我国铍矿资源概况及选矿技术研究现状

General Situation of Beryllium Ore Resources and Research Status of Mineral Processing Technology in China

我国铍矿资源主要集中在新疆、内蒙古、四川、云南,主要为花岗伟晶岩型、气成-热液脉状型2种类型,以伴生资源为主,铍消费大量依赖进口,加强国内铍资源选矿及综合利用技术攻关,实现其高效、合理开发,是保障铍资源安全的重要举措。本文介绍了我国铍矿资源概况、类型、分布、开发利用、选矿工艺及药剂使用的现状,阐述了铍矿选别过程中的核心问题及解决方法,提出新型高效浮选药剂研发是提高铍矿选别指标的技术关键,同时,鉴于我国铍矿品位低、共伴生有价组分多的实际,指出资源梯级综合利用是铍矿选矿发展的重要方向。

Beryllium resources in China are concentrated in Xinjiang, Inner Mongolia, Sichuan and Yunnan,mainly including two types: granite pegmatite and aerogenetic hydrothermal vein. Associated beryllium resources are the majority, while beryllium consumption depends heavily on imports. Thus, strengthening the technical research on beneficiation and comprehensive utilization of domestic beryllium resources,realizing its efficient and reasonable development are significant measures to ensure the safety of those resources. This paper introduces the current situation of domestic beryllium resources, including general situation, types, distribution, development and utilization, mineral processing technology and reagents,expounds the core problems and solutions in the process of beryllium ore beneficiation, and puts forward that the research on new high-efficiency flotation reagents is the technical key to improve the beneficiation index of beryllium ore. Simultaneously, in view of the reality of low grade and multiple coassociated valuable components of beryllium ore in China, it is pointed out that the cascade comprehensive utilization of resources is an important direction for the development of beryllium ore beneficiation.
