MCO_3 and MS`.
As A is a carbonate ore, it is first subjected to calcination followed by reduction.
`MCO_3to^(Calci nation) MO+CO_2`
`MO+C to^(Reduction )M+CO`
As B is a sulphide ore, it is first subjected to roasting followed by reduction.
`2MS+3O_2 to^(Roas ti ng)2MO+2SO_2`
`MO+C to^(Reduction )M+CO`
