Germanium slag recovery_ Industrial germanium recycling price_ Germanium containing waste recycling and refining manufacturer

Germanium slag is generally the waste containing germanium generated during industrial production and processing, also known as industrial germanium. Germanium slag generally appears in scenarios such as semiconductor equipment processing and non-ferrous metal smelting. The common preparation method of germanium residue is: chlorinate the germanium concentrate with concentrated hydrochloric acid to produce Germanium tetrachloride, remove the main impurity arsenic by hydrochloric acid solvent extraction, and then purify it twice by quartz tower distillation, and then wash it with high-purity hydrochloric acid to obtain high-purity Germanium tetrachloride. Hydrolyze Germanium tetrachloride with high-purity water to obtain high-purity Germanium dioxide. Some impurities will enter the hydrolysis mother liquor, so the hydrolysis process is also a purification process. After drying and calcining, pure Germanium dioxide is reduced with hydrogen in quartz tube of reduction furnace at 650-680 ℃ to obtain metallic germanium. Germanium slag is the main source of germanium containing waste recycling, and the sources of germanium containing waste recycling include germanium mud recycling, germanium stone recycling, industrial germanium recycling, germanium particle recycling, single crystal germanium recycling, germanium sheet recycling, etc. If you have any demand for germanium containing waste recycling, please call our 24-hour service hotline.
