锂辉石调整剂及其作用机理研究进展OA

In the context of the fluctuating international lithium resource market,spodumene,as a high-quality lithium resource,has received high attention from countries around the world.The selection of adjusting agents is cru-cial for achieving efficient separation of spodumene and its vein minerals.This article introduces the crystal structure and surface properties of spodumene and its gangue minerals,summarizes the characteristics and shortcomings of acti-vators and inhibitors,and elucidates the mechanism of action of adjusters.Metal ions have strong activation ability but poor selectivity.Pre assembling metal ions with collectors,small molecule organic agents,or small molecule inorganic inhibitors to improve the selectivity of activators is an important research direction in the future.For the spodumene feldspar quartz system,future efforts should focus on developing highly selective inhibitors suitable for cationic collec-tor systems such as amines;For the spodumene beryl system,the development of highly selective and low toxicity lithium beryllium separation inhibitors that can replace toxic agents such as Na2S is of great significance.
