Recovery of apatite from flotation tailings
Recovering phosphorus from these tailings could provide additional and substantial amounts of phosphate. The separation of the desired mineral (apatite) from impurities (gangue minerals) and nonphosphate materials in phosphate rock requires grinding and beneficiation units [8] for some operations such as froth flotation [9].

Fundamentals of oleic acid adsorption on phosphate flotation feed
Fuel oil reduces the residual oleic acid in solution after adsorption, which explains the beneficial role of extender in phosphate flotation. The dissolved species in solution arising from the flotation feed or plant processing water are shown to clearly play a major role in determining the adsorption of oleic acid on the substrates.
