Research on the trend of lithium and gallium in the selection and metallurgy process of bauxite ore in Mianchi area
The mineral characteristics of lithium and gallium in bauxite ore and bauxite ore are analyzed in Mi-anchi area.The enrichment and trend of lithium and gallium in bauxite ore during the beneficiation process are studied in Mianchi area.By conducting beneficiation and dissolution test on ores from a certain mining ar-ea and adjacent mining areas,the raw ore,concentrate,tailings,and red mud are analyzed.The study result shows that gallium cannot be enriched in the commonly used bauxite flotation process,while lithium can be enriched in the beneficiation tailings,with an enrichment ratio of 1.86-2.57.During the leaching process,more than 80％of lithium and gallium in the raw ore will be enriched in the circulating mother liquor,and their comprehensive recovery and utilization should be carried out in the production process of alumina oxide.
