高温焙烧毒重石的实验研究

Experimental Research on High Temperature Roasting of Witherite

通过对当前钡矿开发利用状况的分析及利用方法的比较 ,确定了采用高温焙烧作为钡矿利用的中间过程。分析了毒重石矿高温分解的机理 ,通过一系列实验对焙烧条件作了较细致的研究 。

The present state of development and utilization of barium mineral resources and the utilization methods are analysed. High temperature roasting is established as the middle process for utilizing barium minerals. Mechanism of high temperature decomposition of witherite is analysed and roasting conditions are investigated by a series of tests, the optimum testing conditions of high temperature roasting of witherite is established.
