Due to the disadvantages of complex process flow, large equipment investment and high beneficiation cost, these processes are difficult to be adopted for some small and medium-sized hematite mines, especially those mixed with hematite and magnetite. There are few large hematite mines in China, while there are many small and medium-sized ...

1. Introduction. Hematite (α-Fe 2 O 3) is widely distributed in various rocks and is one of the most common and abundant iron oxide minerals in soil (Zhang, 2007).However, it cannot be used in iron and steel industry without preliminary beneficiation due to its low grade. Many researchers have investigated the separation of iron minerals from gangue minerals by froth flotation process …

Beneficiation of hematite iron ore. Also known as red hematite ore of its chemical formula is Fe2O3, which is a weakly magnetic iron minerals, magnetite floatability than good, one of the main raw material is iron. The main mineral processing technology have re-election, and strong magnetic separation or flotation process and use a variety of ...

The beneficiation of a hematite ore fines with magnetization roasting and magnetic separation was proposed and studied. The magnetic properties of ore can be enhanced due to the selective conversion of hematite and siderite into magnetite. Magnetization roasting can be applied effectively for the processing of carbonate-containing hematite ore.

front It is said that hematite accounts for a considerable proportion in China's iron ore resources. Compared with magnetite, most hematite has fine embedded particle size, large mud content and great difficulty in beneficiation. Therefore, since the sixth five year plan, China has regarded hematite as a national scientific research project and achieved fruitful results. ...
