Research on the Comprehensive Recovery and Utilization Technology of a Tungsten Tailing in Ganzhou,Jiangxi Province
摘要
Abstract
Main mineral composition of a tungsten tailing in Ganzhou,Jiangxi Province is quartz,and the secondary minerals are potash feldspar,plagioclase,lithium muscovite,zinnwaldite,biotite,etc..The grade of Li2O is 0.19％,and lithium is mainly concentrated in mica minerals.In order to determine the development and utilization process of the tungsten tailings,based on their characteristics,a systematic experimental study was conducted to recover lithium mica using desliming flotation,and quartz using magnetic separation flotation for lithium tailings.The remaining products were used as clay raw materials for cement.A lithium mica concentrate with a yield of 10.76％,a Li2O grade of 1.41％,an Rb2O grade of 0.39％,and a Li2O recovery rate of 76.39％was obtained,quartz concentrate with a yield of 64.79％,SiO2 grade of 95.52％,and SiO2 recovery rate of 71.39％The clay raw material used for cement with a yield of 24.45％has achieved good beneficiation technical indicators through experiments,and successfully achieved the full resource utilization of the tungsten tailings,providing technical support for the development and utilization of the tungsten tailings.关键词
