In addition to spodumene, mica, feldspar and quartz were major by-products. A simplified flowsheet for spodumene flotation is shown in Fig. 9. The ore with head grade of 1.64% Li 2 O is milled to −16 mm by ball mill grinding to increase degree of liberation. About 400 g/t of NaOH is added for spodumene surface cleaning during ball …
