中文摘要: 用硫化沉淀法有效地从次氧化锌渣酸浸液中实现了铟与砷、锑、锡的分离。研究了初始酸度、硫化物的选择及用量,反应时间等因素对分离过程的影响。试验表明:室温条件下,起始酸度为2.0mol/L的酸浸液,按理论值L3倍摩尔比加入ZnS,搅拌10min,锑、砷、锡沉淀率分别达100%、98%、93%,铟的损失率小于2%。
Abstract:An effective method of separation indium and arsenic,antimony,tin from the secondary zinc oxide slag acid lixivium has been achieved by sulphuration process.The effects of initial acidity,the sort and quantity of sulfide,the time of reaction are tentatively investigated.The results show that the removal rate of antimony,arsenic and tin is 100%,98% and 93%,respectively,the lost rate of indium is less than 2% under the following conditions: room temperature,initial acidity is 2.0 mol/L,ZnS is 1.3 times mole ratio than the theoretical,mixing time is 10 min.
