Infinity Lithium Corporation Ltd (ASX:INF) has noted that its pre-feasibility study (PFS) work on its San Jose Lithium Project in Spain continues to confirm positive assumptions from the scoping study.
Following successful plant stage I and II test work, plant stage III test work has now provided further confirmation of the recycling and successful reuse of potassium sulphate in the roasting and water leach process.
Potassium sulphate is a key reagent required in the roasting process to extract the lithium product.
The ability to recirculate potassium sulphate has the obvious benefit of lowering operating costs and final test are being completed.
Infinity expects ultimately a 90-100% recycling rate to be achieved, requiring minimal ‘fresh’ potassium or sodium sulphate ‘top up’ through the production cycle.
The finalisation of capital and operating costs can now occur, enabling Infinity to move forward towards completion and release of the PFS.
