Abstract The flowsheet to float spodumene in alkaline medium without desliming has long since been borne out by its simplicity, low cost and easy supply of reagents. It was ensured in industrial practice that the spodumene concentrate with a grade of 6.0-6.1% Li_2O and recovery of 88-90% may be produced from ore containing 1.2-1.3% Li_2O. Several trials have been made to troubleshoot for separation of spodumene from the froth together with beryl such as:1050℃ decrepitating-sizing;600℃ roasting-flotation;85℃ digesting-flotation as well as flotation at room tem-perature. Among these the satisfactory results were obtained, and some of them were brought into operation in mills. Especially, the separation of beryl from spod-umene by flotation with“mixed reagent”(FeCl_3+Na_3SiO_3)add edto Na_2CO_3, Na_2S, oxidized paraffin soap at room temperature was a great success. Hence, the flowsheet of cleaning separation and bulk flotation of beryl-spodumene is developed providing a new way for recovery and separation of oughing froth containing these two minerals.
