Tellurium is the indispensable base material of semiconductors in solar panels. Traditional tellurium recycling, a highly complicated separation process, has exhausted reagents and energy sources whilst producing waste residue and water containing multitudinous heavy metal that is hugely harmful to the ecological environment. A clean and eco-friendly vacuum distillation-directional condensation treatment was investigated for its potential to recycle tellurium from tellurium-rich lead anode slime (TLAS). The optimal distillation temperature and response time conditions of 1173 K and 50 min were obtained based on a large number of experiments. Gasification results indicated that under the optimal conditions of distillation temperature 1173 K, constant temperature time 50 min, and system pressure 5–15 Pa, 92% of tellurium was volatilized and enriched into the condenser from TLAS. Condensate results revealed that 88% of elemental tellurium was directly recovered in the volatile matter. The appropriate gasification-condensation processes realized a clean utilization to extract tellurium and separate multi valuable metals effectively.

After stacking pre-oxidation treatment, lead anode slime was leached in sulfuric acid added with sodium chloride and oxidant of sodium chlorate. The leaching rates of As, Te, Sb, Bi and Cu are more than 98% with potential controlled at 500mV. And noble metals are left in the residue, which are separated from the base metals effectively. Through cooling and crystallizing out arsenate, the solution is reduced with potential controlled. According to reducing slag, the recovery rate of Te is 96.52%. Sb is recovered by neutralizing hydrolysis and the recovery rate is 95.2%. By the effect of iron powder, As, Bi and Cu are entirely reduced with the recovery rates of Bi and Cu to be 91.56% and 83.49%, respectively. The total recovery of As from the crystalline product and reducing slag achieves 91.56%.
