提高湖南某钨矿选矿生产指标的试验研究

Experimental Study on Improving Production Indicators of a Scheelite Ore In Hunan

针对湖南某钨矿生产过程中出现的钨回收率低的问题,进行了相应的选矿工艺流程和药剂制度的试验研究,并将试验成果应用于工业生产。对含钨0.362%的原矿,小型闭路试验获得WO3品位69.10%、WO3回收率84.04%钨精矿。新工艺运用到现场之后,现场钨精矿WO3品位由63.25%提高到68.86%,WO3回收率由试验前70.21%提高到81.56%,效果比较显著,达到了提高生产指标的试验目的。

In view of the low recovery of tungsten in the production process of a tungsten mine in Hunan, the corresponding beneficiation process and reagent system study was carried out, and the industry application of the study was successful. For the primary tungsten ore of 0.362%,.the locked circuit test results indicated that a tungsten concentrate grade of 69.10% WO3 can be obtained with a recovery rate of 84.04% from the feed of 0.362% WO3. After the application of the new process in industrial process, significant beneficiation indicators obtained with the grade of tungsten concentrate increased from 63.25% to 68.86% and the recovery rate increased from 70.21% to 81.56%, and the purpose of improving tungsten recovery is achieved.
