Lead-zinc ore beneficiation production process

Lead-zinc ore is a common non-ferrous metal mineral. It is widely used in metallurgy, chemical industry, light industry, and other fields due to its excellent performance. The lead-zinc ore beneficiation production process includes crushing, grinding, and beneficiation.

Firstly, the lead-zinc ore is crushed into small pieces by jaw crusher or cone crusher. Then, it is sent to the ball mill for grinding. After the ball mill grinding process, the lead-zinc ore pulp is sent to the spiral classifier for classification. The qualified lead-zinc ore particles are sent to the flotation machine for flotation.

In the flotation process, various agents such as collectors, foaming agents, and regulators are added to the flotation machine. Under the action of these agents, the lead minerals and zinc minerals in the pulp are separated from each other. The separated lead minerals are sent to the lead concentrate storage tank, and the separated zinc minerals are sent to the zinc concentrate storage tank.

After the flotation process, the lead concentrate and zinc concentrate need to be dewatered. The lead concentrate and zinc concentrate are sent to the filter press for dewatering. After the dewatering process, the lead concentrate and zinc concentrate become the final products. The tailings are sent to the tailings pond for storage.

In the lead-zinc ore beneficiation production process, various types of equipment are used, including jaw crushers, cone crushers, ball mills, spiral classifiers, flotation machines, filter presses, and tailings ponds. The choice of equipment depends on the characteristics of the ore and the production capacity.

In addition to the above beneficiation process, some lead-zinc mines also use gravity separation and magnetic separation methods to separate the lead minerals and zinc minerals in the ore. The gravity separation method is mainly used for the separation of coarse-grained lead and zinc minerals, while the magnetic separation method is mainly used for the separation of fine-grained lead and zinc minerals.

In conclusion, the lead-zinc ore beneficiation production process is a complex process that involves crushing, grinding, beneficiation, dewatering, and tailings storage. The selection of appropriate equipment is essential to ensure the efficiency and quality of the beneficiation process.
