I believe this problem which there are too many slime pulp in mining has bothered a lot of people. If there are too many slime, it will be much effect the efficiency of ball mill. After years of henghong mining machine for clients to solve the separation problem of practice, the issue of slime accumulated very rich experience, the following will briefly the way how to deal with issue of ball mill in the slurry in the operation of the slime.
1, to reduce and prevent the formation of slime: can use period of grinding process, and the phase separation process. Want to correct selection of grinding and classification equipment, improve the efficiency of classifier;
2, add, remove slime harmful agents: commonly used sodium silicate, soda ash, caustic soda, etc., can reduce the slime flocculating lid. In order to reduce the harmful effects of slime large adsorption agent, consider using piecewise dosing method;
3, the grinding good ore desliming before flotation, as tailings. If useful composition content is higher in the slime, can also take off the slime flotation process alone, or water treatment.
Commonly used desliming methods and equipment mainly include: 1, the classifier desliming; 2, hydrocyclone desliming; 3, under special circumstances, can add a small amount of foaming agent before flotation, use easy floating slime flotation emerge.
