Australia's Alpha HPA has broken ground on the second phase of what is planned to be the world's largest single-site ultra-high-purity alumina refinery.

Located on a 10-hectare site in Gladstone, Australia, the project will utilize proprietary licensed solvent extraction and refining technology to produce alumina products with purity levels as high as 99.99% in commercial quantities, supplying critical raw materials for global industries such as lithium batteries, LED lighting, and semiconductor manufacturing.

It is reported that the second phase will build upon the established first-phase operations. The company's initial facilities, already housed in a smaller building at the site, have been producing a range of high-purity alumina and aluminum products on a scaled basis.
