(1) Collector function: It can selectively adsorb on the surface of the material particles to enhance its hydrophobicity, improve its floatability, and firmly adhere to bubbles and float characteristics: 1) strong collection effect, with sufficient activity; 2) high selectivity, it is better to collect only one kind of material particles; It is easy to dissolve in water, non-toxic, odorless, stable in composition and not easy to deteriorate.
(2) Foaming agent action: Foaming agent is a kind of surface active substance, mainly Acting on the water-air interface, reducing its interfacial tension, causing air to disperse in slurry, forming small bubbles, preventing bubble merger, increasing separation interface, improving the stability of bubble and particle adhesion and floating process, in order to ensure bubble on Float to form bubble end layer. Features: 1. less dosage, more bubbles can be formed, uniform distribution, suitable size, suitable toughness and viscosity; 2. good fluidity, appropriate water-solubility, non-toxic, non-corrosive, easy to use; 3. no collection effect, slurry pH changes and slurry particles of various substances have a better adaptability;
(3) Regulating agent action: mainly adjusting the interaction between other agents (mainly collectors) and the surface of material particles. It can also adjust the properties of slurry and improve the selectivity of flotation process: 1. Activator can promote the effect of collector and particles, and improve the flotability of particles; 2. Regulator can adjust the properties of slurry, so that slurry is beneficial to the flotation of some particles, but to the flotation of other particles. (3) Inhibitors weaken the interaction between non-separating substance particles and collectors, inhibit their flotability, increase the flotability difference between non-separating substance particles and the ones to be selected, and improve the selectivity of the separation process; (4) Dispersion, agglomeration and flocculation of fine mud in dispersing and coagulant adjusting materials to reduce the adverse effects of fine mud on flotation. Improve and improve the flotation effect.
