【摘要】:研究了從含高濃度鎳鈷合金渣酸浸液中萃取脫除低濃度鈣,考察了鈣離子去除的影響因素。試驗結果表明:以皂化率35%的10%P204+90%260#煤油為有機相,在水相pH=5.0、Vo∶Va=1∶2、萃取時間3min、溫度25℃條件下,Ca~(2+)單級萃取率達80%,Co~(2+)、Ni~(2+)單級萃取率分別為27%和9%;在此基礎上,通過3級逆流萃取,Ca~(2+)質量濃度降至1mg/L以下,達到生產高品質硫酸鈷、硫酸鎳產品所需料液對鈣離子的要求。
[Abstract]:The extraction and removal of low concentration calcium from acid leaching solution containing high concentration of nickel and cobalt alloy slag were studied, and the influencing factors of calcium ion removal were investigated. The experimental results show that the single-stage extraction rate of 10%P204 90 & 0# kerosene with saponification rate of 35% is 27% and 9%, respectively, under the conditions of water pH = 5.0%, extraction time 3 min, temperature 25 鈩,
