Process water is used to assist the separation process. The heaviest particles are separated from finer particles by centrifugal force. A collector at the bottom of each spiral collects the heavy concentrate (so-called hematite concentrate) and eliminates the lighter unwanted particles (middlings and tails).

Iron Ore Statistics and Information. Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel ...

Answer (1 of 2): Hematite ore is simply mined, crushed, and after that screened into either lump or fines. It is then immediately sold as such. The ore has high iron content, typically between 56% and 64% Fe. Magnetite has higher iron content than hematite. But hematite ore usually contains larg...

Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.

The per cent of iron in the ore as mined must be not less than 50%, if it is to be used without being first improved (beneficiated) by cobbing, washing, calcining, or magnetic concentration. Leaner ore is found in very large quantities; and in a favorable situation, it may be workable by some concentrating process. Hematite
