Process Introduction:
Magnetic separation is one of the main methods for iron ore separation. Magnetic separation is divided into weak magnetic separation and strong magnetic separation. Weak magnetic separation is mainly used for the separation of ferromagnetic iron minerals such as magnetite. vanadium-titanium magnetite. Strong magnetic separation is mainly used for the separation of hematite-based weak magnetic minerals. Some magnesite and limonite also use strong magnetic separation equipment. Simple tail throws resume geological grade sales to improve grade simply and sale.
Iron ore is a mineral aggregate containing iron elements or iron compounds that can be economically utilized. Any ore containing economically available iron is called iron ore.
There are many kinds of iron ores. The main 4 types of iron ores are Magnetite (Fe3O4), Hematite (Fe2O3), Limonite(Fe2O3．nH2O), and Siderite (FeCO3). According to the different properties of iron ores, their beneficiation methods are also different.
The iron ore dressing process is aimed at the processing of iron ore materials, which is divided into crushing and screening, grinding and classification, separation, and dehydration. Crushing and screening refers to the crushing and screening of iron ore to ensure that the particle size of crushed ore can provide ore that meets the requirements of block size for the next process flow. Through the treatment of ball mill and classifier, the ore conforms to the requirements before mineral separation is obtained. Mineral separation generally includes gravity separation, flotation, and magnetic separation. Generally, iron ore can use the separation process according to the nature of iron. Dehydration is to concentrate, filter and dry the ore after mineral separation, and finally select the iron ore.
