Process flow chart of lead-zinc mine

The process flow chart of lead-zinc mine generally includes four stages: crushing, grinding, flotation, and dewatering. The specific process flow chart can be designed according to the ore grade and the customer's requirements.

1. Crushing stage: The large pieces of lead-zinc ore are evenly sent to the jaw crusher or the mobile jaw crusher for primary crushing by the vibrating feeder. The coarse particles are sent to the cone crusher for secondary crushing, and the crushed ore is sent to the vibrating screen for screening.

2. Grinding stage: After the lead-zinc ore is crushed and screened, it is sent to the ball mill for grinding. The ball mill can be used for both dry and wet grinding, and the output can be adjusted according to the specific situation.

3. Flotation stage: After grinding, the lead-zinc ore slurry is sent to the flotation machine. The flotation machine adds various reagents according to the properties of the ore to achieve the separation of the minerals. The froth product contains lead and zinc minerals, while the tailings contain gangue minerals.

4. Dewatering stage: After flotation, the lead-zinc concentrate is sent to the thickener for concentration and then filtered. The filtered concentrate is dried and sent to the smelter for smelting. The tailings are sent to the tailings dam for storage.

In addition, some lead-zinc mines also add gravity separation, magnetic separation, and other mineral processing methods according to the specific characteristics of the ore to improve the recovery rate and reduce the production cost.

Overall, the lead-zinc mine process flow chart is relatively simple, but the selection of equipment and reagents requires professional technical knowledge and experience to ensure the efficiency and quality of the beneficiation process.
