Flotation of Barium Sulfate Contaminants Soils

Abstract

Application of flotation for the removal of hydrophilic barium sulfate BaSO4 compounds from soil was studied. Micro-flotation tests were conducted on artificially contaminated soil, using a mechanically agitated machine. Flotation parameters tested include collector type and dosage, conditioning time, flotation time and pulp pH. It was found that, with single stage flotation, 85% removal of the contaminant was achieved from soil particles in the range of 80-100µm Flotation was found to have considerable potential for cleaning up contaminated; by combining attrition up to 95% of contaminant barium sulfate was achieved
