Lead-zinc ore characteristics

Lead-zinc ore, is rich in metal elements lead and zinc minerals, lead and zinc widely used, with the electrical industry, machinery industry, military industry, metallurgical industry, chemical industry, light industry and medicine and other fields. In addition, lead metals in the nuclear industry, oil industry and other departments have more uses.

Lead-zinc ore processing technology

The first stage: Screening & Crushing

Large pieces of lead-zinc ore from the silo by the vibrating feeder evenly into the jaw crusher, crushed lead-zinc ore after the vibrating screen screening, the belt conveyor carry the materials to the single-cylinder hydraulic cone crusher for medium crushing. After the medium crushing iron ore material into the multi-cylinder hydraulic cone crusher for fine crushing.

The second stage: Milling

Vibrating screen screening 0-12 mm lead-zinc ore powder, evenly sent to the ball mill for milling, and then by the spiral classifier screening, do not meet the requirements of particle size is back to the ball mill, continue to mill.

The third stage：Ore-dressing

In the ore-dressing process, due to the different types and properties of lead-zinc ore, the ore-dressing method is also different, but commonly used gravity separation, flotation separation, amalgamation, cyanide and today's resin in pulp process method, carbon adsorption method, heap leaching new technology and so on. For some types of ore, often use the combined process.

The fourth stage：Drying

Lead-zinc ore powder into the dryer drying can get lead-zinc ore concentrate powder.
