WERKWIJZE VOOR HET TERUGWINNEN VAN ELEMENTEN MET VERSCHILLENDE WAARDIGHEDEN UIT AFVALWATER. |
摘要 |
<p>A method for stripping pollutant metals from sewage waters from ore-treatment installations is disclosed, which comprises the step of using, in a short-circuited electrode system through which the waters to be purified are flowed, a compound of an element which is other than the cathode metal and is more electro-positive than the anode element. Striking results are obtained by treating vanadium-containing sewage waters from gallium-ore treatment plants with silver sulfate in a copper-iron electrode system. The method can be employed to recover other transition metals from liquors which contain them.</p> |
