Lithium Australia NL (ASX:LIT) and ANSTO Minerals (AM) have been working together since 2015 on the development of halide accelerated leaching for the extraction of lithium from Li-bearing micas, spodumene and hectorite clays.
This technology has been termed SiLeach®.
The driving force behind development of SiLeach®, initially, was to develop a hydrometallurgical process to extract lithium from micas and spodumene without the need for energy intensive, high temperature processing. This driving force remains today and continues to hold promise in realising the value of previously under-utilised lithium resources.
A comprehensive understanding of the technology and its applicability to the processing of micas and spodumene currently exists, and the flowsheet has been rigorously piloted. Production of battery grade lithium carbonate has been demonstrated.
This publication will provide an overview of the development of the Sileach® technology and associated downstream purification steps.
