无捕收剂体系中,硫砷铜矿在低电位下氧化,表面主要发生Cu氧化形成Cu2+进入溶液的过程,但氧化后的Cu2+是否形成Cu(Ⅱ)相沉积于矿物表面存在争论.另外,由于硫砷铜矿在较高电位下氧化,表面主要发生As和S的氧化,As氧化形成,但S氧化形成S0还是也存在争论.VELASQUEZ等[28]的研究也显示,硫砷铜矿在较高电位下氧化,表面形成CuO, As2O5,As2O3,CuSO4及相应的Cu(OH...中形成表面产物的不完全可逆还原反应相关.该循环伏安曲线与VELASQUEZ等[28]的测定结果基本一致,但与PLACKOWSKI等[21]的测定结果存在一定的差别,这可能与所采用硫砷铜矿样品中杂质的类型及含量不同有关. 图2 硫砷铜矿在pH 9.2的电解液中的循环伏安曲线 Fig. 2 Cyclic voltammogram of enargite......
