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?

Answer»

SOLUTION :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`
