Lead-zinc ore, being a high-hardness ore, requires significantly different crushing and beneficiation processes compared to ordinary ores. So, what is the beneficiation process for lead-zinc ore? And what equipment should be selected?

Lead-Zinc Ore Processing Process

Lead-zinc ore processing mainly includes three steps: crushing, grinding, and beneficiation.

Crushing Process

Three-stage closed-circuit crushing is currently the most suitable crushing method for high-hardness lead-zinc ore. It effectively crushes and partially liberates the ore, thereby improving the efficiency of subsequent grinding.

Large pieces of lead-zinc ore are first evenly fed into a jaw crusher or a primary crushing mobile station via a vibrating feeder for initial crushing.

The coarsely crushed lead-zinc ore is screened by a vibrating screen and then conveyed by a belt conveyor to a single-cylinder hydraulic cone crusher for secondary crushing.

The secondary-crushed lead-zinc ore material is further fed into a multi-cylinder hydraulic cone crusher for fine crushing.

Grinding Process

Two-stage closed-circuit grinding allows for more thorough grinding of lead-zinc ore.

The 0-12 mm lead-zinc ore after screening is evenly fed into the grinding mill for grinding, and then screened by a spiral classifier. Material that does not meet the requirements is returned to the grinding mill for further grinding.

Mineral Processing Process

In recent years, mixed flotation has become one of the more successful new processes in lead-zinc ore beneficiation.

The ore powder meeting the beneficiation requirements is first fed into a magnetic separator for strong magnetic separation to remove impurities.

Then, the obtained ore powder is sent to a dryer for drying to obtain concentrate.
