VERFAHREN ZUR STEUERUNG VON MANGANGEHALT IN EINEM ZINKLAUGUNGSYSTEM |
摘要 |
<p>A method and apparatus for precipitating manganese from acidic sulfate solutions, and more specifically from zinc leach solutions, without removing zinc. A zinc- and manganese-containing solution is treated with an SO2-O2 gas mixture at the appropriate pH and temperature, thereby causing manganese to precipitate as a trivalent and/or tetravalent manganese hydroxides and/or oxides that report to the leach residue or are removed separately from solution by solid/liquid separation. These trivalent and/or tetravalent manganese compounds may be used as oxidants in other parts of the leach circuit.</p> |
