Core produces battery-grade lithium hydroxide from Finniss


Advanced lithium developer Core Lithium has produced battery-grade lithium hydroxide monohydrate (LH) from spodumene mineral concentrate from the Finniss Lithium Project, located just south of Darwin Port in the Northern Territory,

According to the company’s statement, the scoping level test work program demonstrated that the conventional ‘direct’ flowsheet can be applied to the processing of the mineral concentrate sample to produce battery grade lithium hydroxide monohydrate.

Core, whose Finniss Lithium Project was recently granted Major Projects status, said it was now considering the project’s ‘obvious down-stream value potential’ to meet the demands of the ever-increasing lithium battery (LIB), electric vehicle (EV) and renewable energy markets.

Core Lithium Managing Director Stephen Biggins said the test work program confirmed that battery grade lithium hydroxide suitable for high-end uses in the LIB, renewable energy and EV industries, can be produced from excellent quality lithium concentrate produced from the Finniss Project.


“This successful proof-of-concept test work provides Core, and our customers, the confidence in utilising Finniss lithium concentrates in the global lithium battery supply chain,” Mr Biggins said.

“Together with the recent award of Major Project Status from the Federal Government, this program lays a foundation for Core to explore the potential of adding downstream processing infrastructure to our portfolio, incorporating the strong synergies with the infrastructure at the nearby Middle-Arm Industrial Precinct at Darwin Port and aligning with Australia’s national Modern Manufacturing Strategy and expansion of the Global lithium battery supply chain.”
