GRINDING AS A MEANS OF REDUCING FLOCCULANT REQUIREMENTS FOR DESTABILIZING SLUDGE (TAILINGS)

摘要

GRINDING AS A MEANS OF REDUCING FLOCCULANT REQUIREMENTS FOR DESTABILIZING SLUDGE (TAILINGS) Wet-grinding of the oil-removed sludge suspensions is a better means of producing new reactive surfaces on the constituent minerals in the sludge than blender-grinding. Prior treatment of the sludge by wet-grinding reduces the requirement of flocculant 573C by several orders of magnitude to achieve similar results of sludge flocculation as estimated by sedimentation using centrifugation. This grinding process will work with other applicable flocculants.
