Lithium Australia NL (ASX:LIT) has exceeded quality specifications for the production of lithium carbonate from material processed using its wholly owned Sileach™ halogen digestion process.
A comparison of carbonate quality achieved from the Sileach™ tests and published is as follows:
Refined Lithium Carbonate Assay
(ppm, unless otherwise stated)
|Battery Grade Specification (FMC Lithium)|
Production of high-quality carbonate demonstrates the ability to produce commercial products from a range of silicate materials, some of which are not commonly processed to produce lithium chemicals, due to limitations in existing processing routes.
This outstanding result is a significant prelude to continuous Sileach™ pilot plant operations on spodumene concentrates from Pilbara Minerals’ (ASX:PLS) Pilgangoora project. The pilot plant at ANSTO is being prepared for processing the concentrates towards the end of January. Lithium Australia is confident that the run will create a benchmark in the hydrometallurgical processing of spodumene, potentially heralding a paradigm shift in lithium processing practices.
Managing Director, Adrian Griffin Said:“The production of such pure lithium carbonate, puts Lithium Australia’s Sileach™ process in the hydrometallurgical limelight. We have demonstrated the ability to process complex lithium ores, without the requirement of the traditional and expensive roasting step. We anticipate generating similar ground-breaking results with the production of lithium carbonate from Pilbara Minerals’ Pilgangoora spodumene concentrates, later this month.”
