Lepidico has Successful Lithium Pilot Plant Campaign

Lepidico has achieved 99.9 per cent purity high-specification lithium carbonate at a L-Max pilot plant campaign in Perth, Western Australia.
Other than calcium, impurity levels of most harmful elements for battery-grade specifications were below detection limits, according to Lepidico.
The company believes elevated calcium levels are due to contamination in reagents used during final precipitation stages. Test works are in progress to improve lithium chemical purity.
Other existing producers have a nominal battery-grade reference purity of 99.5 per cent.
The back end of the pilot plant will be converted to LOH-Max capability to produce lithium hydroxide.
Major mechanical equipment is on-site with reagents trialled and sourced. The first batch trial is expected in November this year.
Lepidico recently completed a merger with Desert Lion Energy to launch a lithium project in Namibia.
The company holds an 80 per cent interest in the Karibib lithium project, which covers approximately 1000 square kilometres.
Lepidico is focussed on exploration, development, and production of lithium chemicals, owning technology to metallurgical processes to produce lithium carbonate from non-conventional sources.
