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:
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.
Abstract:
Apparatus is provided featuring a first and second cells. The first cell receives an ore slurry having mineral particles of interest, receives unexpanded polymer microspheres comprising a surface having mineral collector chemistry attached thereto with molecules for attaching the mineral particles of interest, causes the unexpanded polymer microspheres to expand substantially in volume into expanded polymer microspheres having a substantially increased sphere surface area, and provides an expanded polymer microsphere foam layer comprising the expanded polymer microspheres with attached mineral particles of interest. The second cell receives the expanded polymer microsphere foam layer, and causes the expanded polymer microspheres to collapse substantially in volume into collapsed polymer microspheres having a substantially reduced sphere surface area that results in a mechanical shearing off of the attached mineral particles of interest. The second cell may also provide a mineral concentrate output having the mineral particles of interest.

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:
Apparatus, such as a flotation separation device, features a flotation cell or column configured to receive a mixture of water, valuable material and unwanted material; receive polymer-based materials, including polymer bubbles or beads, configured to attach to the valuable material in the mixture; and provide enriched polymer-based materials, including enriched polymer bubbles or beads, having the valuable material attached thereon.
Abstract:
An apparatus and method for collecting mineral particles in the tailings is disclosed. The apparatus may take the form of a filter, a conveyor belt, a collection plate or an impeller configured to contact with tailings of a flotation process, before and/or after the tailings are discharged into a pond. The filter, conveyor belt, collection plate or impeller has a collection area or surface made of, or coated with, a synthetic material having a functional group, e.g., having an ionizing bond to attract the mineral particles of interest. Alternatively, the synthetic material has hydrophobic molecules to render the collection area hydrophobic. When the mineral particles of interest in the tailings are combined with collector molecules, the mineral particles of interest may also become hydrophobic. The hydrophobic mineral particles of interest are attracted to the hydrophobic collection area or surface. The filter, conveyor belt, collection plate and impeller may have a plurality of passage ways or synthetic beads in order to increase the contacting surfaces.
Abstract:
Apparatus is provided featuring a signal processor or processing module configured to: receive signaling containing information about at least two sensing modalities sensed by a single probe arranged in relation to a multiphase flow or process volume; and determine using a multiple modality tomographic analysis technique information about different fluid layers in the multiphase flow or process volume, based at least partly on the signaling received. The signal processor or processing module may be configured to provide corresponding signaling containing corresponding information about different fluid layers in the multiphase flow or process volume.
