| Abstract: | Water leaching-neutralizing processes have been introduced to prepare TeO2 from alkaline residue of gold and silver production, and the fineness of recovered TeO2 is more than 99.5 %. Moreover, alkali dissolution and electrolysis have been introduced to prepare tellurium, and the fineness of recovered tellurium ingot is more than 99. 995 %. This is a method with high quality propery of the product, uncomplicated equipment, simple flowsheet, green environmental protection, and its economic benefits are also obvious. |
