Hematite is a weakly magnetic iron ore, which is mainly divided into single hematite, mixed ores containing polymetallic hematite and magnetite and hematite.
Mineral processing technology：
Single Hematite
1.Magnetization roasting and magnetic separation
Roasting magnetic separation is one of the effective methods to select fine to fine particles (less than 0.02mm) hematite. When the mineral composition is relatively complex and it is difficult to obtain good beneficiation indicators by other mineral processing processes, the magnetization roasting magnetic separation method is often used.
2.Gravity separation, flotation, strong magnetic separation and their combined processes
Flotation is one of the common methods for selecting fine-grained to fine-grained hematite ore, and it is divided into forward flotation and reverse flotation. Gravity separation and strong magnetic separation are mainly used to separate coarse-grained (2-20mm) and medium-grained hematite ores.
Polymetallic hematite ore
It is mainly hydrothermal and sedimentary phosphorus- or sulfide-containing hematite and siderite ore. This type of ore generally uses gravity separation, flotation, strong magnetic separation or other combined processes to recover iron minerals, and flotation to recover phosphorus or sulfide.
Magnetite-erythrite ore mixed mineral processing method and process flow
1.Single magnetite-red (rhombohedral) iron ore
There are two commonly used beneficiation methods for this type of ore: one is a combined process of weak magnetic separation and gravity separation, flotation, and strong magnetic separation. Magnetite is recovered by weak magnetic separation, and weak magnetic separation is recovered by gravity separation, flotation, and strong magnetic separation. Magnetic iron ore. The second is a combined process of magnetization roasting, magnetic separation or other mineral processing methods.
2.Polymetallic magnet-red (rhombohedral) iron ore
The beneficiation method of this type of ore is the most complex among iron ores. Generally, a combined process of weak magnetic separation and other mineral processing methods is used.
The application of mineral processing methods and their combined processes varies with ore type. Welcome to contact online customer service to obtain production line configuration.
