Method and Process of Treatment of Selenium Containing Material and Selenium Recovery

摘要

The method and process of treatment of selenium containing materials, including, but not limited to, different adsorbents, membranes, filters, bioreactor sludge obtained from water treatment, waste electronic devices, material obtained from mineral processing, different industrial wastes, metallurgical wastes, which allow reduction of total selenium content in the material and selenium recovery have been developed.

主权项

1) The method and process of selenium recovery from a solid material, which contains selenium in any form, such as elemental selenium or selenium compounds, using reaction with alkaline and sulfide solutions, followed by solid/liquid separation and selenium recovery from the liquid phase obtained by precipitation as elemental selenium or selenium compounds.
