Abstract
A process of phosphate flotation comprising: pulping phosphate ore with water to about 55% to 75% solids to produce an ore slurry; conditioning the ore slurry with a new reagent scheme to produce a conditioned slurry; subjecting the conditioned slurry to flotation to produce an underflow and an overflow; and collecting the overflow as phosphate concentrate. The new reagent scheme may comprise a combination of fatty acid, fuel oil, and fatty acid soap, and may not comprise a pH modifier. The process may also work effectively at a lower percent solids than conventional reagent schemes.
