    Abstract: The present invention relates to flotation of sulfidic copper-molybdenum- and gold-containing minerals. More specifically, the invention relates to sulfoxy reagent-assisted floatation for separating of sulfides of copper, molybdenum and gold from pyrite, marcasite, pyrrhotite, arsenopyrite, and other gangue minerals following aerating by an oxidizing gas and contacting by a sulfoxy reagent. To promote collection and flotation the feed mineral materials are preferably not contacted with an externally generated non-oxidizing gas to lower the dissolved molecular oxygen content prior to flotation.

    Abstract: A clarification system may comprise a channel having an inlet and an outlet, a length, bottom, and a height sufficient to contain a liquid having a depth. The clarification system may include one or more gas injectors disposed within the channel, configured to inject gas bubbles into a suspension flowing in the channel. In some embodiments, at least one gas injector injects gas bubbles having average or median size that does not exceed 100 microns in diameter. Some gas injectors inject bubbles having mean size below 50 microns. Some gas injectors inject gas via the precipitation of gas bubbles from a supersaturated liquid including a dissolved gas. Certain embodiments may be configured to form a quiet zone, typically near the top of the flowing suspension, in which turbulence may be minimized or substantially eliminated. Certain systems include a plurality of gas injectors disposed at different lengths along the channel.

    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.
