1) Collector . It interacts with the surface of the mineral, and it adheres to the surface of the mineral to enhance the hydrophobicity of the mineral surface, which is beneficial to the collection of the ore particles on the bubbles. 2) Foaming agent. Foam is the medium for the floating of the ore during flotation. 3) Inhibitors. It is an agent that reduces the floatability of minerals. The surface of the ore particles can be formed into a hydrophilic film to form a colloidal adsorption film, thereby hindering the interaction of the collector with the mineral surface. At the same time, the inhibitor can also dissolve the adsorbed collector from the mineral surface or dissolve the active film which helps the collector to act. 4) Activator. It is to eliminate the inhibition, promote the floatability, and make the mineral surface cause the agent which is easy to interact with the collector. In the current production practice, some minerals can not directly adsorb the collector, often adding an activator to change the surface properties of the mineral, which is beneficial to the adsorption of the collector. 5) Medium conditioner. Its main function is to adjust the pH value of the pulp (pH value, representing pH), adjust the role of other agents, eliminate the harmful effects of ions on flotation, and adjust the dispersion and agglomeration of the slime.

According to the same way, different types of flotation drugs are divided into several categories?
In the past 100 years, flotation has made great achievements in the field of mineral processing , mainly relying on the special role of flotation reagents. Flotation agents can basically be divided into five categories:
