How to Smelt Iron The 6 Steps to Iron Smelting The

Iron ore can be bought or gathered, but for the sake of demonstration, we gathered the ore ourselves. The best time to collect iron ore is in the winter because the ocean is more active. Active waves separate the black, magnetic sand from lighter silica sand. This magnetic sand is an iron ore called magnetite, which when combined with carbon ...

Steelmaking and Refining Introduction to Chemistry

Steelmaking and Refining Introduction to 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.
