锌精矿生产高纯氯化锌新方法

Preparation of Zinc Chloride with Marmatite and Calcium Chloride

介绍了利用锌精矿制备高纯度氯化锌的理论探索和新的工艺条件研究。该工艺采用无水氯化钙和锌精矿为原料经高温下的复分解反应和气化分离可得到高纯度氯化锌。

A new method about the preparation of Zinc Chloride of high purity from marmatite and calcium chloride is introduced. It utilizes the evaporative capacity of Zinc Chloride under lower temperature about 750℃ hence, with this high purity of zinc chloride can be obtained.
