Classification and function of flotation reagents

        First, the collector

Point of action: solid-liquid interface, and selective.
Function: Improve hydrophobicity, increase floatability, promote bubble adhesion, and enhance adhesion firmness.
Second, the foaming agent
Action point: gas-liquid interface.
Function: reduce the surface tension of the interface, promote the air to diffuse in the slurry, form small bubbles, and prevent the merger of bubbles, increase the sorting interface, and improve the stability of the bubble.
Third, the adjustment agent
1. Activator
Action point: solid-liquid interface.
Role: to promote the role of collectors and mineral surfaces.
2. Inhibitor
Action point: solid-liquid interface.
Role: weaken the role between non-target minerals and collectors.
3. Medium pH adjuster
Point of action: pulp medium.
Role: adjust the electrical properties.
4. Dispersion and flocculant
Point of action: pulp.
Function: Disperse flocculated fine mud and reduce the impact.
5. Hydrocarbon oil capture process
(1) Hydrocarbon oil dispersion and adhesion;
(2) oil droplets unfolding;
(3) Forming an oil film.
Auxiliary capture of hydrocarbon oils: (1) assisted capture; (2) solvent, emulsifier
