| The present invention relates to a method for manufacturing a high-grade metal concentrate by eliminating arsenic. The method for manufacturing a high-grade metal concentrate according to the present invention is for separating arsenic-containing minerals including arsenic and target minerals comprising a useful metal in pulp, by a flotation of the pulp formed by crushing an ore comprising the useful metal and putting the pulverized ore into water for the flotation. The method for manufacturing a high-grade metal concentrate forms a calcium sulfoaluminate-based hydrate on the surface of the arsenic-containing minerals in the flotation process to hydrophilize the arsenic-containing minerals and separate the arsenic-containing minerals. | ||||||

| Uses of a method of producing small bubbles of gas in a liquid include gas transfer in airlift bioreactors and anaerobic digesters, and particle separation. The method uses a source of the gas under pressure, a conduit opening into a liquid and oscillating the gas passing along the conduit. The oscillation is effected by a fluidic oscillator, comprising a diverter that divides the supply into respect outputs, each output being controlled by a control port, wherein the control ports are interconnected by a closed loop. Separation of algae from water involves delivering a laminar flow of microbubbles in the range 10 to 100 µm diameter. Such bubbles also deliver a laminar flow in bioreactors that delivers enhanced liquid flow despite the small bubbles, which improves mixing and also enhances efficiency of gas exchange and retention of the bubbles in the reactor. In an anaerobic digester, the microbubbles strip waste gas and deliver nutrients. In particle separation, a pH-adjusting gas adjusts the pH in the boundary layer surrounding each bubble to inhibit repulsion between bubbles and particles. | ||||||
