Refining (metallurgy) - Wikipedia

This process oxidised the silicon to form a slag, which floated on the iron and was removed by lowering a dam at the end of the trough. The product of this process was a white metal, known as finers metal or refined iron. Precious metals. Precious metal refining is the separation of precious metals from noble-metalliferous materials.
