摘要
研究了采用"氯盐浸出-中和-浓碱转型"工艺处理锑铋复杂物料,重点考察了氯离子浓度、硫酸浓度、液固比、反应温度、反应时间等几个因素对氯盐浸出的影响。研究结果表明在氯离子浓度为100g.L-1、硫酸浓度100g.L-1、液固比5:1、温度80℃、时间3h的最优工艺条件下,获得氧化铋含铋高达86.82%,杂质锑铜分别低至0.09%、0.25%,可作为优质原料进入生产系统,取得了满意的效果。
The technical process of chlorate - neutralization - strong alkali transformation is used to treat complex antimony and bismuth materials. Emphasize on the chlorate leaching inflenced by chloride ion density, acid density, solid - liquid ratio, reaction temperature, reaction time. Research result improve chloride ion density at 100g · L- 1, acid density at 100g· L- 1 ,solid- liquid ratio at 5 ： 1, temperature at 80℃, and 3 hours reaction time is best process condition. 86.82% grade Bismuth oxide could be got, copper and antimony inpurities content will be 0.09% ,0. 25%, under this best condition. High grade Bismuth oxide as high quality raw material could be used in production system, and satisfied result could be achieved.
