Oct 21, 2020 · What is a Flotation Collector. For industrial sulfide mineral flotation, the xanthates and dithiophosphates are the major classes of Flotation Collectors compounds used, where M+ is either Na+ or K+, and R is a relatively short hydrocarbon chain typically containing two to five carbon atoms. The solubility, pH application range, physical state

Nowadays, reverse flotation is the most commonly used route in iron ore flotation. This review is focused on the reverse flotation of iron ores, consisting of reverse cationic flotation and reverse anionic flotation. It covers different types of collecting agents used in reverse iron ore flotation, the surface characteristics of minerals commonly present in iron ores (e.g., iron oxides, quartz, alumina-bearing minerals, …
