Construction has now been completed on the lithium Mid-Stream Demonstration Plant, developed through a joint venture between Calix and PLS (formerly Pilbara Minerals) at the Pilgangoora Operation in Western Australia.
The completion of construction of Calix’s first electric plant at commercial scale marks an important milestone for the Calix Group.
In demonstrating a novel approach to add value to critical mineral exports and decarbonise the most carbon-intensive step in battery making, the Mid-Stream Plant is designed to test and validate the application of Calix’s platform technology to lithium processing, providing critical learnings for potential future scale up and deployment.
Beyond lithium, the Mid-Stream Demonstration Plant is an important proof point for Calix’s core platform technology. By successfully applying electric calcination at commercial scale, the project aims to demonstrate the broader potential of the platform to electrify metals and minerals processing across multiple industries. This includes applications in iron and steel, cement and lime, alumina, carbon removal, and other critical minerals, where high-temperature processing is conventionally both energy and emissions-intensive.
Following construction completion, the joint venture will provide updates on commissioning and operating plans in due course.
