Altech Announces Promising Results for the Feasibility Study of an Alumina Coating Plant in Germany


Australian innovator Altech Chemicals Ltd. this week released promising results from its Preliminary Feasibility Study (PFS) of a 10,000 metric ton per year silicon/graphite alumina coating plant in Saxony, Germany, predicting a 40% yield rate for the project.

According to the company, the plant, which would produce Silumina Anodes proprietary high-capacity silicon/graphite battery anode materials, would involve an initial investment of US$95 million. The projected net present value of the plant would be US$507 million, generating US$63 million per year when in operation.

Altech’s PFS projects a 40% internal rate of return on the project, recouping its entire capital investment in just over three years. Upon reaching design capacity, the PFS found an annual revenue at the site of US$185 million.

General Manager Iggy Tan said in a statement on the Australian Stock Exchange that the PFS revealed a very lucrative opportunity for the company.

“While Altech’s top priority continues to fund its Johor HPA project, the Silumina Anodes project represents an exciting downstream opportunity to utilize its HPA coating technology in silicon/graphite battery materials. We are delighted and excited with the results of the PFS of 10,000 tpy of silumina anodes. Due to the attractive economics of the study, AIG’s Board of Directors decided to proceed immediately to a Definitive Feasibility Study (DFS) for the project. AIG has already purchased land in Germany suitable for the project, and the AIG team in Saxony is expected to begin DFS work immediately. We believe that the production of Silumina Anodes materials could be a breakthrough technology for the lithium-ion battery industry.

Altech has already identified sources of graphite and silicone feedstocks for the plant at SGL Carbon GmbH (SGL) and Ferroglobe Innovation SL (Ferroglobe). With environmental accreditation from the Norwegian Center for International Climate and Environmental Research (CICERO), Altech has begun construction of a pilot project adjacent to the site of the proposed alumina coating plant that will provide samples to potential customers for testing.

Altech Chemicals is based in Subiaco, Western Australia and is attempting to implement a commercializable process to deliver 99.99% (4N) HPA using conventional equipment at a lower production cost than alternative methods. currently available. It plans to build a 4,500 metric ton per year HPA plant at the Tanjung Langsat Industrial Complex in Johor, Malaysia, which will use kaolin clay from a company-owned mine in Meckering, Western Australia. . The company is accelerating HPA production due to an agreement with Mitsubishi for 100% of its proposed HPA production for ten years.
