Insights into the floatability between spodumene and albite from crystal chemistry standpoint
International Journal of Mining Science and Technology, 2022 Spodumene is a silicate mineral rich in lithium. However, the gangue mineral, albite has similar crystal chemical structure and composition to spodumene. In this work, the density functional theory (DFT) calculation was taken to research the floatability
