Abstract: Apparatus or recovering a mineral particle of interest from a slurry in a mineral extraction process, featuring a core or substrate; and multiple layers arranged on the core or substrate, each layer of the multiple layers configured with a respective outer surface having a plurality of molecules attached thereto, the molecules comprising a functional group selected for attracting and attaching one or more mineral particles of interest to the molecules. Each layer is made from a polymer having a thickness of less than or equal to about 125 microns. The polymer is selected from a group consisting of polydimethylsiloxane or dimethyl siloxane.

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: Apparatus for use in, or forming part of, a separation process to be implemented in separation processor technology, the apparatus comprising synthetic bubbles or beads configured with a polymer or polymer-based material functionalized to attach to a valuable material in a mixture so as to form an enriched synthetic bubbles or beads having the valuable material attached thereto, and also configured to be separated from the mixture based at least partly on a difference in a physical property between the enriched synthetic bubbles or beads having the valuable material attached thereto and the mixture.

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.

Abstract: A mineral extraction system features at least one hydrocyclone, each having input piping, underflow piping, a cyclone portion and overflow piping; a particle size measurement device arranged on some part of the at least one hydrocyclone and configured to sense particles flowing in a process medium, and providing signaling containing information about the size of the particles in the process medium; and a controller having a signal processor configured to receive the signaling, and determine control signaling to control some part of the mineral extraction system, based upon the signaling received.
