Mineralogical characterization and flotation tests were carried out for the lithium-bearing mica in a granitic pegmatite-type lithium ore from Xinjiang. It is found that lithium-bearing mica is similar to gangue minerals of albite and quartz in terms of surface properties, and also presents close mineral dissemination characteristics. On this basis, a self-developed high-selectivity collector GYMR was adopted in a closed-circuit flotation process, consisting of one stage of roughing, two cleaning and two scavenging, to achieve efficient separation of lithium-bearing mica with grinding fineness of-0.074 mm 75.20%. Finally, a lithium-bearing mica concentrate grading Li2O 2.65% at 15.22% recovery was obtained from the closed-circuit flotation test. It is confirmed that the GYMR collector has remarkable advantages in selective adsorption of fine-grained lepidolite and gangue minerals.
