Flotation process and equipment of lead-zinc ore In the beneficiation of lead-zinc ore, flotation is an important process. Mixing in mixing tank: After the ground pulp is classified by the classifier, it enters the mixing tank for mixing. Control the slurry concentration at 25-35%, then add flotation agent to control the slurry pH value 9-11 and stir it for 6-15 min.
