Iron ore beneficiation is really a complex process, it aims to remove the unwanted impurity materials or gangues, enhance the iron ore grade and refine the concentrate for final applications. This process involves various types of iron ore beneficiation plant and technology, including milling (crushing and grinding); washing; filtration; sorting; sizing; gravity concentration; magnetic separation; flotation; and agglomeration (pelletizing, sintering, briquetting, or nodulizing) etc. Most iron ore beneficiation operations will result in the production of three materials: a concentrate; a middling or very low-grade concentrate, which is either reprocessed (in modern plants) or stockpiled; and a tailing (waste), which is discarded or recycled for other application.

1. re-election law re-election method is based on the relative mineral density (usually called specific gravity) of the difference to sorting minerals. By different density mineral particles in the medium movement (water, air and heavy liquid) and the effects of various mechanical hydrodynamic forces, resulting in a suitable loose stratification and separation conditions, so that the mineral particles of different densities be separated.

2. flotation flotation method is based on the difference between physical and chemical properties of mineral surfaces by flotation reagent processing, the useful minerals selectively attached to the bubbles reach sorting purposes. Non-ferrous metal ore beneficiation, such as copper, lead, zinc, sulfur, molybdenum and other miners to use flotation processing; certain ferrous metals, rare metals and some non-metallic minerals, such as graphite ore, apatite, also with flotation France sorting.

3. magnetic separation method is the magnetic separation of magnetic minerals, depending on the different minerals subject to different forces in the magnetic field in the magnetic separator, whereby the sorting. It is mainly used for sorting ferrous metal ores (iron, manganese, chromium); also used for non-ferrous and rare metal ore sorting.

4. electrostatic separation method is electrostatic separation method for sorting according to the difference in mineral conductivity. When minerals by high-voltage electric field sorting machine, due to the different electrical conductivity of minerals, the role is different to static electricity on minerals, mineral and thus can be separated. Electrostatic separation method for precious metals, non-ferrous metals and non-metallic ore sorting. Concentrate mainly used for mixing coarse separation and selection; such as separation of scheelite and cassiterite; selection, selection of tantalum and niobium ore zircon and so on.
