| A method and an apparatus for the separation of the mineral components of a pyrite containing copper- molybdenum ore by flotation. The method comprises grinding the ore in the presence of soda ash in an open circuit to produce an aqueous ore slurry; subjecting the slurry to a collective flash flotation step (10) in the presence of soda ash and sodium sulphide to recover a first part of metal sulphides of the ore in the form of a first concentrate (Cl); subjecting the tailings (Tl) of the collective flash flotation step (10) to a grinding step (13) and to a collective rougher flotation step (14) to recover a second part of metal sulphides of the ore in the form of a second concentrate (C3); and subjecting the concentrate (Cl) of the collective flash flotation step (10) and the concentrate (C3) of the collective rougher flotation step (14) to a selection step (12) to separate molybdenite from the other metal sulphides of the concentrate. | ||||||

| The present invention is directed to methods that can be used in the enrichment of metal sulfide ores in desired minerals in cases where the ores have sulfide-containing gangues. The method involves adding an oxidant such as hydrogen peroxide to slurries prepared from the ores during, or immediately prior to froth flotation. | ||||||

| A process for decontaminating a medium polluted with metals and hydrophobic organic compounds (HOC) includes providing an acidic slurry of water, acid, chloride salt, surfactant, and the polluted medium. Flotation is preformed on the acidic slurry to form a HOC-rich froth and an HOC-depleted slurry and the froth is recovered. The slurry is separated to obtain a treated solid and a liquid effluent rich in metallic ions. Preferably, the process also includes recuperating the metals by chemical precipitation and/or electrodeposition to produce a treated solution. Also provided are a decontaminant having an acid, a chloride salt, and a surfactant as well as a chemical kit for decontaminating the polluted medium including the decontaminant in which the acid, chloride salt and surfactant can be mixed with polluted medium in the presence of water before removing at least a portion of the metals and HOC from the polluted medium. | ||||||

| The present invention generally relates to methods for purifying and/or concentrating compounds from or in solutions and/or mixtures. In one embodiment, the present invention relates to a method for purifying and/or concentrating a compound from a solution or mixture. In another embodiment, the present invention relates to a method for purifying/concentrating a compound from a solution or mixture that utilizes, in whole or part, foam purification and/or concentration. In still another embodiment, the present invention can be used to separate, concentrate and/or purify any material, including biological products and/or biomaterials, that can be selectively bound to a binding agent, thereby yielding a complex that will readily partition onto bubble surfaces in a foam. | ||||||

| L'arsénopyrite est séparée d'un mélange avec la pyrite par la mise en contact du mélange avec un agent sulfitique fournissant des ions HS03- à température élevée et un pH inférieur à 8 pendant un temps suffisant pour communiquer à l'arsénopyrite une propriété d'enfoncement sélective. Avec l'addition d'un collecteur, la pyrite est rendue flottante, permettant la flottaison de l'écume pour obtenir un concentré riche en pyrite et des résidus riches en arsénopyrite. | ||||||

The invention relates to a method of producing fatty acid esters of polyoxyalkylene glycerol ethers. The method comprises reacting an alkylene oxide or oxides directly with a mixture of a natural fat or oil, water and a catalyst. The method of the invention can avoid the complicatedness encountered in the prior art production processes and give polyoxyalkylene glycerol ether fatty acid esters excellent in surfactant performance. |
