摘要
研究了采用热压氧化浸出新方法从贵州某炭质页岩型钒矿石中提取钒。试验结果表明:在矿石细度为-0.15mm占70%、浸出剂GZ-1#用量为矿石质量的15%、液固体积质量比1︰1、浸出温度180℃、浸出氧气压力0.8MPa、浸出时间3h条件下,钒浸出率达90.83%。该新方法不需对矿石进行焙烧,浸出剂用量低,浸出时间短,无环境污染和资源浪费等问题。
Leaching ;f vanadium from carbonaceous shale navajoite from Guizhou by oxidizing and heating pressure has researched. The experiment results showed that at the conditions of ore particle size of -0.15 mm accounting for 70%,leaching agent GZ-1# dosage of 15 %,liquid to solid ratio of 1 ： 1,leaching temperature of 180 ℃ ,oxygen pressure of 0.8 MPa, leaching time of 3 h,the vanadium leaching rate reached 90.83%. The method don not need roast ore,reagents dosage were lower, leaching time was shorter, the problems of environmental pollution and resources wasted could be avoided.
