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
2018-2-9 · Frothers are very important reagents playing a multiple role in flotation of particulate matter. The frothers facilitate formation of either foam or froth and favourably modify the structure of films between bubbles as well as solid particles and bubbles [1–7]. Frothers also interact with collectors

In mineral processing, frothers are used to produce small persistent air bubbles. The role of the frother is to produce a stable and mobile froth so that the targeted hydrophobic particles can be picked up and floated to the top of the float cell where they are concentrated for further processing. Frothers
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.
