Hematite is also known as red iron ore. The chemical formula of it is Fe2O3. Hematite is a kind of weak-magnetic iron ore. The floatability of hematite is better than that of magnetite. Therefore, it is the main material for iron-making. The main hematite beneficiation processes are gravity separation, flotation, high-intensity magnetic separation, and weak-magnetic separation, or a combination of a variety of beneficiation processes.
The beneficiation of hematite used to be gravity separation process in the early time. It mainly contains jigging machines, centrifugal separators, spiral chutes, spiral separators, shaking tables, and so on. Its processing capacity is not so good. The grade of the ore processed is low. And its recycling rate is low.
Later, there are hematite flotation process and hematite high-intensity magnetic separation process. The collector of the flotation process is mainly paraffin soap oxidated. And the separating equipment of the high-intensity magnetic separation process is the high-intensity magnetic separator. But the separating technology can not meet the satisfaction.
In recent years, the hematite beneficiation has gotten a great progress. Its main beneficiation processes are the high-intensity magnetic separation process with high-gradient electromagnetic pulsating magnetic separators and the reverse flotation separation process. The combination process of the high-intensity magnetic separation and the flotation separation can turn the hematite to iron concentrate. And the recycling rate of iron concentrate can reach the satisfaction indicators.
