摘要：

In order to recover the tellurium and bismuth resources within the Dashuigou tellurium deposit in Sichuan province, China, the leaching of these metals from the raw ore in H2SO4 and FeCl3 media was investigated in this work. The effect of H2SO4 concentration, Fe3+ concentration, liquid/solid ratio, leaching time and leaching temperature was studied. It was found that 99.17% of Te and 92.82% of Bi were extracted into leaching solution under the optimum conditions: H2SO4 concentration of 150 g/L, Fe3+ concentration of 60 g/L, liquid/solid ratio of 6 ml/g, leaching time of 60 min and leaching temperature of 90 degrees C. Furthermore, the sulfur element in raw ore was reduced into elementary substance. There is no production of H2S, which is a positive indicator for environmental considerations.
