Abstract: In order to make efficient use of a lithium ore resource in West Africa，in view of the fact that the ore contains both lepidolite and spodumene，multiple sets of conditional tests are carried out to de⁃ termine the optimal test parameters.The results show that the lepidolite concentrate with Li2O grade of 2.84% and recovery rate of 30.58% and the spodumene concentrate with Li2O grade of 5.20% and recovery rate of 59.21% are obtained through the whole process closed-circuit test of desliming，mica flotation and spodu⁃ mene flotation. The total Li2O recovery rate is 89.79%，which realizes the efficient recovery of lithium in this resource.

Key words: lepidolite, spodumene, flotation
