Ore-type-based beneficiation for sulfide, oxide, and polymetallic lead-zinc ores.
Sulfide lead-zinc ore is mainly processed by flotation separation.
Oxide lead-zinc ore can use flotation, gravity-flotation, roasting-flotation, or sulfuric-acid-treatment flotation.
Polymetallic lead-zinc ore can use magnetic-flotation, gravity-flotation, or gravity-magnetic-flotation.
Complete process includes grinding, classification, lead flotation, conditioning, pH control, roughing, cleaning, desliming, and EPC service.

The process improves lead and zinc recovery through grinding, classification, lead flotation, zinc flotation, desliming, reagent conditioning, roughing, and cleaning flotation stages.
Optimized grinding, slurry concentration control, flotation time, and desliming help reduce unnecessary circulation and improve beneficiation efficiency.
The production line can be configured with automatic grinding, classification, slurry mixing, pH control, reagent dosing, flotation, desliming, and concentrate collection systems.
The process can be customized according to ore type, mud content, mineral composition, flotation behavior, particle size, and final concentrate requirements.
Lead-zinc ore is ground to prepare suitable particle size for mineral separation.
Ground slurry is classified before entering the next beneficiation stage. Row 3
The classified material is washed to remove mud and improve separation conditions.
Magnetic separation removes magnetic impurities before flotation recovery.
The slurry enters rougher flotation for the first-stage recovery of valuable minerals.
Part of the stream is treated by gravity separation to improve mineral recovery.
Multiple roughing and scavenging stages recover more valuable lead-zinc minerals. Row 8
Multiple cleaning and scavenging stages improve concentrate grade and product quality.
Remaining material enters tailing flotation for further recovery before waste discharge.
The process produces concentrate as the final product and tailing as waste.

Suitable flotation and combined beneficiation processes help improve lead and zinc mineral recovery from different ore types.
Controlling slurry concentration within a suitable range supports better reagent mixing and flotation performance.
Proper pH control helps create suitable flotation conditions for lead-zinc mineral separation.
Desliming removes fine slime below -0.074 mm to improve flotation efficiency and concentrate quality.
