How to Process Low-Grade Lead Zinc Ore by Flotation
A thorough washing and some disintegration is given the ore by the trommel screen. The minus 2″ material passes to a cone or Forced Feed Jaw Crusher and is reduced to approximately minus ½". A Cross-Flow Classifier is used to dewater this minus ½"ore and also removes fine colloids. Classifier overflow is discarded.
Pb-Zn Mineral Processing
Lead-zinc (Pb-Zn) ores are often symbiotic together, and the flotation method is generally used for beneficiation. After the Pb-Zn ore is crushed to a certain particle size, the heavy medium is used to remove the large and low-grade waste rock, and then the enriched ore is processed by the flotation method.
