摘　　要：对从碲渣中提取二氧化碲的过程进行了试验研究,通过浸出、中和及二次沉淀等方法制取二氧化碲。结果表明,采用适当的浸出温度、时间和溶液的pH值,可得到纯度大于99%的二氧化碲。In this Tellurium dioxide paper, the process of extracting tellurium dioxide from tellurium slag is is extracted by leaching, neutralization and secondary precipitation. With pH value of the leaching solution, as well as a proper leaching temperature and time, studied. a proper tellurium dioxide with more than 99% purity can be obtained.
