2017-11-10  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 (Luo et ...

Beneficiation of an iron ore fines by magnetization ...

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.
