Abstract: A sludge or slurry physical stabilizing method combines coarse particles with a slurry of fine particles to generate a composite slurry having a substantially predetermined ratio of coarse particles to fine particles. The composite slurry can then be diluted, flocculated and/or dewatered. Superabsorbent polymer (SAP) is mixed in with the dewatered composite slurry in an amount effective to produce a shear stable, non-segregating conveyable composition of sufficient strength to enable pumping, transport and placement at a mining site or tailings disposal site.

Abstract translation: 污泥或浆料物理稳定方法将粗颗粒与细颗粒的浆料结合以产生具有基本上预定比例的粗颗粒与细颗粒的复合浆料。 然后可以将复合浆料稀释，絮凝和/或脱水。 将超吸收性聚合物（SAP）与脱水的复合浆料混合，其量有效地产生足够强度的剪切稳定的，非分离的可输送组合物，以使得能够在采矿地点或尾矿处理场地进行泵送，运输和放置。
