Zinc Ore Production Plant

For a zinc extraction plant in Tibet, there are much slime in the raw ore. According to the zinc ore characteristics, Xinhai adopted pre-desliming, zinc sulfide flotation and zinc oxide flotation process. Finally, the production indexes were stable and the recovery rate of zinc reached 69.56%.
