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?
Answers
Ore A gives CO2 so ore A is Carbonate ore while B gives SO2 hence B is Sulphide ore.
Therefore, Calcenation is done for ore A and Roasting for ore B.
Hope it helped.
Explanation:
Calcination is the process of strongly heating the ore into oxide in limited supply of air. This is used to convert metal carbonates an hydroxides into their respective oxides.
Roasting is the process of strongly heating the ore into oxide in unlimited supply of air.This process is commonly used fro sulfides ores.
Ore-a gives carbon dioxide which means that it is a carbonate ore. So, by calcination followed by reduction of oxide in the presence of carbon will give us metal.
Ore-b gives sulfur dioxide which means that it is a sulfide ore. So, by roasting followed by reduction of oxide in the presence of carbon will give us metal.
