The separation efficiency of magnetite ore is improved by separating qualified magnetite concentrate and tailing adopting weak magnetic separation at a coarser grinding fineness and regrinding the interlocking particles of magnetite by selectively classification.

The Introduction of Magnetite Ore Beneficiation

At present, the domestic magnetite ore beneficiation processing line is mainly used to beneficiate the low grade “Anshan style” magnetite ore. In domestic, most concentration plant adopts the stage grinding and multiple stage grinding. When the ore is coarse-disseminated, the first stage grinding is adopted.

Magnetite Separation Production Line Xinhai

Strong magnetic iron ore separation process. It is used to low grade magnetite. Due to the strong magnetic and easy to grind, one stage grinding is adopted for magnetite with coarse particle distribution, conversely the multi stages grinding. At present the fine grinding technology promoted by Xinhai improves the concentrate grate from 61% to 67%.
