Alpha makes strides in constructing the HPA circuit

Alpha HPA is getting closer to fully starting up their high purity alumina (HPA) circuit at their Stage 1 precursor production facility in Queensland.

The company has reported that they are in the final stages of using a A$15.5-million grant from the Critical Minerals Development Programme. This grant will help them set up a small-scale commercial HPA circuit within the Stage 1 project.

The HPA circuit will increase PPF production capacity for aluminium nitrate and aluminium sulfate, producing up to 15 tonnes per year of extra HPA, 15 to 25 tonnes per year of HPA trihydrate, and an additional 10 tonnes per year of high purity boehmite. It will also enable nano HPA production for semiconductor users and the creation of HPA tablets for synthetic sapphire glass growth.

Furthermore, the Queensland government is investing up to A$30 million in Alpha HPA to help transform locally-produced alumina into the glass for smartwatches and phones. This investment will allow Alpha HPA to create specialized furnaces for sapphire glass production, enabling them to produce more than 4 tonnes of sapphire glass each year.

Before the new HPA circuit is up and running, the Stage 1 precursor production facility already produces high purity alumina to support sales and product test orders. They also supply aluminium nitrate to the Brisbane facility to fulfil test orders for other high purity materials.
