Kaolin alumina: Altech gains construction approval for kaolin-HPA project

Roskill view: Australian- based, Altech Chemicals Ltd, is pushing ahead with plans to produce high purity alumina (HPA) from its kaolin deposit at Meckering, Western Australia. Altech is planning to mine and screen kaolin, before transporting it via the port of Freemantle, to Johor, Malaysia where the company proposes to construct an HPA plant.

The company has just been granted approval for construction of a kaolin screening and loading facility adjacent to its run-of-mine stockpile at its Meckering deposit, which is approximately 140km east of Perth. The facility will screen to a size of <12mm, which will then be conveyed into a housed container loading facility before transportation by road to Freemantle.

The end goal for Altech is to produce HPA, which is used in synthetic sapphire production, which in turn are used in high value applications such as substrates for LED lights, scratch resistant glass in smartphones, and semi-conductor wafers used in the electronics industry. Altech has completed a BFS for the construction and operation of a 4ktpy HPA plant and is currently in the process of securing project financing with aim of starting project development in 2018. The company will be the first to be producing HPA from kaolin commercially, as other suppliers in the sector use aluminium metal as a feedstock.

Roskill’s new Kaolin: Global Industry, Markets & Outlook report will be published in September 2017.
