Abstract

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.
