李家沟锂辉石矿采选固废矿物工艺矿物学及锂的赋存状态
Process Mineralogy of Solid Waste Minerals from Lijiagou Spodumene Mine and Occurrence State of Lithium
摘要
Abstract
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 Li2O in concentrate product is 7.25%,and the theoretical recovery rate of concentrate is 89.69%.关键词
