【摘要】:研究从富铼渣中回收并制备铼产品的工艺路线,着重考察药剂浓度、相比、时间等对铼萃取—反萃的影响,并探索进行了结晶制备高铼酸铵试验。结果表明,经过压力浸出,铼的浸出率达98%以上;在优化试验条件下,铼萃取率可达99.98%,反萃率达到99%以上,一次结晶所得高铼酸铵纯度为98.7%。
[Abstract]:The technological route of recovery and preparation of rhenium products from rhenium rich residue was studied. The effects of concentration and comparison time on the extraction and stripping of rhenium were investigated. The results show that the leaching rate of rhenium is more than 98%, the extraction rate of rhenium can reach 99.98%, the back extraction rate is over 99%, and the purity of ammonium perrhenate is 98.7% after primary crystallization.
