Abstract
during alkali electrolytic process of 1 # pure tellurium production, insoluble anode was used in electrolysis , oxygen could be generated in the reaction process and by-products were appeared in the anode. Around 40%tellurium contained in Guixi smelter’s tellurium anode slime, acid leaching reduction process was adopted and tellurium recovery rate was about 90%. Through exploration the experiment, a new recovery technology of tellurium anode slime was found. By using reducing agent A leaching under the conditions of 95℃leaching temperature, 3h leaching time, 5 liquid-solid ratio, 3 times of tellurium metal quantities reducing agent feeding, the recovery rate of valuable metals in tellurium slime could be increased from 90%to 95%above.关键词
