铍资源回收与高值化工艺进展

Progress on the recovery and value-increment of resources containing beryllium

铍是一种具有优异性能的轻金属,在核能、惯性导航系统和红外光学系统等领域发挥重要作用。由于我国铍资源匮乏,回收铍生产、应用过程中大量产生且未被充分利用的铍二次资源就显得尤为重要。同时,随着我国电子、航空航天等行业的迅猛发展与高端器件的不断迭代,对金属铍的纯度也提出了更高的要求。为实现铍资源高值化利用,推动高纯铍制备工艺的自主研发,围绕工业生产及应用过程中含铍资源的回收工艺以及高纯铍的精炼进行系统性综述,并针对各工艺优势和不足进行分析和展望。

Beryllium,a light metal with excellent properties,plays an important role in nuclear energy,inertial navigation system,infrared optical system and other fields.Due to the scarcity of beryllium resources in China,it is particularly important to recycle and utilize the secondary resources of beryllium which are produced in large quantities and not fully utilized in the process of beryllium production and application.At the same time,with the rapid development of China′s electronics,aerospace and other industries and the continuous iteration of high-end devices,higher requirements have been put forward for the purity of metal beryllium.Therefore,in order to realize the high-value utilization of beryllium resources and promote the independent research and development of high-purity beryllium preparation process,this article systematically reviewed the recovery methods and process flow of beryllium-containing resources and the refining process of high-purity beryllium products in the process of industrial production and application.This article also analyzed and prospected the advantages and disadvantages of each process mentioned above.
