Froth flotation:According to the different separation methods, it can be divided into the following categories:
Mineral flotation Coarse flotation Particle flotation Ion flotation and molecular flotation The precipitate flotation Adsorbing colloid flotation
The main process of froth flotation is the bubble rise with mineral, then enrich foam layer formed on the surface of the slurry. This process is simple, but the details is complex, its adaptability and effectiveness make bubble flotation wipe become sorting complex, a method most widely used in low-grade ore dressing.
1. Froth impurity（Reverse flotation）.
2. Froth extraction (positive flotation).
The formation of foam bubbles geometry consists of two parts, One is foam, two or more bubbles, second is the membrane between foam and the foam is composed of a small amount of liquid foam skeleton.
Minerals whether floating or not, depending on the activity of the mineral surface.Most of their nature mineral floatability are poor. Relying solely on the difference in wettability can not be successfully separated among mineral minerals. The role of flotation reagent flotation process is to change the nature of the phase interface. The main drug used in the collector agent and adjust agent like.
1. Hydrometallurgy ore flotation.
2. Bioengineering of cell separation, protein separation.
3. Industrial wastewater treatment.
