Infinity Lithium Company Restricted (‘Infinity’, or ‘the Firm’) is happy to announce the completion of its Locked Cycle Take a look at Program (‘LCT’) carried out at Simulus Group laboratories. The LCT program confirmed distinctive lithium recoveries from prior Li-Stream RPKTM course of take a look at work (refer the ASX announcement 7 September 2023) and improved lithium recoveries from the just lately finalised subsequent lock cycle simulations. All LCT take a look at work accomplished at Simulus Group Laboratorieswere led and managed by the Infinity GreenTech Technical Advisory Committee.
- Complete Locked Cycle Take a look at Work (‘LCT’) program accomplished at Simulus Group Laboratories leads to affirmation of remarkable recoveries at San José.
- The LCT confirmed the profitable utilisation of Li-Stream RPK™ with >
90% recoveries of the lithium from Run of Mine to the ultimate finish product. - San José Run-of-Mine ore pattern used to check and optimise Li-Stream
RPKTM in help of engineering research. - LCT confirmed the constant manufacturing of battery grade lithium hydroxide monohydrate from San José lithium bearing mica.
- LCT confirms and exceeds Up to date Scoping Research lithium recoveries assumptions.
- Outcomes present information for future detailed engineering research and optimisations by demonstration plant design.
The finalisation of LCT for Run of Mine (‘ROM’) to finish product by the patent pending Li-Stream RPKTM course of on the San José Lithium Venture (‘San José’, or ‘the Venture’) supportsrecently accomplished engineering research (consult with ASX announcement 9 November 2023 – Up to date Scoping Research), and has supplied information for additional course of optimisation to be included within the subsequent levels of Li-Stream RPKTM course of growth. The Firm is assessing the subsequent steps for an illustration plant for the affirmation of elevated scale of manufacturing at San José.
The take a look at work carried out simulated the entire course of and included recycle streams to evaluate steady-state operation of the mass flows. No main deviations have been discovered from the anticipated regular state circumstances of this course of, confirming accuracy of the method mannequin and additional de-risking the subsequent levels of up-scaled take a look at work.
The outcomes confirmed the suitability of the Li-Stream RPK™ course of at San Josè and the optimum technical possibility for lithium restoration from ROM to finish product.
The take a look at work highlighted the profitable and constant manufacturing of battery grade lithium hydroxide monohydrate utilising Li-Stream RPKTM. The implementation of materially business commonplace onerous rock backend processing methodology (neutralisation, evaporation, crystallisation and last manufacturing of battery grade finish product) and the simplification of unit operations throughout the entire course of (together with the elimination of conventional onerous rock lithium chemical conversion unit operations such because the beneficiation and calcination levels) by the Li-Stream RPKTM course of minimising course of complexity and technical danger.
Infinity’s Chief Technical Officer and Chair of Infinity GreenTech Technical Advisory Committee, Mr Jon Starink mentioned the next relating to the newest outcomes and course of, “This system confirmed the outcomes of course of simulations and validated key parameters underpinning the technical and industrial feasibility of extraction of lithium from the San José materials and supplies a strong basis for additional engineering in the direction of a DFS and the pilot plant design”.
The LCT supplied battery grade merchandise for all cycles with the next desk displaying the overall impurities (< 0.1%) within the pure lithium hydroxide merchandise:
