20201027 · Unlike the high-grade hematite ores which are easily processed into saleable iron products, through crushing, grinding or milling, concentration by screening, and/or using hydraulic or magnetic classification [2], magnetite ores require extensive beneficiation to produce iron concentrates.
view more20221027 · Rough processing of iron ore employs dry methods which means that equipment is tuned to process large particles, but fine magnetic material less than a few tenths of a millimeter in size is not separated as efficiently. The relevance of this study is determined by the fact that dry beneficiation waste contains recoverable iron-bearing …

According to the above beneficiation method, the magnetite with complex compositions also needs gravity separation, flotation, calcination, and other methods. For example: High sulfur magnetite: weak magnetic separation - flotation. Hematite/siderite - magnetite: magnetization …

The ore composition is simple, and the weak magnetic separation process is often used: When the grinding particle size is more than 0.2mm, most iron ore magnetic separation plants often adopt a one-stage grinding – magnetic ...
view moreDry high-intensity separation is largely restricted to ores containing little, if any, material finer than about 75 μm. The effectiveness of separation on such fine material is severely reduced by the effects of air currents, particle–particle adhesion, and particle–rotor adhesion.
