Water chemistry is one of the most important parameters affecting flotation performance. Various types of ions can dissolve and accumulate in process water depending on ore mineralogy, reagent scheme, grinding medium and chemistry of mine site water. Sulfur-based ions (sulfate, thiosulfate, polythionate) are generally observed in flotation of sulfide ores. High concentrations of these ions may.

Apr 23, 2020 Froth flotation is the most widely used phosphate ore separation process. Because of the nature of the phosphate ore, such as mineral types and content, disseminated particle size, its separation difficulty and flotation types varies. Phosphate ore is divided into siliceous phosphorite, calcareous phosphorite, and siliceous phosphorite according to the chemical composition of the.
