Electrokinetic Dewatering of Eneabba West Mine Tailings:

It is concluded that the Eneabba West Mine tailings are feasible for electrokinetic dewatering This is demonstrated by the electroosmotic permeability in the range of 32 to 47 x 10 –9 m 2 /sV; the electrokinetic consolidation ratio in the range of 01 to 20 m/V; and the coefficient of electrokinetic water transport in the range of 51 to 6electrokinetic dewatering of sand washery tailings and reported favorable dewatering with a low energy consumption of 1 kWh per dry ton Bayat et al [9] studied the electrokinetic dewatering of fine glass sand tailings (d 80 finer than 2 μm) in the laboratory, where the solid content was increased fromElectrokinetic Dewatering of Mine Tailings Using DSA

Electrokinetic Dewatering of Mine Tailings

Dewatering of Mine Tailings The process of diamond extraction is reliant on large quantities of water to concentrate the mineral; this produces large quantities of waste The process results in two broad types of discard material, which are differentiated according to their dominant grain size: grits (>75 µm) and slimes (<75 µm)In this study, the dewatering of glass sand plant tailings from Mersin, Turkey was investigated using an electrokinetic technique The particle size (d 8 0) of the solid waste material tested was less than 0020 mm and consisted mainly of silica, orthoclase, alumina, potassium and iron oxides In current plant practice, Larox highpressure filters are used to produce a filter cake containingElectrokinetic dewatering of Turkish glass sand plant tailings
