A New Technique for the Consolidation of Mineral Slimes.
Min Cong J 1979 May; 65(5):29-31
One of the Bureau of Mines missions is the minimization of environmental degradation of mineral-processing wastes. For several years, the Bureau has conducted research directed toward the consolidation and dewatering of colloidal waste mineral slimes. By evaluating various reagents to flocculate and dewater several waste slimes, a polyethylene oxide was superior to other reagents tested when used in a specialized flocculation-dewatering technique. The flocculation-dewatering method was investigated on a bench scale and applied in continuous dewatering tests using standard mineral processing equipment. Two essential requirements of the consolidation system that were developed are proper mixing of the slime feed and flocculant, and rapid removal of water as it is released.
