摘　　要：这是一篇工艺矿物学领域的论文。锂是重要的稀有金属,广泛应用于冶金、机械、化工、陶瓷、玻璃建材等工业,成为新型材料的重要部分。此次研究选取了李家沟锂辉石矿采选固废矿物,对其进行系统的工艺矿物学研究,查明固废矿物中主要含锂矿物以锂辉石为主,其次为锂白云母,少量锂云母、铁锂云母、磷锂锰矿、锂电气石等,锂辉石为主要的回收矿物。锂辉石嵌布粒度主要分布在0.04~0.32 mm粒级范围。粗粒级中锂辉石解离度相对较低,不超过80%,总解离度为80.69%。精矿产品中Li_(2)O的理论品位为7.25%,精矿理论回收率为89.69%。This is an article in the field of process mineralogy.Lithium is an important rare metal,which is widely used in metallurgy,machinery,chemical industry,ceramics,glass building materials and other industries,and becomes an important part of new materials.In this study,solid waste minerals extracted from Lijiagou spodumene mine were selected for systematic process mineralogy research.It was found that the main lithium containing minerals in the solid waste minerals were spodumene,followed by lithium muscovite,a small amount of lithium mica,iron spodumene,lithium manganese phosphate,lithium tourmaline,etc.Spodumene was the main recovered minerals.The distribution size of spodumene mainly ranges from 0.04 to 0.32 mm.In the coarse grade,the dissociation degree of spodumene is relatively low,not more than 80%,and the total dissociation degree is 80.69%.The theoretical grade of Li_(2)O in concentrate product is 7.25%,and the theoretical recovery rate of concentrate is 89.69%.
