Infinity Lithium Corporation Ltd (ASX:INF) (FRA:3PM) is making strong progress with test-work as part of the EIT InnoEnergy funded program to produce battery-grade lithium hydroxide from the San José Lithium Project in Spain.
The test-work program funded by EIT InnoEnergy is undertaken and managed by industry-leader Dorfner Anzaplan in Germany and the company’s Technical Advisory Committee in Australia with results generally consistent with pre-feasibility study (PFS) assumptions.
EIT InnoEnergy is part of a platform funded by the European Battery Alliance (EBA) with which Infinity is working closely.
Foundation for feasibility study
This work is intended to provide the foundation for a feasibility study for battery-grade lithium hydroxide production from San José.
The test-work program is based on the PFS delivered in 2019 and is intended to confirm study process assumptions and better define process engineering design criteria.
Lab-scale feasibility level test-work has now progressed to the fourth stage (crystallisation) after progressing through roast, leach and solution purification stages.
Larger-scale of 10s of kilograms feasibility level test-work kicked off in the first quarter of 2021 and has progressed to provide sufficient flotation concentrate to undertake upscaled roasting test-work.
Lab-scale production targeted for Q4
Test-work is on time and on schedule and consistent with the schedules previously advised, with first lab-scale production of lithium hydroxide expected no later than the beginning of Q4 2021.
As well as providing engineering design information, this program is significant in the context of the recently announced MoU for the delivery of battery-grade lithium hydroxide to LG Energy Solutions (LGES) of Korea.
