Abstract

A process of separating a surfactant in a liquid containing the surfactant and a solvent, includes: adding a salt to the liquid solution for providing a denser liquid and forcing soluble surfactant out of solution; and increasing a mechanical g-force applied to the denser liquid to separate the surfactant in the liquid solution. The process also includes providing the mechanical g-force via centrifugation, e.g., including by a centrifuge. The mechanical g-force may be about 690g applied to the denser liquid, e.g. for 30 to 60 seconds. The salt may be sodium chloride. The process may also include elevating the temperature of the denser liquid before the increasing the mechanical g-force.

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

Apparatus uses hydrophobic synthetic beads to recover mineral particles in a slurry. The synthetic beads and the slurry are mixed into a mixture for processing. The apparatus has an interaction vessel installed in a section of pipeline. The interaction vessel is made from a pipeline folded or coiled into a compact struction having a continuous flow path. The interaction vessel has an input to receive the mixture of slurry and synthetic beads. The folded or coiled structure is used to increase the residence time of the mixture in the flow path, allowing more time for the mineral particles in the slurry to attach to the surface of the synthetic bead, while maintaining a small footprint. The interaction vessel may be formed from a number of loops of pipe section. The interaction vessel may be formed from one or more folded structures.

Abstract

Apparatus uses engineered collection media to recover mineral particles in a slurry. The apparatus has a tumbler cell and a rotation device to rotate the tumbler cell. The tumbler cell has a container to hold a mixture of the engineered media and the slurry containing the mineral particles. The container is turned such that at least part of the mixture in the upper part of the container is caused to interact with at least part of the mixture in the lower part of the container. As such, the contact between the engineered media and the mineral particles is enhanced. The surfaces of the engineered media are functionalized with a chemical having molecules to attract the mineral particles to the surfaces so as to form mineral laden media. After the mineral laden media are discharged from the tumbler cell, the mineral particles can be separated from the engineered media by stripping.

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 modified 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, 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

A flotation tank has an input to receive a slurry from a pipeline section. The slurry contains finer mineral particles and coarser mineral particles. The pipeline section has one or more loops or coiled sections arranged to perform partial centrifugal separation on the finer and coarser mineral particles. As the mineral particles are moved tangentially into the lower part of the flotation tank, the coarser mineral particles tend to be near the tank wall while the finer mineral particles tend to move into the central part of the tank. Air bubbles or lightweight synthetic bubbles are used to collect and lift the finer mineral particles to the upper part of the tank. The coarser mineral particles are recovered by using collection surfaces coated with a hydrophobic material.

Abstract

A reactor system has a number of stations arranged to recover mineral particles in a slurry. The system includes a hopper to receive the slurry and barren media having hydrophobic coating to attract the mineral particles. The hopper provides a mixture of barren media and slurry to a tumbler arranged to stir the mixture in order to increase the contact between the slurry and the barren media so as to allow the mineral particles to attach to the barren media to form mineral laden media. The mineral laden media are conveyed to a rinsing station where water jets are used to wash the gangue materials off the mineral laden media. The rinsed mineral laden media are mixed with a surfactant so that the mineral particles are released from the mineral laden media. High-pressure water and air jets are then used to remove remaining surfactant from the released media.

Abstract

A flotation tank has an input to receive a slurry from a pipeline section. The slurry contains finer mineral particles and coarser mineral particles. The pipeline section has one or more loops or coiled sections arranged to perform partial centrifugal separation on the finer and coarser mineral particles. As the mineral particles are moved tangentially into the lower part of the flotation tank, the coarser mineral particles tend to be near the tank wall while the finer mineral particles tend to move into the central part of the tank. Air bubbles or lightweight synthetic bubbles are used to collect and lift the finer mineral particles to the upper part of the tank. The coarser mineral particles are recovered by using collection surfaces coated with a hydrophobic material.

Abstract

Apparatus uses engineered collection media to recover mineral particles in a slurry. The apparatus has a tumbler cell and a rotation device to rotate the tumbler cell. The tumbler cell has a container to hold a mixture of the engineered media and the slurry containing the mineral particles. The container is turned such that at least part of the mixture in the upper part of the container is caused to interact with at least part of the mixture in the lower part of the container. As such, the contact between the engineered media and the mineral particles is enhanced. The surfaces of the engineered media are functionalized with a chemical having molecules to attract the mineral particles to the surfaces so as to form mineral laden media. After the mineral laden media are discharged from the tumbler cell, the mineral particles can be separated from the engineered media by stripping.

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 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 attaching 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.
