Metallurgic Processes | Boundless Chemistry

The pig iron was melted in a running-out furnace and then run out into a trough. This process oxidized 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.
