Abstract:
     An electric level controlled floatation technology for lead zinc sulfuride ore features that in the step of floating lead, the electric level of ore sludge is regulated to 140-210 mv by adding lime into grinder while the capturer is added, and in the step of floating zinc the electric level of ore sledge is regulated to 150-170 mv by adding lime to lead tailings while adding capturer. Its odvantage is high recovery rate.
