The purpose of the smelting process is to produce a metal from its original ore. this includes many types of base metals such as extracting iron from iron ore and copper from its ore. the process of smelting uses both heat and a chemical reduction agent. this process changes the oxidation state of the ore.
Smelting operations, where the original matte is broken down to yield metallic nickel and copper anodes. electro-refining operations, where these anodes are dissolved electrolytically to produce pure nickel and copper and an anode slime containing the precious metals. chemical operations, for the separation and refining of the individual metals.
The gold smelting process. gold from such sources must undergo another smelting process to remove impurities before it is used to make a new item. refining gold . smelting is not always the final stage in gold extraction. depending on the intended use of the gold, it may have to be refined before being put to use.

The product of melted sulfides is called a matte, and is highly corrosive liquid. converting that molten sulfide matte to metal is called smelting. small scale smelting can be done in a crucible in fact that is what a fire assay is. when smelting assays are done on high sulfide ores, a couple of iron nails are added to the mix.
