AMMG produces 99.99% high purity alumina

Australia Minerals and Mining Group Limited is pleased to announce that it has successfully produced 99.99% (4N) HPA (high purity alumina) using its own innovative aluminous clay (kaolin) to HPA processing technology. AMMG filed three patent applications for the aforementioned processing technology in February 2013. The Company previously announced the production of >99.9% (3N) HPA and subsequent to these results, additional trials were conducted to achieve the 4N purity.

AMMG produced the 4N HPA from its unique processing technology in collaboration with its consulting processing chemists, TSW Analytical Pty Ltd. TSW Analytical was engaged in mid-2012 to refine and verify AMMG’s process and produce HPA material using that process.

Mr Ric Dawson, AMMG’s managing director, said “After producing >99.9% HPA, we conducted additional trials to subsequently achieve the 4N HPA. We are now confident from TSW’s work that we will be able to produce higher 5N or 6N purity levels, subject to further successful development of the process."

“We are now reviewing the next steps to progress this project and are scoping the design, construction and financing options for a HPA production plant”, Mr Dawson concluded.

The Company lodged three patent applications in February 2013 to protect the intellectual property of its processing technology. AMMG’s process is favoured by the unique mineralogy of its aluminous clay material, which contains extremely low levels of impurities, such as iron and titanium.

Reported worldwide production of high purity alumina is estimated at 15,000tpa, which is expected to increase at 7% CAGR, predominantly driven by the rising LED market.
