醚醇起泡剂是用石油加工付产品合成的。国外早已广泛使用。1978年10月,我矿与北京有色金属研究院、广州有色金属研究院合作用醚醇代替2号油进行选铜、选硫小型试验,1979年7～8月又进行了工业试验。这些试验表明,醚醇与2号油选别指标相似,选铜选硫用量分别减少30～40％、60～ Ether alcohol foaming agent is processed with petroleum products. Foreign has long been widely used. October 1978, I mine with the Beijing Institute of Nonferrous Metal, Guangzhou Nonferrous Metal Research Institute in cooperation with ether alcohol instead of No. 2 oil for copper, sulfur small test, 1979 July to August and another industrial test. These tests show that the ether alcohol and the No.2 oil selections do not like indicators, the election of copper were reduced sulfur dosage 30 ~ 40%, 60 ~
