Research Progress of Microbial Technology in Utilization of Rare Earth Resources
Rare earths are non-renewable and valuable resources that are widely used in production and life.In view of the current situation of extensive rare earth mining and lack of effective recovery of rare earth,the ad-vantages of microbial technology in leaching rare earth from low-grade tailings and recovering rare earth from waste are focused,and the research on microbial leaching of rare earth and related mechanisms are emphatical-ly introduced,mainly including microbial leaching,recovery,enrichment and purification of rare earth.The main defects of microbial leaching of rare earth are briefly described.The research direction and challenges of microbial leaching technology in rare earth field are prospected based on the existing research achievements.
