Conditions necessary for froth flotation

Conditions necessary for froth flotation

May 26, 2020 Factor 3: Flotation Time. Flotation time is also an important factor affecting the phosphate froth flotation index. Other conditions being the same, the flotation effect is determined by the flotation time. The relationship between recovery rate and grade of phosphate concentrate P 2 O 5 and flotation time is shown in Figure 3
