Abstract: Apparatus uses engineered collection media to recover mineral particles in a mineral extraction process, e.g., for processing a tailings stream at the end of a flotation separation process. The engineered collection media are added to slurry/tailings containing the mineral particles. The engineered collection media have collection surfaces coated with a chemical selected for attracting the mineral particles to the collection surfaces so the engineered collection media becomes mineral laden media in the slurry/tailings in a loading stage. The apparatus include three stages: removing unwanted material from mineral laden media; using a stripping agent to strip the mineral particles from the mineral laden media; and separating the engineered collection media from the mineral particles and the stripping agent. The stripping agent is reused for stripping, and the engineered collection media are returned to the loading stage. The engineered collection media can have a smooth or foam-like surface.

Abstract: A substrate for use in an aqueous slurry has a polymeric coating to provide a compliant and sticky surface. The polymer coating has a chemical to render the surface hydrophobic so as to attract hydrophobic or hydrophobized mineral particles in the slurry. The surface has a surface roughness structure in the nano-scale to micro-scale range. The substrate can take the form of a conveyor belt, a bead, a mesh, an impeller, a filter or a flat surface. The substrate can also be an open-cell foam. The polymeric coating can be modified with tackifiers; plasticizers; crosslinking agents; chain transfer agents; chain extenders; adhesion promoters; aryl or alky copolymers; fluorinated copolymers and/or additives; hydrophobicizing agents such as hexamethyldisilazane; inorganic particles such as silica, hydrophobic silica, and/or fumed hydrophobic silica; MQ resin; and/or other additives to control and modify the properties of the polymer.

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: A synthetic bead for use in mineral separation is described. The synthetic bead has a surface made of a synthetic material such as polymer and the synthetic material is functionalized with molecules having a functional group for attracting mineral particles to the surface in a separation process. The synthetic beads can be placed in flotation cell containing a mixture of water, valuable material and unwanted material or in a pipeline where the mixture is transported from one location to another. The enriched synthetic beads carrying the mineral particles are separated from the unwanted materials in the mixture. The mineral particles are then released from the synthetic beads by means of low pH treatment, ultrasonic agitation, thermal or electromagnetic treatment.

Abstract: Method of separating individual cathode active materials from a mixture of cathode active materials by froth flotation has been developed. They are based on using appropriate chemical reagents that selectively hydrophobize individual cathode active materials to be recovered, so that they can be collected by air bubbles used in flotation and separated from other mixtures. The chemical reagents are amphiphilic molecules with specialized head groups have a strong affinity to metal elements on surfaces of cathode materials. This method enables a separation of individual cathode active material from a mixture of cathode active materials.

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.
