摘要: 采用广西大学研制的新型有机抑制剂GZT,进行了降低长坡选矿厂铅锑精矿杂质含量、提高精矿铅锑品位的实验室小型试验和工业试验。试验结果表明,GZT是一种非常有效的硫化矿选择性抑制剂,工业试验中将长坡选厂铅锑精矿的铅+锑品位提高了9.61个百分点,铅锑精矿中的锌含量降低了2.97个百分点,同时铅和锑的回收率分别提高了4.75和4.19个百分点,使长坡选矿厂铅锑精矿品位偏低的问题得到了明显改善。

Abstract: GZT, a new organic depressor developed by Guangxi University, was used in the laboratory and industrial tests for reducing the impurity and improving the grade of Changpo Concentrator's lead-antimony.The result proved that GZT is a very efficient selective depressor for sulfide ores.Its application in the industrial test raised the lead + antimony grade of the concentrate by 9.61 percentage points, and reduced the zinc content of the concentrate by 2.97 percentage points, raised the lead and antimony recoveries by 4.75 and 4.19 percentage points respectively, solving the problem of low grade of the lead-antimony concentrate of Changpo Concentrator.
