A plurality of collection surfaces 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 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 collection surfaces having the mineral particles attached thereon are caused to interact with liquid and supercritical carbon dioxide so that the mineral particles can be stripped from the collection surfaces. |

A hydrocarbon separation system and process to separate solvent from mixed fluids extracted from an underground formation. The separation system includes a main separation chamber, a reboiler circuit, and a multi-stage reflux circuit. The main separation chamber separates liquid inputs into bottom liquids and top vapours. The reboiler circuit separates bottom liquids received from the main separation chamber into purified solvent and a reboiler vapour fraction. The multi-stage reflux circuit receives the top vapours from the main separation chamber and separates solvent from the top vapours in two stages. The first stage separates a first reflux liquid from the top vapours, and passes the first reflux liquid to the main separation chamber. The second stage receives top vapours remaining in the first stage, separates solvent therefrom, passes the separated solvent to the main separation chamber, and exhausts any remaining vapours. |

El proceso integrado para recuperar metales valiosos a partir de mena de sulfuro incluye los pasos de clasificación en bruto 16 y cribado 24 / 28 de la mena aplastada. La corriente de menas gruesas clasificadas / cribadas se muele y ordena 20 para proporcionar una fracción de gruesos 34 adecuada para flotación de gruesos y una primera fracción de finos 38 adecuada para flotación. La fracción de gruesos adecuada para la flotación de gruesos se somete a una flotación de gruesos 36 para obtener así una ganga 42 y un concentrado intermedio 46. El concentrado intermedio se somete a molienda 48 para proporcionar una segunda fracción de finos adecuada para flotación convencional. La primera fracción de finos y la segunda fracción de finos se someten a una flotación convencional 40 para proporcionar un concentrado y relaves. Este proceso capitaliza la heterogeneidad natural de los yacimientos de sulfuro y utiliza tecnologías de reducción de clasificación en bruto, cribado y flotación de gruesos en una configuración multietapa para rechazar la máxima cantidad de ganga de desecho antes de la conminución de finos. |

A separation facility and process to separate a mixed fluid stream produced from an underground formation by means of an in situ solvent based hydrocarbon extraction process into separate process streams. The separation facility includes a first separation stage to separate any produced mixed fluids into at least a mixed water process stream and a heavy and light hydrocarbon process stream. There is a second separation stage to separate said heavy and light hydrocarbon process stream into a heavy hydrocarbon process stream and a bulk light hydrocarbon process stream. Then there is a bulk light hydrocarbon separation stage for separating said solvent from the balance of said bulk light hydrocarbon process stream. This stage may include the use of a two or more step separation to minimize energy consumption. Then there is a mixed water separation stage to separate said mixed water process stream into a lower density mixed hydrocarbon rich process stream and a higher density water process stream. Lastly there is a final hydrocarbon separation stage to separate at least some residual light hydrocarbons from said heavy hydrocarbon process stream. |

Organic compounds that are associated with production of nickel sulphide concentrates are a major cause of the generation of odours in flotation processing plants and in stock-piled concentrates. The present invention discloses a process for producing a mineral concentrate product that at is at least a substantially odour-free product from a mined material that comprises floating selected mineral particles from a slurry of the mined material and forming a wet concentrate in the form of a froth product slurry, which includes a collector in the form of an organic xanthate compound for adsorbing selected mineral particles and promoting the flotation of the mineral particles, and treating the froth product slurry with heat and the addition of one or more chemicals selected from the group consisting of nitrate, molybdate, activated carbon and mixtures thereof, to prevent residual organic xanthate compounds or mineral concentrates from being converted to odorous compounds. |

A tailings solvent recovery unit (TSRU) and a process for recovering paraffinic solvent from solvent diluted tailings derived from a bitumen froth treatment operation are described. The solvent diluted tailings are processed in order to recover certain compounds, such iso-paraffins or cyclo-paraffins, which are present in the paraffinic solvent previously added to the bitumen froth and which are preferentially retained within asphaltene-bitumen matrices with respect to other paraffins of the paraffinic solvent due to lower diffusivity. |

The method involves placing mixture in a flotation basin that is filled with water shifted in pulsation. A rubber is deposited on a sieve base to control the jerky shaking motion. The rubber is carried to a discharge opening due to the jerky movements, with changeable cross section, by which the rubber is precipitated in a reservoir below the sieve base. The rubber is removed by a discharge sluice for further utilization. A wood is delivered in a wood collecting container and is supplied to the further utilization. |
