PERTH – Lithium miner Pilbara Minerals has announced a final investment decision on the mid-stream demonstration plant at the Pilgangoora operation.
The estimated construction cost of A$104.9-million will be partially funded with a A$20-million grant from the Australian government, with Pilbara Minerals funding A$67.4-million of the remaining budgeted construction expenditure, while Calix will pay the remaining A$17.5-million. “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,” said Pilbara MD and CEO“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.
The assessments conclude that successful implementation of electric calcination on-site at a spodumene mine and concentrator could materially reduce carbon emissions intensity associated with spodumene calcination by more than 3 kg carbon dioxide equivalent per kilogramme LiOHᐧHO when using renewable energy compared to using coal as the thermal energy source in rotary kiln calcination.
