· Flotation reagents may be roughly classified, according to their function, into the following groups: Frothers, Promoters, Depressants, Activators, Sulphidizers, Regulators. The order of these groups is no indication of their relative importance; and it is common for some reagents to fall into more than one group.

· Often up to 70-80% of the lead can be recovered at this point in a high grade product which filters rapidly and is generally very low in zinc content. Zinc depressant reagents are at their highest concentration in the grinding circuit; hence, selectivity of separation by flotation is often at its best right at this point.

· Flotation. According to the difference in physicochemical properties of mineral particle surfaces, flotation is the method that selectively enriches the target minerals in the pulp at the gas-liquid interface and separates them from the pulp, thus realizing the mineral separation. It is also known as floating separation.
