Experimental Study on Reducing Molybdenum by Washing N1923 Loaded Organic Phase with Waste Ammonia Water AITranslate
Abstract AITranslate
In the loaded organic phase extracted by N1923+isooctanol+sulphonated kerosene system,the low W/Mo ratio was the key factor limiting the separation efficiency of evaporative crystallization of W/Mo in the subsequent strip liquor.The process of eluting molybdenum from N1923 loaded organic phase by using workshop waste ammonia water as detergent to improve the W/Mo ratio was studied.The effects of pH value,reaction temperature,reaction time,and water to oil ratio on molybdenum elution rate were also investigated.The results show that under the conditions of pH=9.0,reaction temperature of 25℃,reaction time of 25 min,water to oil ratio of 4∶1,and standing time of 10 min,the unipolar elution rate of molybdenum reaches 88.18%.The secondary countercurrent washing of the eluted organic phase is found to have little effect on the elution rate of molybdenum with the increase of washing times.Using workshop waste ammonia water to wash the N1923 loaded organic phase to improve the W/Mo ratio is economically feasible,environmentally friendly,simple and effective,with high molybdenum elution rate and less tungsten loss.This study has certain reference significance for the separation of tungsten and molybdenum in the N1923 loaded organic phase.
