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.

flotation. Once conditioned, the ore is then slurried with water and various types of chemical reagents that promote flotation (collectors, frothers, activators, and depressants). Flotation typically occurs in a series of steps and multiple floats may be required to remove several different mineral values from a polymetallic ore. The residues (tailings) from one float are often used as the
