我国对鈹矿的普查与勘探,是最近几年才开始的。普查和勘探的对象是含绿柱石的伟晶岩矿床。这种绿柱石颗粒较大,可以手选,也可以土法开采。经过几年的摸索,伟晶岩脉含这种矿产并不丰富,远远不能满足需要,因此必需寻找新矿床类型。如果比较一下世界的伟晶岩型及气成热液型绿柱石矿床的规模及综合利用的条件,可以看出气成热液类型是值得引起我们重视的矿床类型。两类矿床的品位和规模,如下表所示:
China’s beryllium survey and exploration in recent years only began. The object of the census and exploration is the pegmatite-hosted pegmatite deposit. This beryl larger, can hand-selected, can also be mining. After several years of exploration, the pegmatite contains this mineral is not rich, far from meeting the needs, it is necessary to find a new type of deposit. If we compare the size of the pegmatite and gas-forming hydrothermal-type beryl deposits in the world and the conditions for their comprehensive utilization, we can see that the type of gas-forming hydrothermal fluids is a type of deposit that deserves our attention. The grade and size of the two types of deposits are shown in the following table:
