Abstract: The disclosure relates generally to the use of low molecular weight polymers to aggregate mineral components in aqueous mineral slurries to release and separate individual components of the slurry, which may then be recovered from the slurry.

Abstract: The disclosure relates generally to the use of zeolite to assist in dispersion of components in aqueous mineral slurries to release and separate individual components of the slurry, which may then be recovered from the slurry and, in particular, to the use of zeolite in the recovery of bitumen from an oil sands slurry, water recovery from the slurry, and the subsequent consolidation of residual mineral solids.

Abstract: A method of coagulating particulates, as in papermaking or water clarification applications, for example, is provided wherein a zeolite crystalloid coagulant is added to water containing the solid matter, a source of multivalent cations, and a cationic acrylamide polymer. The zeolite crystalloid coagulant is preferably prepared by admixing aqueous sodium silicate and sodium aluminate solutions to form a reaction mixture and allowing a reaction to proceed for a sufficient time to form a zeolite crystalloid coagulant particles having particle sizes of at least about 4 nm before terminating the reaction.

Abstract: A centrifuge such as a continuous solid bowl centrifuge, for example, includes a rotatable bowl for receiving a slurry, and defines a zone in which the slurry is accelerated. The centrifuge includes a device such as a slurry feed tube for delivering slurry to the acceleration zone and a device for delivering a plurality of individual streams of flocculant solution coterminating with the slurry delivery device in order to uniformly distribute flocculant solution to the slurry.

Abstract: A collapsible intermediate bulk container for liquid or freely flowable solid materials includes either a fabric outer/film liner bag or a bag of fabric reinforced elastomer. The bag is supported by a collapsible rigid frame which gradually collapses as the bag is emptied. The collapsible rigid frame includes a pallet-base portion that has an upper surface that is sloped to a center drainage point to facilitate complete emptying. The pallet-base portion contains a valve arrangement fixed to either the fabric outer bag (in the film-lined configuration) or to the reinforced fabric bag, at the center drainage point. The collapsed frame provides a compact return package. Either bag configuration may be reused or replaced in whole or in part.

Abstract: A reactor for the production or formulation of flowable viscous products is equipped with an internal piston which assists in the removal of product from the reactor interior.
