摘要
针对某铀钼矿硫酸浸出液中钼、铀质量比大,杂质浓度高,分离困难的特点,根据不同离子交换树脂对铀、钼吸附能力不同,进行分步吸附,分别淋洗分离铀、钼的研究。确定了用D301树脂优先吸附钼,再用D311-A树脂吸附铀的工艺方法,并分别进行了动态吸附—淋洗试验研究。结果表明:浸出液经D301树脂吸附钼后,尾液中ρ(Mo)降至0.058g/L;载钼饱和树脂经氨水淋洗,淋洗合格液中ρ(Mo)达70 g/L,ρ(U)仅0.075 g/L,实现了钼、铀的有效分离。钼吸附尾液经D311-A树脂吸附—碳酸钠淋洗后所得淋洗液中ρ(U)达20 g/L,实现了铀的提取。该工艺流程无氯离子引入,工艺水可返回利用,有效避免了氯离子积累对工艺过程造成的不利影响,是分离铀、钼的一种行之有效的方法。
Separation of uranium and molybdenum from the leaching liquid by fractional adsorption and elution respectively was studied.The process of the D301 resin preferential adsorption of molybdenum,and D311-A resin adsorption uranium again was determined,and the dynamic adsorption — elution experiment was carried out.The results show that the ρ(Mo) of the tail solution fell to 0.058 g/L after adsorption by D301 resin,Saturated resin by ammonia leaching molybdenum,the ρ(Mo) reach 70 g/L,while the ρ(U) is only 0.075 g/L,the molybdenum and uranium is effectively separated.The tail solution of molybdenum after D311-A resin adsorption and sodium carbonate leaching,the eluent of ρ(U) came to 20 g/L.The process is an effective method to separation molybdenum and uranium,as without chloride ion can be introduced into the process,and the process water can return to use and avoid the negative impact by the accumulation of chlorine ion.
