Abstract: Described herein is a method for the recovery of two major valuable lithium minerals (amblygonite and spodumene), a cesium mineral (pollucite) and quartz. The method comprises a series of direct flotation processes combined with reverse flotation processes that were designed to recover these lithium and cesium concentrates.
