A demonstration (DEMO) fusion reactor will require a huge amount of beryllium (Be) with approximately 490 tons. Since the total production of Be in the world, for now, is approximately 300 tons per year, it is anticipated that the demand is dramatically increased as the early realization of the fusion reactor proceeds. The presence of many Be mines, as well as information on each Be reserve, has already been confirmed with surveys. Since a conventional Be refinement process is considerably complicated including a production process for an intermediate product, Be(OH)₂, high-temperature treatments, and handling of toxic powdery states, however, Be raw materials are costly. To provide a steady supply of Be for DEMO, in parallel with the development of mines, a novel Be refinement technique using an economical and safe process is imperative. According to these requirements, a novel and advanced refinement process of Be metal from ores was suggested by applying microwave melting at low temperatures through wet processing.

It was obvious as a result of dissolubility tests that bertrandite and beryl ores were completely dissolved by using a process with acid solutions and microwave heating after treatment with base solutions and microwave heating. Further, the process can be utilized to produce not only intermediate products, such as beryllium hydroxide (Be(OH)₂) and beryllium oxide (BeO) but also pure beryllium metal. Moreover, this process has great advantages for extracting uranium which is one of critical issues and oxide impurities for reuse.

一个示范（DEMO）聚变反应堆将需要约490吨的大量铍（Be）。由于目前世界上Be的总产量约为每年300吨，因此随着聚变反应堆的早期实现，预计需求将急剧增加。调查已经确认了许多Be矿的存在以及每个Be储备的信息。由于常规的Be精制工艺非常复杂，包括中间产品Be（OH）₂的生产工艺，高温处理和处理有毒粉末状态，但Be原料价格昂贵。为了与矿山开发同时提供稳定的Be用于演示的Be精炼技术，采用经济，安全的工艺精制Be精制技术势在必行。根据这些要求，提出了一种通过湿法在低温下进行微波熔化的新颖，先进的从矿石中提炼Be金属的工艺。

溶解性试验的结果表明，在用碱溶液和微波加热处理之后，通过使用酸溶液和微波加热的方法，将膨润土和绿柱石矿石完全溶解。此外，该方法不仅可以用于生产中间产物，例如氢氧化铍（Be（OH）₂）和氧化铍（BeO），而且可以生产纯铍金属。此外，该方法对于提取作为关键问题之一的铀和氧化物杂质可重复使用具有很大的优势。
