Compare the Coarse and Fine Function of Flotation Separator

Flotation machine (also called flotation separator) is applicable for the separation of nonferrous metal, ferrous metal and nonmetal, such as fluorite and talc. Flotation concentrator is commonly used ore flotation equipment in the ore dressing plants and plays a crucial role in the fast development of mining industry in China.

On the premise of ore grain monomer dissociation, coarse grinding flotation can save the grinding cost, reduce the processing cost. In dealing with the uneven disseminated ores and large porphyry copper mine, under the premise that ensure the roughing recovery, has a tendency to after coarse grinding flotation. However, due to the coarser particles are heavier, not easy to float in the flotation-cell, probability of collisions with bubbles is reduced, the adhesion after bubble because of peeling strength, easy to fall off. Therefore, coarse particles in the general process conditions, the flotation effect is poorer, in order to improve coarse flotation, can adopt the following special process conditions.

Practice proved that the mechanical agitation type flotation machine pulp in strong turbulent motion, is the main factor of ore grain fell off the bubble. Therefore, reduce the pulp movement for the turbulence intensity of coarse flotation is the fundamental measures.

1. Add a pulp density appropriately, improve reagent regime: selects the collecting power collector and reasonable drug concentration increased, the purpose is to enhance the mineral and the fixation strength of the bubble, speed up the rose, in addition to adding non-polar oil. Auxiliary collector, such as diesel, kerosene can 'consolidate' surrounding the three-phase contact, enhance the fixation strength of mineral with bubbles.

2. Choose the special suitable for the flotation of coarse flotation separator, etc.To improve and adjust the structure and operation of conventional flotation separator, decrease the groove depth (use shallow trough type), shorten mineralized bubbles float up, in order to avoid ore grain fall off, above the impeller area to add grizzly pulp turbulent intensity, maintain smooth bubble area, increase your, form more big bubble, is advantageous to the formation of bubbles and particles float, the coarse grain 'arch lift' rise, quickly and smoothly when you blow a bubble.
