METHOD FOR TREATING AND CONDITIONING TAILINGS
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. Superabsor...

| 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.
L'invention concerne un procédé de stabilisation physique pour boues ou bouillies combinant des particules grossières à une bouillie de particules fines pour générer une bouillie composée ayant un rapport sensiblement prédéterminé de particules grossières et de particules fines. La bouillie composée peut alors être diluée, floculée et/ou décantée. Un polymère superabsorbant (SAP) est mélangé à la bouillie composée décantée selon une quantité permettant de produire une composition transportable, sans séparation et stable au cisaillement, de résistance suffisante pour permettre le pompage, le transport et le positionnement sur un site minier ou un site d'élimination des résidus. |
