LPI Produces Battery Grade Lithium Carbonate With 99.92% Purity From Maricunga Project
HIGHLIGHTS
- Optimisations introduced to the production process of LPI’s Maricunga lithium project exceed industry standards, with 99.92% purity battery grade lithium carbonate being produced from samples of concentrated brine.
- Technical certification by IBZ-Salzchemie GmbH & Co, under international standards, was conducted under the supervision of GEA Messo in Germany and LPI’s experts in Chile.
- Samples will now be sent to potential lithium buyers for analysis as part of LPI’s financing plans for mine construction at Maricunga.
SYDNEY, Australia, Nov. 17, 2022 (GLOBE NEWSWIRE) -- Lithium Power International Limited (ASX: LPI) (“LPI” or the “Company”) is pleased to provide the results from the latest optimisations introduced to the Maricunga lithium production process in January 2022 in the project’s updated Definitive Feasibility Study.
Lithium Carbonate with a 99.92%1 purity was produced from original, concentrated brine from LPI’s test evaporations ponds at Maricunga. This significantly exceeds the industry standard specifications for battery grade lithium carbonate of 99.5%.
A relevant test to measure the Loss of Ignition (“LOI”) was also conducted for 30 minutes at 500 °C, showing an LOI of 0.2%. As a result, the purity after LOI was 99.72%.
As announced in the March 2022 Quarterly Report released to ASX on 29 April 2022, concentrated brine had been sent to LPI’s technological partner GEA Messo to further test production processes.

1 Purity after Loss of Ignition – LOI for 30 minutes at 500 °C – of 99.72%.
This work was executed by the independent certified laboratory, IBZ-Salzchemie GmbH & Co KG in Germany. This was done under the supervision of GEA, with the objective of producing up to 10kg of battery grade Li2CO3.
The chemical analysis and detailed composition of impurities was as follows:
