中文摘要: 研究了粗硒的提纯工艺,分别考察了粗硒粒度、反应温度、反应时间、亚硫酸钠浓度以及反应过程中加入氢氧化钠对浸出效果的影响。结果表明,浸出过程中加入一定量的氢氧化钠具有可行性。采用亚硫酸钠浸出 - 硫酸还原,精硒主品位达到 99.98%。
Abstract:The effects of particle size, reaction temperature, reaction time, concentration of sodium sulfite and addition of sodium hydroxide on the leaching effect of crude selenium were investigated. The results show that adding a certain amount of sodium hydroxide in the leaching process is feasible. The main grade of selenium was 99.98% by sodium sulfite leaching and sulfuric acid reduction.
