Lithium Australia SILEACH test run produces 99% purity

THE BOURSE WHISPERER: Lithium Australia (ASX: LIT) announced the completion of a second continuous pilot plant run by ANSTO Minerals (a division of the Australian Nuclear Science and Technology Organisation).

Lithium Australia said the second continuous pilot plant ran from 10 to 13 October 2016 and was a follow up exercise to the initial process piloted at ANSTO Minerals from 12 to 17 September 2016.

The initial pilot plant run demonstrated the successful application of Lithium Australia’s trademarked Sileach process for the extraction of lithium from lepidolite ore from Lepidolite Hill in Western Australia.

The company explained the second pilot plant campaign processed purified liquor generated in the first campaign and involved evaporation, recovery of lithium carbonate and recovery of potassium sulphate, which is being assessed as a potential value adding by-product.

These steps were previously developed in a laboratory program performed by ANSTO Minerals.

Lithium Australia said the pilot plant operated robustly producing six kilograms of approximately 99 per cent purity lithium carbonate concentrate and provided further engineering design data for the company’s Sileach process.

The lithium carbonate concentrate will be used to produce high purity lithium carbonate and lithium hydroxide products for offtake purposes.

“LIT’s goal is to establish a low cost lithium production profile – similar to the brine producers,” Lithium Australia managing director Adrian Griffin said in the company’s announcement to the Australian Securities Exchange.

“We are very pleased with the results as reported by ANSTO Minerals, Australia’s pre-eminent expert in lithium extraction technology.

“This is another step in de-risking the commercialization of the halogen based Sileach process.”
