Operation of mercury-cathode cells

摘要

A method for reducing the aqueous dispersion present in the amalgam being fed to a mercury cell which comprises reducing the velocity of amalgam stream at one or more stations along the amalgam flow where the amalgam enters a substantially static pool of amalgam which is itself covered by a layer of an aqueous phase, e.g., at lutes located at the exit of the cell, the exit of the denuder, the entry to a pump tank or pump, and the entry to a wash box feeding to the cell. The invention is advantageous for reducing chloride entrainment in the amalgam fed to the denuder and for reducing the build-up of thick mercury deposits on the baseplate of a mercury cell.
