AMMG produces 99.99 per cent (4N) purity alumina

THE BOURSE WHISPERER: Australia Minerals and Mining Group (ASX: AKA) has produced 99.99 per cent (4N) high purity alumina (HPA) using the company’s own innovative aluminous clay (kaolin) to HPA processing technology.

AMMG filed three patent applications for its processing technology in February 2013 when it announced it had achieved production of greater than 99.9 per cent (3N) HPA.

At this time AMMG lodged three patent applications to protect the intellectual property of its processing technology.

The company has now produced the 4N HPA by utilising its unique processing technology in collaboration with its consulting processing chemists, TSW Analytical, which was engaged in mid-2012 to refine and verify AMMG’s process and produce HPA material.
“After producing greater than 99.9 per cent HPA, we conducted additional trials to subsequently achieve the 4N HPA,” AMMG managing director Ric Dawson said in the company’s announcement to the Australian Securities Exchange.

“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.

“This successful result confirms the capacity of our processing technology and gives us the confidence to pursue the interest we have received from potential investors and off-take customers.

“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.”

AMMG’s 100 per cent-owned South West HPA project carries a combined JORC resource of 297 million tonnes of aluminous clay.

The company claims this to be the second largest currently reported aluminous clay deposit in the world.
