Flotation separator not only requires minerals flotation monomer dissociation in full, and requires the inclusion of appropriate granularity. Ore grain is too thick, even if the mineral has monomer dissociation, because more than bubbles floating load ability often can"t afford to float. All kinds of different ore flotation equipment granularity limit, such as sulfide minerals generally 0.2 to 0.25 mm, the sulfide minerals of 0.25-0.25 mm, for some of the smaller non-metallic mineral density such as coal, grain size limit can also be improved. However, grind size carefully (such as less than 0.01 mm) is also bad for flotation. Practice proves that the flotation behavior of various granularities is distinct. Different minerals have the optimal size range of flotation separator.Practice proved that the mechanical agitation type ore flotation equipment 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. Choose the special suitable for the flotation of coarse flotation separator, etc. To improve and adjust the structure and operation of conventional flotation cell, 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.2. 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...
