The ore dressing method of this type of ore is more complicated in iron ore beneficiation. Generally, the combined process of weak magnetic separation and other methods is adopted, that is, magnetite is recovered by weak magnetic separation recover weak magnetic materials by gravity selection, flotation or strong magnetic separation.
Iron ore is beneficiated using separation steps based on mineral composition without the use of separation steps based entirely on size. In a preferred sequence of steps the iron ore is passed from a ball mill through a magnetic separator where low iron content tailings are rejected and the concentrate passed to a flotation step, where a high iron content concentrate froth is made

There are many mineral processing methods, and there are two commonly used methods (1). Roasting magnetic separation Roasting magnetic separation is one of the effective methods to separate fine to fine ( 0.02mm) weakly magnetic iron ore. When the minerals in ore are complex and it is difficult to get good indexes by other methods, magnetization roasting magnetic
Oct 01, 2014 The beneficiation process can be defined as a treatment process of ore which results in a more concentrated form of the product. It is often used in the preparation of iron ore for smelting. This is an essential process as it helps improve the yield from a deposit of ore, thereby increasing the potential profits that can be obtained from the ...
Apr 06, 2021 The objectives of this research were twofold (1) To devise a mineral-dressing method whereby the yield from currently mined east Texas iron ores might be increased and the grade improved, and (2) to extend such treatment to include the lower grade ferruginous materials that are not amenable to beneficiation by simple washing and, therefore ...
