Lead-zinc ore beneficiation method introduction:
The process flow of lead-zinc ore is selected, according to different types of ore, then choose a different beneficiation method, it also requires different lead and zinc ore processing equipment. Sulfide ore is usually floated. Oxidized ore is treated by flotation or re-election and flotation, or flotation, or flotation, or re-flotation with sulfuric acid. For multi-metal lead-zinc ore, it is generally used magnetic-floating, heavy-floating, heavy-magneto-floating concentrating methods. Lead-zinc ore processing equipment flotation process.
Lead-zinc ore processing equipment specific flotation process is as follows (for reference only)
A. Grinding argillaceous zinc oxide ore, so that the particle size of -0.1mm accounts for 50% to 80%;
B. Flotation of lead oxide by grading and overflowing of the finely divided slurry;
C. Will be lead floatation tailings into the mixing tank, control slurry concentration of 25 ~ 35%, adding flotation agent, control slurry pH 9-11, stirring 6-15min;
1. The beneficiation process is novel and the operating cost is lower
The lead-zinc mixed concentrate regrinding process eliminates the necessity of grinding all the raw ores and saves the grinding cost. At the same time, the concentrate can be reground to further dissociate the lead and zinc concentrates, and it also has good dedoping effect. It is lead-zinc. Separation with difficult substances creates favorable conditions.
2. Strengthen the flotation process, improve the concentrate grade
Strict implementation of the pharmacy system in the rough election segment to control the amount of pharmaceuticals, so that "early income can be received early," reduce multiple cycles and inaction losses; make full use of the secondary enrichment of the foam, and through the appropriate without water, The concentrate foam is rinsed to reduce the impurities in the foam to achieve the goal of enhanced flotation.
