铍柱石

The Nanping granitic pegmatite is one of the most important rare-metal deposits in China. In this pegmatite field the No. 31 granitic pegmatite is the most highly evolved and well mineralized one, where beryl is the most important beryllium mineral.

福建南平花岗伟晶岩是中国重要的稀有金属花岗伟晶岩之一，其中31号脉是分异程度最高、稀有金属成矿作用最重要的岩脉，绿柱石是其中最主要的铍矿物。

It does not occur uncombined in nature but is found chiefly as the mineral beryl (of which emerald and aquamarine are gemstone varieties).

自然界不存在单质铍，主要存在于矿物绿柱石(其中祖母绿和海蓝宝石都是宝石型变种)中。

This paper describes the process for producing commercial beryllium oxide from non-beryl beryllium ore,especially the method for producing commercial beryllium oxide from high-fluorine beryllium ore and presents production situation of Shuikoushan commercial beryllium oxide.

叙述了非绿柱石铍矿生产工业氧化铍的工艺，特别是高氟铍矿生产工业氧化铍的方法，介绍了水口山工业氧化铍的生产状况。
