云南省锗资源现状及开发利用对策研究

Study on the Present Situation and the Exploitation Countermeasure of Germanium Resource in Yunnan

介绍了锗资源的特性与锗的主要用途,综述了云南省铅锌矿含锗和褐煤含锗资源的分布及特点,分析了从含锗铅锌矿和含锗褐煤中提取锗的工艺现状以及锗常规产品和精、深产品加工现状,指出了目前云南省锗资源开发利用存在的主要问题:资源利用率低、环境污染严重、精深产品少、锗产品附加值低以及对锗作为一种战略物质的认识不足。对开发利用云南省丰富的锗资源,从多个方面提出了建议。

This paper introduces the characteristic and the main application of germanium resource, summarizes the distribution and peculiarity of germanium contained in lead-zinc ore and lignite, analyzes the progress of distilling germanium in lead-zinc ore and lignite, and the machining status of common goods and refined goods of germaniurn. It also points out several problems of germanium resource in exploitation and utilization; the utilizing rate being low, environmental pollution being serious, refined goods being absent, additional value being low and looking germanium as a strategic material being impercipient, and so on. This paper advances many proposals to exploit and utilize the rich germanium resource in Yunnan from several aspects.
