Treatment Methods for Complicated Materials Containing Selenium, Tellurium and Precious Metals AITranslate
Abstract AITranslate
Advantages and disadvantages are summarized of the conventional treatment methods for complicated materials containing selenium,tellurium and precious metals. The improved process in a Russian precious metal refinery and its efficiency is emphatically introduced, including leaching of initial materials in NaOH solution to enrich precious metal in alkali leaching residue, step-by-step adjustment of alkali leaching solution pH to precipitate and separate base metals such as selenium and tellurium,precious metal replacement and removal from mother liquor, and mixing smelting of alkali leaching residue and replacement product. Using the improved process, both precious and base metals are effectively recovered, and displacer consumption is also reduced during subsequent mother liquor replacement.
