Abstract: A selective recirculation circuit has a loading stage, a stripping stage and a filtering stage for use in processing a feed stream or slurry containing mineral particles. The stripping stage forms a first loop with the loading stage, and a second loop with the filtering stage. The loading stage has a loading mixer and a loading washing screen. The stripping stage has a stripping mixer and a stripping washing screen. The loading mixer receives the slurry and causes barren media in the circuit to contact with the slurry so that the mineral particles in the slurry are loaded onto the barren media. The media is directed to the stripping stage where the mineral particles are removed from the media. The barren media is recycled to the loading stage. The stripping solution recovered from the filtering stage is returned to the stripping stage and the mineral particles are discharged as concentrate.

Abstract: Apparatus features a signal processor or signal processing module configured to: receive signaling containing information about an acoustic noise profile that is directly measured and generated by a slurry hitting a probe configured in a part of a cyclone; and determine corresponding signaling containing information about the status of the part of the cyclone, based upon the signaling received. The signal processor or signal processing module is configured to provide the corresponding signaling, including where the corresponding signaling provided contains information about whether the part of the cyclone is damaged or worn. The part of the cyclone is an apex of the cyclone, and the corresponding signaling contains information about the status of the apex of the cyclone.

Abstract: A transportable modular system for enhanced minerals recovery from tailings lines and deposits, features two transportable mineral recovery modules (TMRM), each TMRM for transporting as a truck mounted module to a remote site as an independently-operable mineral recovery module, each TMRM to couple to another TMRM on-site at the remote site and used together to provide enhanced minerals recovery. One TMRM having a central engineered polymer mineral recovery module that receives tailings fluid having a mineral particle of interest, processes the tailings fluid using an engineered polymer configuration, and provides recovered mineral processing fluids having the mineral particle of interest and a tailings disposal fluid. One other TMRM is selected from a group of TMRMs that includes another central engineered polymer mineral recovery module, a tailings fluid management module, an additive/chemical treatment polymer management module, a tailings disposal module and a recovery mineral processing module.

Abstract: An engineered collection medium for use in mineral separation is described. The engineered collection medium has a solid phase body configured with a three-dimensional open-cell structure like foam or sponge to provide collection surfaces. The surfaces are functionalized with a hydrophobic chemical having molecules with a functional group for attaching mineral particles to the collection surfaces. The engineered collection medium can be a foam block, a filter or conveyor belt to be placed in a slurry to collect mineral particles in the slurry. The engineered collection medium carrying the mineral particles is provided to a release apparatus where the mineral particles can be released by using mechanical agitation, sonic agitation and so forth.
