The Sulfide Process is a method used in metallurgy to extract metals from their ores, particularly for sulfide minerals. This process typically involves crushing the ore and then concentrating it through flotation, where sulfide minerals are separated from waste materials. The concentrated ore is then subjected to smelting, where it is heated with a flux to produce a metal and slag. After smelting, the metal can undergo further refining to remove impurities. The Sulfide Process is commonly used for extracting metals like copper, nickel, and zinc, making it an essential technique in the mining and metallurgical industries.
