Selective flotation of muscovite from a material containing muscovite (15.4%), biotite (13%), and siliceous gangue (quartz and feldspar), using a mixed collector system of Na oleate and dodecylamine acetate, is described. Muscovite floats in preference to biotite when the pulp is initially conditioned with oleate followed by amine at basic pH values. The results indicate that a product containing 63% muscovite with a recovery of 93% can be obtained while using 75-150 g oleate and 96 g amine per ton. The biotite grade and recovery are â?0 and 20%, resp. A good selectivity between muscovite and siliceous gangue is obtained. A final product containing 95% muscovite with an overall recovery of 75% is obtained when the flotation concentrate is subjected to magnetic separation Thus, muscovite can be separated from biotite by using a mixture of collectors.
