Refining (metallurgy) - Wikipedia
The pig iron was melted in a running out furnace and then run out into a trough. 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

How to Use Bleach on Gold Ore to Remove Gold | Sciencing
Apr 24, 2017 · Gold is an almost non-reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.
Metal Types and Recycling Process
Mar 05, 2021 · Steel and iron are the most recycled materials in the world due in part to the opportunity to recover large structures as well as the ease of reprocessing.
