Allocation of tellurium from difficult on structure of sulfuric acid solutions

As the main source of reception of tellurium serve electrolytic copper refinery slimes. In the conditions of manufacture expansion and transition on technology decopperizing slimes by pressure leaching O 2 -H 2 SO 4 media, the solution (decopperized product) becomes the basic concentrator of tellurium. Extraction of tellurium from a decopperized (pressure-leached) liquid products is considered. The method allows to raise percent of extraction of tellurium from initial raw materials and to enrich pressure-leached solid product with precious metals.
