| 摘 要： | 研究了从酸性加压浸出液中采用溶剂萃取法提取钼工艺，考察了萃取剂浓度、改质剂浓度、萃取相比、萃取时间等对钼萃取率的影响。试验结果表明，在有机相组成25％N235＋5％异辛醇＋磺化煤油，O／A=3／1，混合时间3min的条件下，钼的萃取率可达到98％以上；负栽有机相采用20％的氨水反萃，O／A=1／3．在两级逆流萃取的条件下钼反萃率超过98％。

| Abstract: | The technology of extracting molybodenum from acid pressure leaching solution adopting solvent extraction method was researched. The effects of extractant concentration, modification agent concentration, phase ratio and extraction time on the extraction rate of Mo were investigated. The tests result showed that the extraction ratio of Mo could reach above 98% at the condition of the organic phase containing 20% N235, 5%Isooctanol and Kerosene with O/A of 1/3, and the mixing time of 3 rain. When the loaded organic reagent was stripped with 20% ammonia, the stripping ratio of Mo was more than 98% after two-stage stripping with O/A of 3/1. |
