| titleOfInvention | A kind of method preparing ammonium perrhenate |
| abstract | The present invention relates to Rhenium recovery and utilize technical field, it is specifically related to a kind of method preparing ammonium perrhenate, prepare ammonium perrhenate from the rich Rhenium recovery liquid purification that obtains of enrichment of lean rhenium stock solution, richness Rhenium recovery liquid through concentrating under reduced pressure, heat resolve and dissolving crystallized is prepared ammonium perrhenate, said method comprising the steps of: the first step, concentrating under reduced pressure prepares condensing crystallizing body, second step, heat resolve collects rhenium heptoxide solid, the 3rd step, dissolving crystallized preparing ammonium perrhenate, the 4th step carries out molybdenum-rhenium recovery.The inventive method can realize molybdenum-rhenium and efficiently separate, and prepares high-grade ammonium perrhenate；With lean rhenium stock solution as raw material, raw material is extensively easy to get, it is achieved that resource comprehensive utilization utilizes. |
