Identification:
Ore A – Carbonate ore
Steps to convert carbonate ore into metal:
1. Calcination – Metal oxide is obtained by heating the ore in the presence of oxygen.
Reaction Involved: ACO3ā AO+ CO2
2. Reduction – Metal is obtained by the reduction of metal oxide with coke.
Reaction Involved: AO+Cā A+ CO
Identification:
Ore B – Sulphide ore
Steps to convert sulphide ore into metal:
1. Roasting – Metal oxide is obtained by the heating of the ore in the presence of oxygen.
Reaction Involved: 2BS+3O2ā 2BO+2SO2
2. Reduction ā With Carbon, reduction of metal oxide to metal occurs.
Reaction Involved: BO+Cā B+CO
