Infinity Lithium Company Restricted (‘Infinity’, or ‘the Firm’) is happy to announce the completion of its Locked Cycle Check Program (‘LCT’) carried out at Simulus Group laboratories. The LCT program confirmed distinctive lithium recoveries from prior Li-Stream RPKTM course of check work (refer the ASX announcement 7 September 2023) and improved lithium recoveries from the just lately finalised subsequent lock cycle simulations. All LCT check work accomplished at Simulus Group Laboratorieswere led and managed by the Infinity GreenTech Technical Advisory Committee.
- Complete Locked Cycle Check Work (‘LCT’) program accomplished at Simulus Group Laboratories leads to affirmation of outstanding 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 knowledge for future detailed engineering research and optimisations via demonstration plant design.
The finalisation of LCT for Run of Mine (‘ROM’) to finish product via the patent pending Li-Stream RPKTM course of on the San José Lithium Mission (‘San José’, or ‘the Mission’) supportsrecently accomplished engineering research (confer with ASX announcement 9 November 2023 – Up to date Scoping Research), and has offered knowledge for additional course of optimisation to be included within the subsequent levels of Li-Stream RPKTM course of growth. The Firm is assessing the following steps for an indication plant for the affirmation of elevated scale of manufacturing at San José.
The check work carried out simulated the whole 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 situations of this course of, confirming accuracy of the method mannequin and additional de-risking the following levels of up-scaled check 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 check work highlighted the profitable and constant manufacturing of battery grade lithium hydroxide monohydrate utilising Li-Stream RPKTM. The implementation of materially trade customary arduous rock backend processing methodology (neutralisation, evaporation, crystallisation and remaining manufacturing of battery grade finish product) and the simplification of unit operations throughout the whole course of (together with the removing of conventional arduous rock lithium chemical conversion unit operations such because the beneficiation and calcination levels) via the Li-Stream RPKTM course of minimising course of complexity and technical threat.
Infinity’s Chief Technical Officer and Chair of Infinity GreenTech Technical Advisory Committee, Mr Jon Starink mentioned the next concerning 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 gives a stable basis for additional engineering in direction of a DFS and the pilot plant design”.
The LCT offered battery grade merchandise for all cycles with the next desk displaying the whole impurities (< 0.1%) within the pure lithium hydroxide merchandise:
