Lead - zinc ore processing technology mainly includes : crushing, grinding, beneficiation three processes. In the crushing process, three-stage closed-circuit crushing is a modern crushing method suitable for high-hardness lead-zinc ore, which can complete ore crushing and partial dissociation, thereby improving the subsequent grinding efficiency. In the grinding process, two-stage closed grinding can make lead-zinc ore grinding more fully ; in the beneficiation process, the more successful new technology in recent years is mainly the mixed flotation process.

Crushing screening-large pieces of lead-zinc ore are evenly sent to the jaw crusher or coarse crushing mobile station by the vibrating feeder through the silo for coarse crushing ; after the coarsely crushed lead-zinc ore is screened by the vibrating screen, it is sent by the belt conveyor to the single-cylinder hydraulic cone crusher for medium crushing ; the lead-zinc ore materials after crushing are sent to a multi-cylinder hydraulic cone crusher for fine crushing ;

Grinding-The 0-12 mm lead-zinc ore screened by the vibrating screen is evenly sent to the mill for grinding, and screened by the spiral classifier. Those that do not meet the requirements are sent to the mill to continue grinding.

Beneficiation-Powder ore that meets the requirements of beneficiation is sent to a magnetic separator for strong magnetic separation to remove impurities, and the obtained ore powder is sent to a dryer for drying to obtain a concentrate.
