Lepidico secures US patent protection for proprietary lithium recovery process

Lepidico Ltd. received patent protection in the U.S. for its proprietary lithium chemicals recovery method, known as L-Max, which extracts lithium and certain byproducts from mica minerals to produce lithium carbonate.

The Australia-listed company said Oct. 24 that its national and regional phase patent applications for the process, for which it submitted an international patent application in 2015, are well advanced in other key jurisdictions.

In May, Lepidico signed a nonbinding memorandum of understanding with Abu Dhabi-based Gulf Fluor LLC for the supply of sulfuric acid, the provision of land to build a phase-one plant project in the Industrial City of Abu Dhabi, and for marketing phase-one plant byproducts within the region.
