Iron ore is typically classified as High grade (+65% Fe), Medium grade (+62 – 65% Fe) and Low grade (-62% Fe) by the content of Fe. Very low grade iron ore cannot be used in metallurgical plants. You will need the iron ore beneficiation plant to upgrade iron ore by increasing the iron content and reducing the gangue content.
Based on the physical and chemical properties of different minerals in the ore, ore crushing ground, gravity separation, flotation, magnetic separation, electrostatic separation method to separate the useful minerals and gangue minerals, and the various symbiotic of useful minerals as possible separated from each other, and to remove or reduce harmful impurities, to obtain the raw materials required for smelting or other industrial process.
According to the nature of the ore minerals, primarily mineral's physical, chemical or physical chemical properties, takes a different approach to separate the useful minerals and gangue minerals, make the various symbiotic useful mineral separated from each other as much as possible, to remove or reduce harmful impurities, the sorting process required to obtain smelting or other industrial raw materials.
The Beneficiation so useful components enrichment, reducing smelting or other processing of fuel, transport and consumption of low-grade ore poor can get economic use. Beneficiation test data obtained the main basis of the mineral deposit evaluation and building design. Other kinds of minerals from the gangue sometimes are elected separately from other minerals, metallic minerals or valuable machining methods.

3. Screenging and Classification
6. Mineral raw material crushing operations last-selected to do the job, so useful minerals and gangue separation or separated from each other to make a variety of useful minerals. This is the main body portion of the beneficiation. The sorting operation re-election, flotation,, A a electrostatic separation, A a pick and chemical elections and so on.
7. After the election, the product processing
8. Automatic control of the beneficiation process
The crushed iron ore passes to low intensity magnetic separator, and materials of high magnetic pass to cleaner flotation and thickener flotation. The pure product of flotation cleaner is iron ore concentrate, while the iron materials with low Fe content are moved back to rough flotation for further separation. The product after thickener flotation is grinded by ball millinto fine particles and moved to dehydration tank and then successively to high intensity magnetic separator and disc magnetic separator for further separation. Low content iron ore is moved back to thickener and very content iron ore is discharged as tailings.As a professional and the best mining machinery manufacturer in China, Hongxing Machinery is always ready to provide the superior mineral rotary kiln, mobile crushing plant, and these machines have the most competitive price and the most reliable quality so that they are the top choices for the high performance crushing equipment.
