(JEE MAIN-2021)
Solution
$(a)$ Concentration of $\mathrm{Ag}$ is performed by leaching with dilute $\mathrm{NaCN}$ solution
$(b)$ Pig iron is formed in blast furnace
$(c)$ Blister Cu is produced in Bessemer converter
$(d)$ Froth floatation method is used for sulphide ores.
Note : During extraction of $Cu$ reverberatory furnace is involved.
