Purification equipment for lead-zinc ore
June.19,2025
Zinc suppression and lead recovery strategies are commonly used for lead-zinc separation, such as zinc sulfate + sodium sulfite combined inhibitor.
Copper-lead separation requires drug removal pretreatment, such as activated carbon adsorption of residual reagents, or potassium dichromate to suppress lead minerals.
Concentrate re-grinding, only fine grinding of mixed concentrate, saving costs while improving monomer dissociation degree, such as a mine in Yunnan after transformation, the daily processing capacity increased by 36%, and the annual profit increased by 7.8 million yuan.
Gravity selection auxiliary: Use a shaking table to purify the impure crude lead concentrate.
