| 摘 要： | 以煤为还原剂,对铬盐生产中产生的废渣进行还原,按铬渣∶大河煤∶石英砂配比为25∶5.5∶2.5冶炼铬盐废渣时,冶炼情况良好,可以回收85%左右的铬。高温碳还原法可有效处理无钙焙烧工艺产生的铬盐废渣。

Recovery of Valuable Metals from Chromium and Vanadium Slag |

| Abstract: | Slag generated from the production of chromium salts was reduced with coal as reductant. With the chromium slag, coal from Dahe place and quartz sand at the proportion of 25∶5.5∶2.5 in the test, 85% chromium was recovered from the slag after metallurgical process. It is concluded that the process of high temperature carbon reduction is effective for processing the chromium slag from calcium?free roasting process. |
