First, the mineral was pretreated through grinding, sorting and discarding slimes. The effect on flotation of pH, collector concentration, particle size and flotation time was then analyzed. The results achieved show that a neutral or slightly alkaline pH and short flotation times promote the concentration of sedimentary phosphorite.

Experimental results carried out by Wilson and Ellis (1984) showed that the flotation techniques applied on a calcareous ore may be effective only if the phosphate can be highly liberated from the gangue materials in a relatively coarse size. In the case of the unaltered ores, complete liberation is achieved only with extremely fine grinding.
