    摘要： A process for separating zinc from a feedstock containing a mixture of metals and metal compounds. The process includes leaching a zinc-containing feedstock with a concentrated basic solution, optionally diluting the slurry with an amount of water sufficient to reduce the viscosity of the slurry thereby facilitating separation of a pregnant liquor containing dissolved zinc from insoluble materials, separating the insoluble materials from the pregnant liquor, and precipitating zinc oxide from the pregnant liquor by adding an anti-solvent to the pregnant liquor. The described process also provides for recycling of the basic solution and the anti-solvent.

    摘要： Disclosed is a method for treating in a continuous manner an aqueous solution containing ions of a given type in order to remove these ions from the solution. According to this method, the aqueous solution containing the ions to be removed is first neutralized if it is acidic. Then, it is contacted with a metal salt which is sparingly soluble in water and has a very strong affinity to react with the ions to be removed to form therewith another salt which is insoluble in water, for a period of time sufficient to allow this other salt to be formed and precipitate. This method is very efficient and can be used, by way of example, for removing chromium ions from an industrial waste water, using barium carbonate as sparingly soluble salt.

    摘要： A container including a top wall, the top wall defining a container first aperture and a container second aperture. A first and a second lid are provided. The first and second lid are configured so as to be each movable between a lid closed position and a lid opened position for selectively blocking and freeing respectively the container first and second apertures. A lock is configurable between a lock first configuration and a lock second configuration. In the lock first configuration, the container first lid is locked in the closed position by the lock and the container second lid is freely movable between the opened and closed positions. In the lock second configuration, the container second lid is locked in the closed position by the lock and the container first lid is freely movable between the opened and closed positions.
