Recovers crude Selenium (99.9% Se) from the Selenious acid (H2SeO3) solution using SO2 Gas in the Circulation tank. Produces selenium products with a purity of 99.95% by melting the crude selenium from circulation tank at 320¡É Casts of silver anode after melting and refining the roasted slime is mixed with Flux in the TROF. Produces silver products by melting and casting silver crystals with a purity of 99.99% produced by electrolyzing the Ag Anode, which is produced during TROF. Extracts crude gold by dissolving the Ag slimes by nitric acid. Casts the gold Anode by melting crude gold produced in the leaching process. Produces gold products by melting and casting the Cathode with a purity of 99.99% by electrolyzing gold anode. Extracts PdO-Slime from Pd in the solution after eliminating gold from gold sand in Ag slimes in the leaching process. Produces Palladium products with a purity of 99.9% by oxidizing and reducing the extracted PdO-Slime in the concentration reaction. Produces platinum products with a purity of 99.8% by oxidizing and reducing Pt-Slime and extracting Pt from the gold electrolyte for gold electro-refining.
