以丁铵黑药为捕收剂，添加一种新型抑制剂 O,O-二(2,3-二羟基丙基)二硫代磷酸(DHDTP)对黄铜矿和方铅矿进行浮选，通过动电位和吸附量的测试，探讨抑制剂DHDTP与矿物的相互作用机理。浮选试验结果表明：在整个pH范围内，抑制剂DHDTP对黄铜矿的抑制作用很弱；在pH 6~10范围内，抑制剂DHDTP对方铅矿有很强的抑制作用。随着抑制剂DHDTP用量的增多，方铅矿的回收率迅速降低，而黄铜矿的回收率只有小幅度的降低。在DHDTP用量278 mg/L、矿浆pH 6的条件下，人工混合矿浮选得出的精矿中铜的品位和回收率较好，分别为24.08%和81%。通过动电位和吸附量的测试结果可知，DHDTP在方铅矿上的吸附能力明显高于黄铜矿的。

A novel synthesized reagent, O,O-bis(2,3-dihydroxypropyl) dithiophosphate (DHDTP), was investigated as depressant on the depression of chalcopyrite and galena, when ammonium dibutyl dithiophosphate (DDTP) was used as the collector in flotation tests. Zeta potential and adsorption measurement were performed to study the interaction between depressant and minerals. The flotation tests of two minerals show that DHDTP has slight depression on chalcopyrite in the whole pH range and strong depression on galena in the pH range of 6?10. When DHDTP dosage is increased, the recovery of galena decreases rapidly, while that of the chalcopyrite decreases slightly. The satisfied separation results of artificially mixed samples are that the copper grade and recovery rates of concentrate are 24.08% and 81%, respectively, when the pH is 6 with 278 mg/L DHDTP. Zeta potential and adsorption measurements show that DHDTP has more strongly adsorption capacity to galena than chalcopyrite.
