Australia Minerals & Mining Group seeks patent for alumina processing technology

Australia Minerals & Mining Group has filed a new patent application with the Australian Patent Office for its unique acid-based alumina processing technology.
The technology produces alumina from its aluminous clay material with purity levels greater than 99.95% purity.
It also benefits from a low energy input as the process uses low temperatures and pressures while its key reagents are recyclable.
High purity aluminium is used in a number of applications such as high-performance electronics; tablets, mobile phones, computer screen backlighting; LED’s; and hybrid cars.
It ranges in price from US$141,000 and US$396,000 per tonne depending on the purity and particle size.
Australia Minerals & Mining Group’s aluminous clay material from its licence in Australia’s southwest is a low impurity feedstock and has relatively high alumina levels.
The Yilgarn Craton, which hosts the company’s aluminous clay projects, is one of the oldest weathered cratons on earth.
The weathered granites have left the residual aluminous clay so that the deposits are ‘primary’ or ‘in situ’ in nature, as opposed to those that are secondary in nature where the aluminous clay has been transported by water and then deposited in typically smaller and narrower deposits or lenses at the bottom of ancient lakes and rivers.
Australia Minerals & Mining Group has delineated two separate aluminous clay resources on its Meckering and Kerrigan aluminous clay projects, totalling 150 million tonnes with screened grades of up to 38% alumina, and an exploration target ranging from 1.3 billion to 1.7 billion tonnes.
Kerrigan currently hosts an Inferred Resource of 85 million tonnes while Meckering has an Indicated Resource of 16.77Mt and an Inferred Resource of 48.28Mt.
The next phase of exploration in order to increase this resource is currently being planned.
