Australian mineral exploration and development company Impact Minerals is advancing its Lake Hope High-Purity Alumina (HPA) Project in Western Australia, with a pilot-scale test programme, eyeing around 20kg of 4N high-purity alumina for independent verification and potential customer evaluation. The initiative builds on earlier laboratory research and aims to validate the company’s processing flowsheet as it moves towards commercial-scale development.
Edith Cowan University is constructing a pilot facility in Joondalup under a Cooperative Research Centres Projects (CRC-P) collaboration backed by the Australian Government. The facility would reinforce mineral processing, leaching and related development activities.
Impact Minerals has appointed Simulus Group to oversee testing involving corrosive reagents and hydrogen chloride gas sparging. The work would cover leaching, gas handling, aluminium chloride hexahydrate crystallisation, solid-liquid separation, thermal decomposition and calcination.

Chairman Jim McKerlie described the programme as part of Lake Hope’s “testing phase”.
“We are proving each step of our flowsheet, from the lab through to a pilot plant,” McKerlie stated. He regarded the programme’s phases as “practical and necessary steps that validate the process and deliver the data we need to scale up with confidence.”
Impact Minerals has completed a Prefeasibility Study (PFS) for Lake Hope and is progressing towards a Definitive Feasibility Study (DFS). The pilot programme is aimed at providing further process validation and data to support the project’s development.
The company also holds a 50 per cent stake in Alluminous, which produces HPA at its Perth pilot plant for customer qualification. Its activities span across supplying samples to US-based battery technology group Charge CCCV (C4V).
