Research of sulfidation of technogenic materials with sulfur

The research is about way treatment of rare metal containing raw materials. There are given the problem of solid-sulfidation of oxidized technogenic wastes Theoretical study of sulfidation process of osmium and rhenium compounds Experimental studies of the behavior of osmium and rhenium at sulfidation slime cake and dust in a wide temperature range Behavior and distribution of osmium and rhenium at sulfidation process of slime cake and dust. The developed method has a high degree of extraction of rhenium (99%) and osmium (95-96%) and the use of cheap reagent comprising parallel recovery / recycling and lead technological products and elemental sulfur oil industry in Kazakhstan.
