从铜铅阳极泥中回收碲的质量控制

THE QUALITY CONTROLLING OF RETRIEVING TELLURIUM FROM A COPPER'AND LEAD'ANODE SLIME

监于精碲所用原料曹达渣的成分近年来发生了较大变化 ,使产品质量发生了波动。为控制精碲质量 ,对影响精碲的关键杂质铅、硒、钠的脱除 ,进行了一些技术上的探讨和攻关 。

In recent years the quality Tellurium was being droped, for the cause of changing in content of soda slag that it is a resource for retrieving Tellurium. Some key injurious ingredient for the fine Tellurium, such as Pb?Se?Na must be remored. A works for the objective have obtained better effects.
