Detailed Solution:(A) Concentration of Ag & Au done by NaCN. It is known as Mac Arthur Process (cyanide process)
(B) Blast furnace produces pig Fe.
(C) Blister Cu → Reverberatory furnace. In this furnace smelting & roasting of ore take place
CuFeS? + O? → Cu? O + FeO
(D) Froth floatation process is used for concentration of sulphide ores.
