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 Pre-Feasibility Study (PFS) has now been delivered (Nov 2018) with a compelling business case, capable of delivering 10,200tpa of 4N (99.99% purity) High-Purity Alumina (HPA) into the burgeoning HPA market.  Financial Highlights include:
