Metal lead has the advantages of low melting point, high corrosion resistance, X-ray and gamma-ray, good plasticity, etc., and is often processed into plates and pipes, and is widely used in the industrial fields of chemical industry, cable, battery and radioactive protection. Zinc is an important material in the battery manufacturing process.

[0003] A Chinese patent application file with the publication number CN117646113A discloses a combined device and method for flotation-metallurgy of lead and zinc in refractory complex ore, which comprises a flotation system and an oxygen pressure acid leaching system. The flotation system comprises a flotation device connected in sequence. The oxygen pressure acid leaching system comprises a first-stage oxygen pressure acid leaching system and a second-stage oxygen pressure acid leaching system, a desulfurization reactor and a lead selection reactor. The desulfurization reactor comprises a rotatable tank cover and a solid-liquid separator. The lead selection reactor comprises a temperature control system and a solid-liquid separation pipe. The steps of using the device are as follows: the raw ore is mixed and floated to separate lead and zinc in the flotation system, and the mixed lead-zinc concentrate is sent to the oxygen pressure acid leaching system to extract lead and zinc respectively. The present application has the characteristics of good metal recovery effect, clear and smooth process flow, convenient operation and environmental friendliness.

[0004] A Chinese patent application file with the publication number CN118384571A discloses an environment-friendly plate and frame filter press. The structure comprises: two or more filter plates are installed between the pressing plate and the positioning frame, and the pressing plate is driven by the driving frame to press the filter plates. Connecting rods are installed between the filter plates to pull the adjacent filter plates to move. The filter plate comprises a plate frame, and rotatable carriages are arranged on both sides of the plate frame. A through-flow pipe is arranged in the middle of the plate frame. The improved device pulls the filter plates through the partition device, and the connecting rods are arranged between the filter plates to link them. The multiple filter plates can move synchronously. The carriages installed on the side edges of the plate frame are in a rotating structure.

Resetting torsional springs are arranged between the carriages to control the angle of oscillation of the plate frame, and the plate frame can be reset after stopping to avoid the interlocking of the plate frames after pulling.
