    Abstract: A method of extracting targeted metallic minerals from ores that contain sulfide metallic minerals along with oxide minerals, carbonate minerals, silicate minerals, halide minerals or combinations thereof. In the method, an ore slurry containing the metallic mineral in oxide, carbonate, silicate or halide form is provided. The slurry is activated by adding sodium thiosulfate and sodium metabisulfite, whereby the targeted metallic mineral forms an intermediary metal complex with the sodium thiosulfate and sodium metabisulfite. One or more metal release components are introduced into the ore slurry; whereby the targeted metallic mineral is released from the intermediary metal complex to form a metal sponge. This metal sponge is then subjected to a flotation process, whereby the targeted metallic mineral is drawn out of the ore slurry and thereby extracted from the ore.

    Abstract: A flotation cell for separating hydrophobic particles from hydrophilic particles uses a mixer (1) with an air inlet (8) and slurry feed (7) to form a bubbly mixture in a u-tube mixer (4, 5, 6) and feed the mixture into a separation vessel (2). Plant cost and operating efficiencies are optimised by gravity feed of slurry and admitting air at atmospheric pressure. The separation vessel (2) has an upper inclined plate (9) which guides the froth layer (33) containing the hydrophobic particles to an overflow launder (11) without any significant turbulence or change in direction optimising the retention of hydrophobic particles in the froth, while the hydrophilic particles drop down in the liquid layer (34) guided along a lower inclined plate (24) to a tailings outlet (14).

    Abstract: A bitumen recovery process is provided which includes the step of providing a bitumen froth or a component derived from the bitumen froth as a feed material, wherein the bitumen froth is produced in a primary separation process from a slurry comprising oil sand and water. Further, the process includes the step of subjecting the feed material to froth flotation in a column flotation cell in order to recover a bitumen product from the feed material. Preferably, the froth flotation cell includes an underwash zone, wherein a bitumen-rich fraction of the feed material is passed through the underwash zone as the bitumen-rich fraction rises within the column flotation cell.

    Abstract: A process of separating at least one mineral, e.g. silica, from an aqueous medium, e.g. one containing iron ore, by froth flotation using cationic alkyloxyalkaneamine collectors free of acrylonitrile is described. Alkyloxyalkaneamines free of acrylonitrile may be made by reacting an alcohol with an alkenenitrile having at least 4 to 13 carbon atoms. This process produces branching on the third carbon from the nitrogen of the resulting compound, e.g. 3-hexoxypentaneamine. In addition to the absence of acrylonitrile, the alkyloxyalkaneamines give better selectivity than some conventional etheramines.

    Abstract: A sequential flotation process for the separation of components of an ore containing sulfides of copper and molybdenum involves initially effecting selective flotation of the copper component directly from the ore by conditioning the ore with a combination of a source of bisulfite ion and causticized starch to produce a conditioned ore having a pH between approximately 5.2 and 6.2, and thereafter treating the conditioned ore with a collector selected from the group consisting of dialkyl dithiophosphates and alkyl dithiophosphinates.

    Abstract: This invention provides a process for the beneficiation of phosphate ores having a magnesia-rich carbonate-containing gangue and a silica-containing gangue, which process comprises subjecting the phosphate ore particles to controlled attrition to remove at least a portion of the magnesia-rich carbonate-containing gangue; and subjecting the phosphate ore resulting from attrition to a plurality of flotations to remove the remaining magnesia-rich carbonate-containing gangue and the silica-containing gangue and to recover a concentrated phosphate product, the flotations including sequentially a phosphate flotation, a silica flotation and a carbonate flotation. Alternatively, the controlled attrition can be employed after the silica flotation and prior to the carbonate flotation.
