<p>A device for intermittently supplying powder material (65) to a plurality of feed pipes (52) for feeding batches of the powder material (65) to different areas of a molten electrolyte (5) in a metal electrowinning cell comprises an arrangement (54, 55, 56a, 56b, 57, 58) for metering quantities of powder material and for intermittently dropping the metered quantities over at least one inclined and/or upright dividing surface (51), for instance having a conical or pyramidal shape. Each metered quantity of the powder material (65) is divided as it drops over the dividing surface(s) (51) into a plurality of batches which correspond to said plurality of feed pipes (52) and which are directed to said corresponding feed pipes (52).</p> |
