Recovery of rhenium in hydrometallurgic processing osmium-containing process-suitable materials of sulphide-copper ores

Article preview

Incidental concentrating of valuable elements in processing sulphide-copper ores yields supplementary semi-products enriched  with  osmium, rhenium, and  selenium.  Peculiar features of processing properties of rhenium, radiogenic osmium, and selenium are shown in this paper, as well as concentrators for rare microelements and ways of their extraction.

Study of the electrochemical behaviour of selenium in biselenium electrolytes

Article preview

A thermodynamic analysis of the system Se – H 2 O was prospect. Plotted dependences the concentrations of selenium oxyanions from the pH of the solution and polarization graphs for various materials of the anode. Draw conclusions about the regularities of selenium electroextraction from selenium solutions.
