    Abstract: A low temperature process for separating bitumen from tarsands comprises slurrying tarsands in water at a temperature in the range of above about freezing to 35.degree. C., preferably in the range of 2.degree. to 15.degree. C., mixing said aqueous slurry with a conditioning agent for a time sufficient to release bitumen from tarsands and to uniformly disperse the conditioning agent on the bitumen, and subjecting the resulting slurry to froth flotation for recovery of a bitumen product and production of sand tails. The process can be integrated with dredge or dry mining of the tarsands wherein the tarsands are normally sheared by a rotary cutter or bucket wheel and slurried with water by a slurry pump under attrition mixing conditions, with waterjet mining of tarsands in open pits wherein the resulting slurry can be collected by mechanical equipment, slurry pumps or the like gathering equipment, the resulting slurry fed to a pipeline and the conditioning agent added to the slurry pipeline for mixing with the slurry, or with borehole mining of tarsands wherein high pressure jets of water or water with conditioning agent disintegrates the tarsands in situ for initial slurrying of the tarsands. The conditioning agent preferably is a flotation agent having the characteristics of kerosene, diesel or kerosene/diesel together with a frother having the characteristics of methyl-isobutyl-carbinol and can be mixed with the aqueous slurry by attrition scrubbing or by flotation cell mixing. The slurry may contain up to 70% by weight tarsands and normally is adjusted by dilution to 15 to 30% by weight tarsands in water prior to froth flotation in one or two stages.

    Abstract: A method of selectively recovering an arsenopyrite, pyrrhotite or like mineral from a material containing such a mineral and pyrite which includes the steps of providing a slurry of the material, adding a dialkyl (C.sub.3-8)-dithiophosphate to the slurry, passing a gas through the slurry to cause the mineral to be carried to the surface of the slurry and report in a first float concentrate, removing this concentrate from the slurry, activating the mineral remaining in the slurry by adding a suitable water-soluble copper salt to the slurry, adding a monoalkyl (C.sub.3-10)-dithiocarbamate to the slurry, passing a gas through the slurry to cause mineral to be carried to the surface of the slurry and form a second float concentrate, removing the second concentrate from the slurry and combining the first and the second float concentrates.

    Abstract: Pyritic sulfur is removed from coal or other carbonaceous material through the use of humic acid as a coal flotation depressant. Following the removal of coarse pyrite, the carbonaceous material is blended with humic acid, a pyrite flotation collector and a frothing agent within a flotation cell to selectively float pyritic sulfur leaving clean coal as an underflow.

    Abstract: A process is described for the mineral separation of rare earth metal compounds, such as bastnaesite, contained in oxidic minerals. The process is a froth flotation process utilizing a novel collector emulsion, which is an emulsified mixture of:a secondary amine modified sulphonated fatty acid,a high rosin containing tall oil fatty acid,an anionic petroleum sulphonate, anda high molecular weight primary amine.The collector emulsion mixture is added to the aqueous slurry of the comminuted rare earth metal compound containing oxidic mineral, which has been previously conditioned in a conventional manner. The conditioning reagents may include alkaline pH modifiers and gangue depressants such as citric acid, oxalic acid, sodium silicates and fatty acids.The rare earth metal compounds will be concentrated in the froth, and are separated in the conventional manner.
