Strategic Metallurgy, in association with Lepidico, has developed a hydrometallurgical process to extract and recover battery grade lithium carbonate from lithium containing mica.
Lithium bearing micas such as lepidolite and zinnwaldite have largely been overlooked until the advent of L-Max® as a source of lithium as no commercially viable process existed to recover this metal, which is essential for many new battery technologies.
Flowsheet development – Lepidolite flotation
Flowsheet development – L-Max®
Miniplant construction and operation- 140h continuous operation
to produce lithium carbonate with a purity >99.5% at 94% recovery from
the leach liquor.
Feasibility study- 91.3% lithium recovery to a >99.5% lithium carbonate concentrate
