Flotation Collector - cnfreereagent

Flotation collector is a kind of organic substance that can selectively act on the surface of minerals to make the ore particles hydrophobic, so that the ore can be catched by the foam and float to the surface of ore pulp, thus being collected. Flotation collectors have many kinds, including xanthate, dithiophosphate and

The performance of collectors can be enhanced by the use of modifiers. Modifiers may either increase the adsorption of collector onto a given mineral (promoters), or prevent collector from adsorbing onto a mineral (depressants). Promoters are a wide variety of chemicals which in one or more ways enhance the effectiveness of collectors.
