Abstract: The spodumene ore contains 1.46% Li2O， and the mineral composition is complicated. The main useful minerals are spodumene and gangue minerals are quartz， feldspar and glimmer. The spodumene is closely related to quartz and feldspar. Most of them are polygranular distributed， partly decentralized. It is acicular in mica and quartz， or in the form of flakes， granules， etc.， distributed in mica fissures. It is a complex and refractory pegmatite spodumene ore. In order to determine the development and utilization process of the ore， beneficiation experiment was conducted. The results showed: at the grinding fineness of 72.2% passing 0.074 mm， via magnetic separation （636.94 kA/m） to removal iron and spodumene recovered by flotation process， in which uses Na₂CO₃+NaOH as pH regulator and gangue mineral dispersant， CaCl₂ as activator， and TSY-15 as collector. Through one roughing， two cleaning， three scavenging and middlings bach to the flowsheet in turn process， the spodumene concentrate with Li₂O grade of 6.02%， recovery of 80.65% and Fe₂O₃ content of 0.67% is obtained.

Key words: Pegmatite spodumene ore, Iron removal by magnetic separation, Flotation
