The deep-processing technology research of high-purity ammonium rhenate was done from accompan-ying rhenium in a certain copper mine in the production of low concentration of ammonium rhenate. The extraction method was adopted to get high-purity ammonium rhenate in this experimental study ,the purity of the product was increased to more than 4 N from 2 N,the content of total impurity is< 0. 01%,the recovery rate is as high as 98. 8%. Thus, the blank of the accompanying rhenium resources processing areas was filled ,the scare metal refining in the field of technology was pushed ,the product added value was improved ,it had great economic significance and social benefits.
