The Pilbara Minerals board has granted approval for the company to construct a demonstration plant to produce lithium at Pilgangoora in WA.
The Pilgangoora project is a joint venture (JV) between Pilbara Minerals and Calix Limited. It aims to demonstrate the benefits of producing mid-stream lithium using electric kiln technology.
It is estimated that converting spodumene in this way could cut carbon emissions by 80 per cent.
“Following further studies and pilot test work, we are delighted to be taking the next step in our mid-stream strategy with the construction and operation of a mid-stream demonstration plant with our JV partner Calix,” Pilbara Minerals managing director and chief executive officer Dale Henderson said.
“The mid-stream strategy has potential to materially improve the battery materials supply chain for lithium through reduction in carbon energy intensity, reduction in transport volumes and creating more value at the mine site.
“It has the potential to be a game changer compared to the traditional spodumene to chemicals processing route.”
The estimated construction cost for the project is $104.9 million, which will be partially funded through a $20 million Federal Government grant.
Calix chief executive officer and managing director Phil Hodgson said the company is delighted in the progression of the project.
“Together with Pilbara Minerals, we look forward to demonstrating the potential of our electric calcination technology to dramatically reduce the carbon footprint of Australian lithium,” he said.
“The success of the joint venture will also showcase the opportunity of combining Australian mineral and renewable energy resources with innovative Australian technology to enable the reliable and sustainable supply of value-added critical minerals to the world.”
