乙二胺磷酸盐为东川矿务局中心试验所于1974年研制的一种有机调整剂,对落雪的氧化铜矿石效果突出。1975年工业试验成功,1980年正式应用于工业生产。近年来矿山向深部采掘,矿石铜氧化率逐渐下降。生产实践表明,对氧化硫化混合铜矿石,添加乙二胺磷酸盐浮选指标提高幅度有所减小,尤其是对氧化率低于15％的铜矿石,由于硫化铜相回收率明显降低,全铜回收率反而下降。生产实践还表明,随着矿石铜氧化率降低,乙二胺磷酸盐最佳消耗量
Ethylenediamine phosphate is an organic modifier developed by Dongchuan Mining Bureau Central Laboratory in 1974, which has prominent effect on the snowing copper oxide ore. Successful industrial test in 1975, formally applied to industrial production in 1980. In recent years, mining to the deep mining, ore copper oxidation rate decreased. The production practice shows that the increase rate of flotation index of ethylenediamine phosphate is reduced for oxidatively-sulfurized mixed copper ores, especially for copper ores with an oxidation rate of less than 15%, since the recovery of copper sulphate phase is obviously decreased , Copper recovery but decreased. Production practice also shows that with the ore copper oxidation rate decreased, the best consumption of ethylenediamine phosphate
