Tenova Technology - Magnesium Oxide (MgO) Production Plant

Tenova, developer and provider of sustainable solutions for the green transition of the metals industry, was awarded a contract by Australian based Latrobe Magnesium Limited (LMG). The scope of the contract includes the engineering, supply, and supervision of the Magnesium Oxide (MgO) production plant at Latrobe Valley, Victoria, Australia, a demonstration plant using a world-first process of combined hydromet / thermal reduction.

In the first phase of the project, Tenova will supply a magnesium oxide (MgO) plant, with spray roaster technology, and an initial capacity of 1,000 tonnes of magnesium (Mg) metal per year. In the second stage, LMG intends to develop a commercial scale operation with an envisaged production capacity in the range of 10,000 to 40,000 tons per annum of magnesium metal.

Using the companys patented hydrometallurgical extraction and thermal reduction process, the plant will harvest magnesium metal from a fly ash resource – with the company stating that it will convert nearly 100% of the resource into valuable commodities, with released CO2 emissions that are approximately 50% less than comparable magnesium production plants. Thereby placing the project at the forefront of environmental sustainability.

“Demand for magnesium worldwide is strong,” said David Paterson, Chief Executive Officer at LMG. “It has the best strength-to-weight ratio of all common structural metals and is increasingly used in the manufacture of car parts, laptop computers, mobile phones and power tools. Currently, the Latrobe Valley contains 25 million tons inventory of fly ash, that is why it so important for us to have a reliable partner in this project”.

“Through many years of experience and continuous improvement of pyro hydrolysis process, Tenova is able to meet specific customer requirements. The positive and constructive cooperation with Latrobe during the development phase of the magnesium production facility was a decisive factor to now deepen this work in the course of realization.”, stated Gregor Kappacher, Branch Manager at Tenova Austria, the competence center for spray roaster technology. “The project is of paramount importance for Tenova, because it opens positive future perspectives and is in line with our effort towards achieving a sustainable industry”.

The first magnesium is forecasted to be produced in 2023.
