Latrobe Magnesium - turning residual ash into useful magnesium metal

The Environment and Local Community

LMG is committed to World’s Best Environmental Standards for its magnesium facility in Victoria’sLatrobe Valley.


The LMG site at 320 Tramway Road has ready access to local infrastructure facilities and the appropriate heavy industrial zoning suitable for smelter use.


LMG’s initial plant will directly employ 38 people and 12 contractors.  The expanded plant will directly employ 203 people and 94 contractors.  It is estimated that during the two construction phases, the company will employ up to 75 and 240 people indirectly.

Air Emissions

Most magnesium plants use a magnesium carbonate feedstock. LMG uses fly ash as feed that contains the magnesium in the mineral oxide form. As a result, minimal carbon dioxide is produced during processing.   Carbon dioxide is also consumed in LMG’s hydromet process.

Hazard Risk Management

LMG will use World’s Best Practice for health and hazard risk management.

Noise Abatement

There is no mining associated with the LMG project.  The plant contains a ball mill which will operate well within World Health Organisation (WHO) minimal noise requirements. Most of the consumables in the process are soft materials and do not require any significant grinding,

Risks to Flora and Fauna

The LMG project will rehabilitate fly ash pond areas. This will improve the landscape and the visual appeal of the area.

Waste Management

LMG ’s process is estimated to remove up to 95% of the fly ash produced by a power station. Residual solids from production process are inert and can be deposited in an industrial waste dump.


Water received in the fly ash slurry from power plants will be recycled back to the power stations for reuse in ash slurrying. Excess water recovered in the plant operation will be cooled and discarded through the existing SWOP line. It is anticipated that there will be no other off site discharges of water from the facility.

Impact on Infrastructure

The fly ash will be slurried to the initial plant.  The product will be initially transported by truck and then transported by rail once the plant is expanded. The increased rail transport should assist the community in developing a regional freight hub at Morwell.

Power and water supply will be local and mostly direct from the existing power generators.

Employment of local personnel to operate the plant should increase the local retail consumption.

The Green Metal

Magnesium is referred to as the “green” metal. Magnesium boasts light weight and high strength characteristics, which are increasingly sought after in the automobile and other industries. Magnesium alloys enable car manufacturers to produce lighter vehicles thus achieving greater environmental sustainability. Lighter vehicles equal greater fuel efficiency, resulting in better utilisation of diminishing oil reserves and lower carbon emissions.
