Tianqi and IGO herald battery-grade lithium milestone at Kwinana refinery

Tianqi Lithium Energy Australia Pty Ltd (TLEA) has announced first production of battery-grade lithium from its plant in Kwinana, Western Australia, marking the first time battery-grade lithium, or lithium hydroxide monohydrate (LHM), has been produced in Australia in commercial quantities.

This is a significant milestone for TLEA and Australian mining as the sector expands to meet rapidly growing demand for rechargeable batteries, primarily from the electric vehicle and energy storage system industries, TLEA, a joint venture between IGO (49%) and Tianqi Lithium (51%), says.

TLEA’s Kwinana plant has successfully met internal certification processes with the on-site laboratory confirming that battery-grade specification has been met on 10 t of lithium hydroxide, produced consistently over several days. Samples have been sent for independent verification, TLEA says.

The next step in the plant’s ramp-up process is customer qualification, which will be completed over the next four to eight months. During this time, the plant will continue to focus on stable, consistent and reliable production of battery-grade lithium.

“We are immensely proud to demonstrate that Australia can value add to its minerals onshore as it enhances its reputation as a critical contributor to the production of batteries for electric vehicles and energy storage, which are absolutely vital for the decarbonisation of the world’s economy,” TLK Chief Operating Officer, Raj Surendran, said.

“This is an exciting time for our shareholders, suppliers and service providers who have contributed to the construction and ramp-up of the Kwinana Plant, and our employees who have worked so hard to turn the dream of producing battery-grade lithium hydroxide in Australia into a reality.

“Today’s milestone proves Australia has the capability and expertise to transition from a ‘dig it and ship it’ minerals supplier to a downstream supplier of value-added product.

“However, we also remain acutely aware that there is more work to do to establish the Kwinana plant as a reliable, significant producer of battery-grade lithium, starting with customer acceptance.”

TLEA owns the first lithium hydroxide plant in Australia and the largest in the world to be built and operated outside of China. Lithium hydroxide produced at the plant will be containerised and exported from the Port of Fremantle to customers around the globe.

Surendran said the first train at TLEA’s Kwinana Plant will now continue its ramp-up towards its nameplate capacity of 24,000 t/y of battery grade lithium hydroxide.

Lithium hydroxide is a lithium-based compound derived from spodumene, a lithium-bearing pegmatite mineral. Spodumene is sourced directly from the Greenbushes mine 250 km southwest of Kwinana (Albemarle 50%, Tianqi Corporation 25%, IGO Ltd 25%).
