Tellurium Recovery by Solvent Extraction from Copper Telluride Prepared with Copper Anode Slime AITranslate
Abstract AITranslate
Tellurium was enriched as copper telluride from copper anode slime. Tellurium and selenium were separated from chlorination leaching solution of copper telluride by solvent extraction, and tellurium was recovered. The results show that with 20% TOA＋20% octanol＋60% sulfonated kerosene （volume fraction） as the extractant,2 mol/L H2SO4 ＋HCl as the detergent and 200 g/L NH4 Cl solution as the stripping agent, tellurium can be effectively separated from selenium and copper. After stripping solution is reduced by sulfur dioxide or hydrazine hydrate,high purity tellurium powder is obtained.
