Experimental Study on Improvement of Tellurium Recovery from Lead Anode Slime AITranslate
Abstract AITranslate
Tellurium was recovered from lead anode slime after pre-oxidation treatment,leaching and reduction precipitation.The results show that optimized recovery processes of tellurium are as follows：natural stacking oxidation treatment-leaching in the system of sulfuric acid,sodium chloride and sodium chloratepotential controlled precipitation of tellurium with sodium sulfite.Leaching rate of tellurium is 92.15% after the lead anode slime is treated by natural stacking oxidation for 4d,and then leached in the solution system of 3 mol/L sulfuric acid,3 mol/L sodium chloride and 20% sodium chlorate under the following conditions：liquid to solid ratio of 5∶1,reaction temperature of 80℃,reaction time of 4hand stirring leaching.More than 90%copper and other valuable metals are leached,while silver and lead remain in the residue.The process of potential controlled precipitation of tellurium with sodium sulfite was conducted in leaching solution,and the reduction rate of tellurium reaches 92.57% by controlling the potential at 0.342～0.568 Vand adding 2times theoretical amount of sodium sulfite as the reducer.Copper and other valuable metals remain in the solution to be recovered in the next step.Tellurium comprehensive recovery rate can be up to 85% by using the above optimized process to recover tellurium from lead anode slime to coarse tellurium slag.
