altech

Australian innovator Altech Chemicals Ltd. announced yesterday that it has finalized the design for its high-purity alumina (HPA) plant that is soon to be built in Johor, Malaysia.

Per the company’s press release, the site’s design is the product of data collected during a recent geotechnical survey and consultations among EPC contractor SMS group GmbH, permitting consultant WKL & Associates, and local government representatives.

Altech’s layout of the site includes seven buildings – three for production and the remainder for various supporting functions. The process will begin in Building 1 with kaolin beneficiation, filtration, and meta-kaolin conversion, then proceed to Building 2 for kaolin leach, leach residue, and waste water neutralization circuits, then on to crystallization, roasting, calcination, and HPA finishing in Building 3.

Iggy Tan, Altech’s managing director, greeted the news as the accomplishment of an important milestone on the journey to bring HPA to the wider global market.

“The HPA plant site layout and building designs are of the highest calibre. Naturally, the designs are to international standard and of a quality expected from our appointed German EPC contractor SMS group. The next step of project development is application for a development order from local authorities. We are currently waiting for a land sub-title number (PTD number) to be issued for the ~4HA site, so that the development order can be submitted. Once the development order is issued, the staged mobilisation of various sub-contractors, most of which are Johor based, will commence.”

Altech Chemicals is based in Subiaco, Western Australia and is attempting to implement a marketable process for delivering 99.99% (4N) HPA using conventional equipment at a lower production cost than methods currently available. It plans to construct a 4,500 metric ton per annum HPA plant at Tanjung Langsat Industrial Complex, Johor, Malaysia that will use kaolin clay from a company-owned mine in Meckering, Western Australia. The firm is fast-tracking HPA production due to an agreement with Mitsubishi for 100% of its proposed HPA production for ten years. At present, Altech intends to commence project development later this year.
