Abstract: Lepidolite flotation testwork was performed on 21 variability samples from the EMILI deposit in Allier, France, with head assays ranging from 0.49 to 1.38% Li2O and an average K80 of 236 mm. After desliming, flotation was performed with an amine collector which was able to produce lepidolite concentrates grading >4.2% Li₂O with over 74.6% Lithium recovery from 13 samples - often without cleaner flotation. The lower grade lepidolite concentrates (<4.2% Li2O) were a result of unwanted recovery of other mica-type gangue minerals, as well as low feed grades below the 0.8% Li₂O cut-off grade already excluded from the mine plan.
