Li hydroxide produced at Paradox project in Utah

Perth-based lithium developer Anson Resources has produced lithium hydroxide at its Paradox lithium brine project in the US state of Utah.

The lithium hydroxide was produced from research and development precipitation test work using brine from the project's Cane Creek area. It utilised a production process developed by Lilac Solutions to extract lithium from brine using an absorption method. Lithium carbonate has already been produced from the Paradox project's brines.

Lilac is aiming to produce battery grade products from the project's brines, and further testing is underway to produce larger samples.

Engineering consultancy Hatch has been appointed to coordinate test work leading up to a pre-feasibility study on the project in 2019.

"The company is moving as quickly as possible to determine the most economical process to recover value from Paradox brines. The ability to produce either lithium carbonate or lithium hydroxide would enable the company to meet the demands of customers of both products and would provide the flexibility to meet changes in product demand," managing director Bruce Nicholson said.
