The six main steps of iron ore processing

When iron ore is extracted from a mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening ... This step involves breaking up the iron ore to obtain an F 80 grind size before it can be ground. Once the ore has been crushed, it is diverted to a stockpile. The aim of this step is to ensure a smooth crushing ...

Iron Ore | The Canadian Encyclopedia

Iron ore usually consists of iron oxides and carbonates. Its most important mineral forms are magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe) and siderite (FeCO 3, 48.29% Fe). In Brazil, some ore that contains practically no other minerals can grade as high as 68% Fe, but the crude ore mined in Canada grades …
