Abstract

Abstract

In order to realize the efficient comprehensive recovery of lithium, tantalum and feldspar minerals from granite pegmatite type spodumene deposit in Yichun of Jiangxi, the comprehensive recovery test of beneficiation was carried out. The results showed that the combined collector composed of high selectivity reagent ZH and oxidized paraffin soap could realize the effective separation of spodumene with silicate gangue minerals and reduce the influence of fine mud on the mineral surface. Under the condition that the raw ore containing 1.51% Li₂O and 0.022% Ta₂O₅, the comprehensive separation process was as follows: the combined collectors oxidized paraffin soap +ZH were used to flotation spodumene; the tantalum in flotation tailing was recovered by gravity separation process of shaker; and the feldspar was recovered by the separation process of low intensity magnetic separation-high intensity magnetic separation. The process could be obtained spodumene concentrate containing 5.62% of Li₂O and recovery rate of 74.65%, tantalum concentrate containing 18.78% of Ta₂O₅ and recovery rate of 40.21%, feldspar concentrate with yield of 49.16%, Na₂O 2.45%, K₂O 4.60%, TFe 0.15% and whiteness of 62.9%. The beneficiation test index of the process was good, which realized the comprehensive recovery of lithium, tantalum and feldspar from hard rock spodumene ore.
