Yallourn power station inks deal to supply fly ash to LMG

The Yallourn Power Station in the Latrobe Valley

Latrobe Magnesium (LMG) and EnergyAustralia have signed a Memorandum of Understanding (MoU) for Yallourn power station to supply its fly ash to LMG’s proposed magnesium plant in the Latrobe Valley.

The MoU allows for the expansion of the plant from 3000 tonnes per annum to 40,000 tonnes per annum.

Latrobe Magnesium’s project is a world-first in developing a magnesium production plant from brown coal fly ash.

It will use its patented hydromet extraction process and its own newly developed fast cycle vertical retort furnace (FCR).

From January to March 2018, LMG will conduct laboratory scale tests on Yallourn fly ash to determine whether its hydromet process or Monash University’s process are best suited to produce magnesium, saleable iron product and supplementary cementitious material.

Upon the successful completion of this work, LMG will produce a large scale beneficiated sample of Yallourn fly ash to process through its FCR, currently being commissioned at CSIRO in Melbourne.

From the FCR test work LMG will then be in a position to complete a feasibility study using Yallourn fly ash.

Each stage of this project is conditional on the successful completion of the previous stage and the signing of formal agreements between the parties.

“The MoU with EnergyAustralia Yallourn removes one of our last hurdles in developing our Latrobe Valley magnesium plant,” Latrobe Magnesium CEO David Paterson said.

“The results of our FCR test work with CSIRO is where our main focus is now directed.

“We should have the results of our tests on RWE fly ash by the end of February 2018.”
