Using new ion-exchange materials in the hydrometallurgy of rhenium

摘要

The possibility of using new ionites-anionite AN-105-12P and ampholite VP-18KR – to extract rhenium from thenitric-acid solutions formed in the hydrometallurgicalprocessing of molybdenite concentrates is explored. A two-stagesorptional setup for producing ammonium perrhenate on thebasis of these ionites is considered.
