 · The Haematite then reacts with Carbon in the cast iron to give pure iron and carbon monoxide gas. Fe 2 O 3 +3C→2Fe+3CO Limestone then creates the slag. Impurities such as S, Si pass into the slag and the slag later can be easily separated to yield pure iron. The iron minerals that are used as ores are hematite, magnetite, limonite, and siderite.

This, therefore, means that magnetic separation can be applied, in principle, to all fine iron-ore beneficiation plants. While flotation has a considerable capacity advantage over magnetic separation, the real advantage of magnetic separation over flotation, in fine iron ore beneficiation is that treatment of –10 µm iron. get price
