Discussion on development trend and future technology of open-pit mining in our country
Aiming at the problem of low recovery rate in the production process of a spodumene ore in the methyl card area of Sichuan,the results of on-site process inspection were analyzed,and the experimental research was car-ried out in the laboratory.It was determined that the main causes of the above problems were the coarse particle size,unreasonable selection and configuration of flotation machine and other factors.In view of this problem and ac-cording to the actual situation of the lithium concentrator itself,a technical transformation plan for adding five-stack high-frequency vibrating fine screen and screen regrinding system and BF flotation machine transformation and ap-plication was formulated.The technical upgrading of the spodumene mine was carried out without stopping produc-tion as much as possible.It provides reference for subsequent similar mine process transformation.
