| Abstract: | The paper analyzes the reason of zinc powder re-dissolution in alkali metallurgy process and the influence of various factors on zinc powder re-dissolution. It was found that the amount of zinc powder re-dissolution can be reduced by reducing temperature, shortening solid-liquid separation time, decreasing stirred speed and liberating fine grain size zinc powder by electrolysis method. |
