| 简介 |
FIELD : metallurgy.
SUBSTANCE : invention relates to hydrometallurgy of rare and noble metals, particularly to methods of concentrate receiving, containing rhenium and platinum, from its containing acid liquors. Method includes extraction of sulphides of rhenium and platinum by means of introduction into solution of sulfur-bearing reagent. After it is implemented separation of received sulphides of rhenium, platinum and its other compounds from solution and recovery of sulphides in gaseous medium. At recovery it is received concentrate of rhenium and platinum. Introduction of sulfur-bearing reagent into initial solution is implemented at mass correlation of sulfur-bearing reagent and dissolved rhenium and platinum from 26 up to75.
EFFECT : increasing of extraction ratio rhenium and platinum into concentrates.
