    Abstract: A reactor for aerating a fluid with a gas comprises a mixing tank (12) for the fluid and a centrally located vertical draft tube (13) submerged in the fluid to divide the mixing tank (12) into an inner chamber (21) and an outer chamber (23). The reactor further comprises a motor driven axial flow impeller (14) located in the draft tube (13) for circulating fluid downwardly through the inner chamber (21) and upwardly through the outer chamber (23). The reactor further comprises an external circuit for withdrawing a portion of the fluid from the mixing tank (12), aerating the fluid, and returning the aerated fluid to the mixing tank (12). The aerator is in the form of a venturi device (17).

    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 characterized 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 characterized 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: 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.
