The flotation of lead mineral from a low grade lead–zinc sulfide ore has been investigated using a laboratory scale mechanical flotation cell. The effect of various operating parameters including type and concentration of collectors, pulp pH, grinding time, solid-in-pulp concentration on the flotation behavior of lead mineral have been studied.

As in most lead-zinc flotation operations, lead is separated first, followed by the zinc flotation stage. Due to the nature of the ore, lead minerals are frequently released from their gangue in coarse sizes, while zinc minerals need comparatively more grinding to produce the appropriate degree of liberation from accompanying gangue minerals.
