卡尔多炉处理铜阳极泥工艺中碲元素的反应机理及分布状态

Reaction mechanism and distribution status of tellurium element in the process of copper anode slime treatment by Kaldo furnace

以铜陵有色稀贵金属分公司铜阳极泥为例,根据铜阳极泥中碲的物相分析,对碲的不同化合物形态在卡尔多炉冶炼工艺条件下的反应机理及分布状态进行分析,为采用卡尔多炉工艺从铜阳极泥回收中碲元素的冶炼操作提供依据。

Basing on the example of copper anode slime in Tongling Nonferrous Rare & Precious Metals Subsidiary Company,according to the phase analysis of tellurium in copper anode slime,the paper analyzes the reaction mechanism and distribution status of tellurium's different compound forms under Kaldo furnace smelting process conditions,and provides a basis for smelting operation to recover tellurium element from copper anode slime using Kaldo furnace process.
