Lead-zinc ore processing
Lead-zinc ore introduction:
The processing technology of lead-zinc ore mainly includes three processes: crushing, grinding and beneficiation.In the process of crushing, the three-stage closed-circuit crushing is modern and suitable for the crushing of high-hardness lead-zinc ore, which can complete the work of ore crushing and partial dissociation, thereby improving the subsequent grinding efficiency;During the grinding process, the second-stage and one-close grinding is a grinding process, which can make the lead-zinc mine more fully ground;Among the beneficiation processes, the more successful new processes that have emerged in recent years are representative of the mixed flotation process.
Lead-zinc ore processing:
The first stage: crushing and screening – three sections of closed circuit broken
The bulk manganese ore is uniformly sent to the jaw crusher or the mobile jaw crusher by the vibrating feeder for coarse crushing;The coarsely crushed manganese ore is sieved by a vibrating screen sieve and then sent to a single-cylinder hydraulic cone crusher by a belt conveyor for medium crushing;The crushed manganese ore material is sent to a multi-cylinder hydraulic cone crusher for fine crushing;
Second stage: milling
The 0-12 mm lead-zinc ore sieved through the vibrating screen is evenly sent to the scoring mill for grinding, and is sieved by a spiral classifier. If it does not meet the requirements, it is sent to the ball mill to continue grinding;
The third stage: dressing
The lead-zinc powder meeting the beneficiation requirements is sent to the magnetic separator for strong magnetic separation to remove the impurities, and the obtained lead powder and zinc powder are sent to the dryer for drying.
