  • Hematite | LOAAC Wikia | Fandom

    Hematite is an ore for making iron. It is a reddish color, due to the iron oxide. You can smelt it down in a blast furnace with coke and limestone to produce pig iron. Another iron, wrought iron, is produced by firing hematite and charcoal in a bloomery with low temperatures so that it does not melt. Then, you take out the bloom and remove the slag. Repeat the process until it is free of .
