摘　　要：铋碲矿用盐酸加氯酸钠浸出 ,浸出液用Na2 SO3 还原得粗碲粉 ,还原后液水解回收铋。粗碲粉经盐酸浆化洗涤 ,可得纯度达 96 %的碲粉。Bi Te ore is leached with HCl+NaClO 3 .Leached solution is reduced with Na 2SO 3 to obtain rough Te powder. Reduced solution is hydrolyzed to recover Bi. Rough Te powder goes through purification with 2 mol/L HCl to obtain >96% Te powder.
