Abstract: A method of producing enhanced coal combustion ash for use in pozzolanic applications or cement manufacture, in which the enhanced combustion ash has lower mercury content. A slurry is formed of the combustion ash and water and is subjected to froth flotation to form a mercury-enriched ash slurry and a mercury-depleted ash slurry. The product mercury-depleted ash slurry is isolated and may optionally be dried. The combustion ash may be pulverized prior to being used to form the slurry, reducing its mean particle size. The mercury-depleted combustion ash product has reduced levels of mercury and ammonia, and reduced particle size.

Abstract: 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.

Abstract: The invention provides a flotation process which includes the steps of providing a flotation mixture containing mineral values to be recovered and adding an activator to the flotation mixture, which activator may comprise a metal complex formed by a coordinating metal ion and a ligand. A particular aspect of the invention relates to the use of the metal complexes as activators. These complexes are stable over a wide pH range, which is not the case with other inorganic compounds of which the applicant is aware, such as zinc sulphate, copper sulphate and manganese sulphate. The ligand may have the structure R—(X)n, in which X may be selected from amines, carboxyls, phosphonates and sulphonates; R may be an organic group; and n may be 1 to 4. The ligand may be selected to be a multidentate ligand. The invention extends to an activator for use in a flotation process.

Abstract: A process for separating minerals of different mineralogical character. A milled slurry or flotation concentrate is subjected to a first conditioning step (20) followed by a first flotation step (30) followed by a second conditioning step (50) followed by a second flotation step (60). One of the conditioning steps is with an oxidising gas, the other of the conditioning steps being with a non-oxidising gas and an oxidisable surface modifying reagent. The process allows separation of mixtures of valuable minerals by tailoring both the first and second conditioning steps and first and second flotation steps to particular mixed mineral ores.
