However, for fine-grained wolframite or wolframite tailings, gravity separation cannot achieve a good recovery rate (only about 40%). The flotation method is an effective method for the separation of fine-grained materials, and the same is true for wolframite ore. The commonly used micro-particle wolframite ore flotation method Mainly include: selective flocculation-flotation method, carrier flotation method, and microbubble flotation method.
Selective flocculation -The purpose of the flotation process is to recover wolframite ore from the black tungsten fine mud suspension system. Add a dispersant to make all the ore particles disperse stably and evenly in the slurry, and then add a selective flocculant to selectively make the wolframite The ore flocculates and agglomerates, while the gangue minerals are still in a dispersed state. Finally, a wolframite collector is added to recover the wolframite in the fine mud by flotation. The key to the quality of the sorting index of this process lies in the selection of dispersant and flocculant. The advantages of the process are simple process, thorough separation, and easy industrialization. The disadvantage of the process is that it is easily affected by water-soluble ions, making the flocculation effect difficult to control.
Carrier flotation is also called piggyback flotation. The principle is the same as that of selective flocculation, which involves increasing the particle size of flotation materials, adding coarse particles with relatively good floatability as carriers, and causing the fine-grained minerals and coarse particles in the tungsten fine mud to collide with each other under the action of appropriate chemicals. Hydrophobic agglomerates are formed and then separated by conventional flotation method.
The generally used coarse-grained carrier for black tungsten fine mud carrier flotation is coarse-grained wolframite. The advantage is that it avoids the difficulty of separating coarse-grained materials from fine-grained wolframite. Its disadvantages are: Increased collector consumption. The sorting process of the carrier flotation process is similar to conventional flotation. It can only improve the sorting effect of fine-grained minerals, but it is difficult to fundamentally improve the flotation indicators of fine-grained minerals.
Microbubble flotation process is suitable for all fine particle sizes The process of mineral sorting can also increase the flotation speed. Microbubble flotation uses microbubble aerator flotation equipment that can produce large aeration volume and small diameter to improve the recovery rate of fine-grained minerals, supplemented by foam flushing water to improve grade. To achieve the purpose of better flotation of fine-grained minerals.
The above is an introduction to the flotation method of fine-grained wolframite ore. In the actual beneficiation process, the separation of wolframite ore is generally completed by a combined beneficiation method, such as a combination of multiple gravity separations, or magnetic separation. - Heavy combined, floating-heavy combined and other operations, but no matter which combined process, it is necessary to conduct a beneficiation test analysis first, and determine the appropriate beneficiation process and complete set of mineral processing technology according to the actual situation of wolframite orewolframite mineral processing equipment is more reasonable.
