    摘要： A method is disclosed for separating phosphate minerals from a mineral mixture, particularly from high-dolomite containing phosphate ores. The method involves conditioning the mineral mixture by contacting in an aqueous in environment with a collector in an amount sufficient for promoting flotation of phosphate minerals. The collector is a hydroxamate compound of the formula; wherein R is generally hydrophobic and chosen such that the collector has solubility or dispersion properties it can be distributed in the mineral mixture, typically an alkyl, aryl, or alkylaryl group having 6 to 18 carbon atoms. M is a cation, typically hydrogen, an alkali metal or an alkaline earth metal. Preferably, the collector also comprises an alcohol of the formula, R′—OH wherein R′ is generally hydrophobic and chosen such that the collector has solubility or dispersion properties so that it can be distributed in the mineral mixture, typically an alkyl, aryl, or alkylaryl group having 6 to 18 carbon atoms.

    摘要： A composition of and method for forming activated carbon with magnetic properties for magnetic separation of the activated carbon from a liquid being treated is disclosed wherein a solution iron magnetic precursor is intimately mixed or absorbed into a porous carbon precursor or mixed with a solution or meltable carbon precursor to form an essentially homogeneous mixture or solution that when dried and pyrolized forms activated carbon particles with magnetic material evenly dispersed throughout the activated carbon material. The activated carbon particles may be of fine particle size, even powdered, and still retain magnetic properties sufficient for magnetic separation. In a particular aspect of the invention, a carbon precursor of soft wood is soaked in a solution of a ferric salt, dried, pyrolized and activated.

A primary inlet (20) can be operatively connected to the reactor body (24) and can be configured to produce flow-through first spinning flow of a first fluid within the inner volume (28). A secondary inlet (22) can similarly be operatively connected to the reactor body (24) and can be configured to produce a second flow of a second fluid within the outer volume (30) which is optionally spinning.

    摘要： A method for enhancing hydrophobicity of high volatile bituminous coal and coals of a lower grade and for separating ash and sulfur (including pyritic sulfur) contaminants from coal in a floatation process. The method comprises the steps of grinding the coal to small particulate size, forming a slurry of the ground coal and mixing the slurry with at least one compound selected from the group comprising inorganic peroxy compounds, the preferred compound being oxone which is a mixture of potassium monopersulfate, potassium hydrogen sulfate and potassium sulfate. This slurry is allowed to react to condition the particulate coal and develop increased hydrophobicity for the coal while depressing the sulfur contaminants and ash during froth flotation.

    摘要： A novel process for separating high viscosity bitumen from tar sand. The process includes grinding the tar sand to obtain phase disengagement of the bitumen phase from the sand phase and thereafter using flotation techniques to obtain phase separation of the bitumen phase from the sand phase. Phase disengagement is assisted by using a suitable wetting agent such as sodium carbonate or sodium silicate during the grinding step, while the phase separation step is assisted by the inclusion of a promoter oil for the flotation step.
