| 1339337 Froth flotation ENGELHARD MINERALS & CHEMICALS CORP 30 Nov 1971 55420/71 Heading B2H A method of recovering slimed non-sulphide mineral values from an aqueous ore pulp comprises floating the valuable ore from gangue together with another non-sulphide solid in the presence of an anionic collector to form a bulk float product, removing water from said product, adding an alkaline dispersant thereto, aging the resulting mixture, adding water to the aged mixture to form a pulp, and without adding a collector reagent; aerating the pulp, thereby concentrating the valuable mineral or the non-sulphide solid in the tailings, and the other solid in the froth. Both the valuable mineral and the other non- sulphide solid may be constituents of the same ore or the said solid may be added to a pulp of the valuable mineral to assist in the flotation of the latter in the first stage of the process. The water may be removed from the bulk float product by filtering to give a product having a solids content of at least 50%, and aging may be carried out at ambient temperature for at least 12 hours. The valuable mineral may be cassiterite, pyrolusite, scheelite, anatase, rutile, zirconium or iron oxides, nickel ores, or elemental Au, Ag, Pt or Pd. The other non-sulphide solid may be calcite, fluorite, baryte, dolomite, apatite, sulphur or powdered polyethylene, polypropylene, polyvinyl chloride or polyamide. Suitable dispersants include sodium silicate, lithium carbonate, sodium hexametaphosphate, sodium tripolyphosphate and tetrasodium pyrophosphate. Suitable anionic collectors include oleic acid, tall oil acids, sulfooleic acid; soaps thereof, and mixtures with hydrocarbon liquids such as fuel oil and petroleum sulphonate salts. | ||||||

| 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. | ||||||

| Techniques for paraffinic solvent recovery from a high paraffin diluted bitumen can include supplying the high paraffin diluted bitumen to a paraffinic solvent flashing apparatus to produce a flashed paraffinic solvent component and a diluted bitumen underflow component; and returning a portion of the diluted bitumen underflow component into the high paraffin diluted bitumen with operation conditions selected to reduce asphaltene precipitation in the paraffinic solvent flashing apparatus. The flashed paraffinic solvent component can contain residual light end bitumen contaminants that increase solubility of asphaltenes and the paraffinic solvent recovery techniques can include removing a portion of the residual light end bitumen contaminants from the flashed paraffinic solvent component to produce a recovered paraffinic solvent which can be reused in the paraffinic froth separation operation at the given solvent-to-bitumen ratio range to maintain precipitation of a given concentration range of asphaltenes. | ||||||
