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 dewatered. Superabsorbent polymer (SAP) is mixed in with the dewatered composite slurry in an amount effective to produce a somewhat friable, semi-solid conveyable composition of sufficient strength to enable transport, stacking and support of restored overburden at a mining 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稍微易碎的半固体可输送组合物，以使得能够在采矿部位运输，堆叠和支撑恢复的覆盖层。
