Kwinana produces first lithium hydroxide

Commissioning of the first production train at Kwinana has progressed at pace over recent months with the commissioning programme designed to hot commission each of the individual unit processes sequentially from calcining, acid roasting, leaching, purification and crystallisation on a batch basis, culminating in the production of the first lithium hydroxide chemical.

With first lithium hydroxide production now demonstrated, the focus will turn to operating Train 1 on a continuous, rather than batch basis, while also progressively improving product quality to a battery grade product for qualification by its offtake customers.

It is expected that saleable product will be produced in the December 2021 quarter and that battery grade product for accreditation by customers will be produced in the March 2022 quarter.

Train 1 is expected to then progressively ramp up to the design production rate of 24 000 t/y lithium hydroxide by the end of 2022.

“First production of lithium hydroxide is the first step of a journey but nevertheless represents a key milestone for the joint venture (JV). We are therefore delighted to have achieved this first important step in the commissioning of Train 1 and to have done so ahead of the internal schedule developed earlier this year,” said IGO MD and CEO Peter Bradford.

“We congratulate the Kwinana team on this milestone and their progress over the last few months.

“The strong demand being witnessed in the lithium market globally reinforces the strategic nature of Kwinana which, together with the JV’s interest in the Greenbushes mine, is rapidly evolving into a globally significant, integrated lithium operation catering to the specific needs of premium lithium-ion battery manufacturers”.

IGO holds a 49% interest in Kwinana through the incorporated lithium JV it formed with Tianqi Lithium Corporation at the end of June this year. Through the JV, IGO also holds a 25% indirect interest in the Greenbushes mine.
