Publication number: 20120313038Abstract: 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.Type: ApplicationFiled: February 3, 2011Publication date: December 13, 2012Applicant: FLSMIDTH A/SInventors: Timothy J.
