Iron ore beneficiation plant equipment and processes for all purposes are to improve the quality of iron ore concentrate, but in order to improve the quality of fine iron ore is very complex, but in general factors affecting iron ore flotation concentrate grade It is mainly divided into the degree of ore decomposition, the agent used in flotation, and the concentration of flotation. These three aspects are the most important.

In terms of the degree of ore decomposition, the degree of ore decomposition refers to the degree of ore crushing. The size of the finished product will increase the difficulty of sorting and increase the cost of ore dressing. Therefore, the crushed ore can use a fine crusher or increase the grinding ball in the ball mill to improve The target mineral monomer dissociation degree.

The choice of iron ore flotation agent, according to which the mineral constituents are determined, some component and iron component floatability similar purposes, or impact grade iron ore concentrate, particularly the selection of collector, the collector Poor selectivity or expiration, insufficient dosage or improper selection or improper use of medium regulators. The adjustment method is to choose the appropriate pharmaceutical system.

Flotation concentration means that if the concentration of iron ore flotation slurry is too large, or if the foam level is too low or too high, the foam layer will be too thick or too thin to affect the grade of refined iron ore. It is necessary to appropriately reduce the concentration of the slurry and appropriate Increase or decrease the liquid level in the tank.
