摘要
介绍了一种新型浮选药剂——二乙基磷酸酯基二硫代甲酸钠的研制及捕收黄铁矿、方铅矿的行为,并与丁基黄药和硫氮九号相比较。结合量子化学(CNDO/2方法)计算结果,对二硫代甲酸盐系列捕收剂的结构与性能关系作了讨论。
A new type of flotation reagent,sodium diethyl phosphonyl dithiocar-bonate(C_2H_6)_2P(O)C(S)SNa(EDPC)was synthesized.Its behavi-our as collector in pyrite and galena flotation was tested and comparedwith butyl xanthate(BX)as well as diethyl dithiocarbonate(DDTC).It was shown that EDPC was probably a more selective collector thanBX and DDTC.The relationship between reactivity and selectivity of thesereagents was well explained by HSAB role(Hard Soft Acid Base role)and quantum chemistry calculation results(CN...
