Common Types of Flotation Promoters/Collectors The common promoters for metallic flotation are xanthates, aerofloats, minerec, and thiocarbanilide. Soaps, fatty acids, and amines are commonly used for non-metallic minerals such as fluorspar, phosphate, quartz, felpsar, etc.

Mineral processing - Wikipedia

These considerations include the pH, Eh and the presence of flotation reagents. The pH is important as it changes the charge of the particles surface and the pH affects the chemisorption of collectors on the surface of the particles. The addition of flotation reagents also affects the operation of these processes.
