电化学调控浮选在梅山选矿厂的应用研究

介绍了DH-1#电化学调整剂在梅山铁矿的应用研究情况。通过实验室试验，找到在原矿含硫为3%时，电化学调控浮选的适宜药剂条件为DH-1# 150 g/t，乙基黄药40 g/t，2#油100 g/t。在此基础上开展了工业试验，获得了硫精矿S品位39.03%、尾矿S品位0.440%、S回收率78.53%的选别指标。使用DH-1#电化学调整剂调控浮选，可以节省乙基黄药捕收剂用量58%以上，每年可以产生349.562万元的经济效益。

Application of Electrochemical Regulation and Control of Flotation in Meishan Concentrator

The paper describes the test on the application of DH-1# electrochemical regulator in Meishang Iron Mine.It was found through laboratory test that, for a ROM ore containing 3% sulfur, the suitable conditions for the electrochemical regulation of flotation was 150 g/t DH-1#, 40  g/t ethyl xanthate and 100 g/t 2# oil.On this basis, an industrial test was conducted and obtained a sulfur concentrate grading 39.03% at a sulfur recovery of 78.53% and sulfur tailings grading 0.440%. The application of DH-1# electrochemical regulator in regulating and controlling the flotation can save the dosage of ethyl xanthate used as the collector by over 58%, enabling an annual economic benefit of 3.49 562 million.
