Research status and development trends of bioleaching technology
The development and the utilization of low-grade mineral resources constrain global green and sustainable development.Bi-oleaching technology is a cutting-edge technology for achieving green and sustainable development in mineral processing and non-fer-rous metal metallurgy and plays an important role in in-situ remediation of heavy metal pollution sites in mines.This article reviewed the basic concepts,microbial physiological characteristics,and mechanisms of action of biotechnology,as well as the application and re-search status of biotechnology in copper ore extraction,refractory gold ore oxidation pretreatment,uranium ore extraction,and rare earth extraction.In the future,research should be conducted on the selection of high-efficiency leaching microorganisms,the interface mechanism of bioleaching,high-efficiency energy-saving devices,and engineering technologies,and further expanding the application fields of bioleaching technology.
