HPA First

The HPA First Process is the application of the Company’s proprietary licenced solvent extraction and refining technology to produce HPA from an industrial feedstock.


HPA First was adopted in July 2018 as a major advance on the previous process flowsheet, which used a feedstock generated from the acid-leaching of laterite mineralisation from the Collerina Ni-Co-Sc Project, in central NSW.

The HPA First Project Definitive Feasibility Study (DFS) has now been delivered (March 2020) with a compelling business case, capable of delivering 10,000tpa of 4N (99.99% purity) High-Purity Alumina (HPA) into the burgeoning HPA market.  Financial Highlights include:


The HPA First Project utilises a novel, proprietary licenced process flow sheet  based on Solvent extraction (SX) to deliver a disruptive and highly competitive entry into the HPA Market.
