Urea as promoter in the soap flotation of phosphate ores

Phosphate ores containing siliceous gangue minerals are beneficiated by recovering phosphate mineral into froth product by using soap or soap-fuel oil emulsion as collector and sodium silicate as depressant. We show here that urea a polar, non electrolyte improves both the recovery and grade of phos...

Summary:Phosphate ores containing siliceous gangue minerals are beneficiated by recovering phosphate mineral into froth product by using soap or soap-fuel oil emulsion as collector and sodium silicate as depressant. We show here that urea a polar, non electrolyte improves both the recovery and grade of phosphate concentrate when used along with the soap-fuel oil emulsion.
