Study on New Purification Technology of Industrial Molybdenum Oxide AITranslate
Abstract AITranslate
To solve the problem that calcium molybdate and low-valence molybdenum in industrial molybdenum oxide are insoluble in ammonia water and there are other impurity elements in the leaching solution,a new efficient and simple process was studied,mainly including the two parts of leaching and extraction.The effects of Na2CO3dosage,leaching temperature,leaching time and liquid-to-solid ratio on molybdenum leaching were investigated.The extraction and stripping conditions were explored by changing phase ratio,extraction time,extraction stage,stripping agent concentration and stripping stage.The results show that under the conditions of Na2CO3dosage coefficient 1.16,leaching temperature 140℃,leaching time 3 h,and liquid-solid ratio 4∶1,the molybdenum leaching effect is the best,and the leaching rate is over 99%.The optimum technological conditions of extraction and stripping are as follows:the extraction conditions are organic phase composition of 15%N235+10%octanol+75%kerosene,pH value of 3.2,extraction time of 6 min,phase ratio of 3.5∶1 and 4-stage countercurrent extraction;the stripping conditions are 13.64%NH3·H2O as the stripping agent,stripping time of 10 min,phase ratio of 5∶1 and 2-stage countercurrent stripping.Both the extraction rate and stripping rate of molybdenum are over 99%under the above conditions.This technology has high utilization efficiency and low loss of molybdenum resources,and the concentration of molybdenum solution can reach 173.45 g/L after purification.
