【Process Introduction】：Scheelite dressing can use gravity, magnetic and flotation separation. The types and properties of the ore decide the separation methods and processes. Basing on good floatability of scheelite, the flotation is selected.
【Application Scope】：Scheelite flotation product line is suitable for the scheelite containing multi metals with complex structure.
Concentration pulp with high temperature is common method. First, the pulp is concentrated to 60%-70%; the next, sodium silicate is added into pulp; then, the pulp is heated to 80℃ and stirred for 30-60min; the last, it is diluted with water. The floatation of scheelite is under the room temperature, and the product in tank is calcspar & fluorite.
It is difficult to separate scheelite and barite by sodium silicate because of the closed inhibitory action for scheelite and barite. We choose alkyl sulfate as collector to repeatly select barite under the 1.5-3PH, and the product in tank is scheelite.
Xanthate is used to capture sulfide minerals in scheelite floatation. We add a little oxide and sodium sulfide to inhibit sulfide without floatation.
Oleic acid as collector and sodium silicate as inhibitors could inhibit the quartz and silicate gangue and float scheelite.
An air inflation mechanical agitation Flotation Cell with slurry suction（as suction cell of KYF flotation cell).
A ceramic filter which relies on microporous ceramics for vacuum dewatering.
A single-rotor ring hammer crusher for processing low-hardness and brittle materials.
The High-Efficiency Agitation Tank is a mixing equipment that forces the slurry to circulate up and down in the tank.
