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

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.
