Recovery and recycling of lithium: A review - ScienceDirect

2017-1-1  Recovery of lithium from ore/clay by bioleaching. The spodumene (LiO 2 Al 2 O 3 4SiO 2), is a potential recourse for Li but it is considered as a very resistive mineral in the industry for industrial lithium recovery. The mineral beneficiation of spodumene and lithium extraction from spodumene is high energy intensive process.
