    Abstract: A reactor for introducing a gas into a fluid comprises a mixing tank (12, 43) for the fluid and a partition means (13, 45) for dividing the tank into at least two chambers (21, 89) and (23, 91). The reactor further comprises a first pump means (14, 47) located in one of the chambers for circulating the fluid downwards in one chamber and then upwards in the other chamber and an aerator assembly (29, 49) for aerating a sidestream of the fluid and introducing the aerated fluid into the tank for mixing the aerated fluid with the circulating fluid in the tank. The aerator assembly (29, 49) comprises a bank of venturi aerators (38, 57) each having an aerator inlet; an aerator outlet; and a constriction intermediate the aerator inlet and the aerator outlet for creating a region of reduced pressure in the fluid, the constriction being elongate in a section transverse to the direction of flow of the fluid through the constriction; and a means for introducing the gas into the constriction to aerate the fluid.

    Abstract: A method and an apparatus for producing metals and metal alloys from metal oxides in a metallurgical vessel containing a molten bath having a metal layer and a slag layer is disclosed. The method is characterised by injecting a carrier gas and a solid carbonaceous material and/or metal oxides into the molten bath from a side of the vessel that is in contact with the molten bath or from above the molten bath so that the solids penetrate the molten bath and cause molten metal to be projected into the gas space above the molten bath to form a transition zone. The method is also characterised by injecting an oxygen-containing gas into the gas space to post-combust reaction gases released from the molten bath into the transition zone.

    Abstract: A method of separating potassium chloride and sodium chloride from a heated solution of these salts, such as a solution obtained from potash ore, to recover potassium chloride from the ore is disclosed. The method includes a combination of steps of (a) extracting water from a heated solution containing potassium chloride and sodium chloride using a membrane system and (b) subsequently cooling the solution discharged from the membrane system, whereby steps (a) and (b) make it possible to selectively recover potassium chloride and sodium chloride from the solution.

    Abstract: Un método para separar cloruro de potasio y cloruro de sodio a partir de una solución calentada de estas sales, como por ejemplo una solución obtenida a partir de mineral de potasa, para recuperar cloruro de potasio del yacimiento. El método incluye una combinación de los pasos siguientes: (a) extraer agua de una solución calentada, que contiene cloruro de potasio y cloruro de sodio, utilizando un sistema de membrana; y (b) enfriar posteriormente la solución descargada del sistema de membrana, por lo cual los pasos (a) y (b) hacen posible recuperar selectivamente cloruro de potasio y cloruro de sodio a partir de la solución.
