2015-1-1 · Oxidized iron ores are much more difficult to upgrade by magnetic separators, because their magnetic susceptibilities are only about 1% or less of that of magnetite. In oxidized iron ore separation, it is therefore important to create magnetic fields with high intensities and high gradients to achieve higher iron recoveries. 9.3.2.1.

2021-11-9 · An ore is a mineral deposit that contains a metal that can be extracted using existing technological methods. Iron can be extracted from two types of iron ores: Magnetite and hematite. Magnetite is composed of iron in the form of Fe 3 O 4. Hematite is a mineral that contains iron in the form of Fe 2 O 3.

2021-12-13 · There are two main types of minerals in iron ore deposits sold in the commercial seaborne iron ore market. The first is hematite, which has high in-situ grades of high 50s to mid 60s in iron content, and is the cheapest to develop and operate at large scale, making it the mainstay of the current iron ore market. The second is magnetite.
