Lead and zinc used collector:
1.Xanthate such agents include the xanthate, xanthate ester, etc.
2.Sulfur nitrogen,such as diethyldithiocarbamate, its collecting capacity than xanthate.It galena,chalcopyrite collecting capacity, collecting capacity school weak pyrite selective flotation faster, uses less than xanthate. Sulfide ore coarse raw body stronger collectors than it used to be able to get better than xanthate separation efficiency, copper and lead sulfide ore sorting.
3.Black medicine
The black drug sulfide ore effective collector, the collector than xanthate weak dialkyl dithiophosphate of the same metal ion solubility product than that of the corresponding ion Xanthates large.Black medicine has foamability.
The flotation beneficiation is the most commonly used method of mineral concentration process, economic, convenient, efficient, high-grade ore dressing.Usually lead-zinc beneficiation production line consists of jaw crusher, ball mill, spiral classifier, the mixing tube, flotation machine, dryer and conveyor, spiral washing machines and other equipment. Flotation machine is the important machine in flotation device,the pulp fully inflated stirring, the useful minerals enriched completed flotation. Important step in the process is the selection and operation of the flotation reagent, so as to achieve the purpose of good beneficiation. Compared with other beneficiation methods,the flotation beneficiation economy is reasonable, the effect is very good.
