Pigeon Process Advantages• Capital Cost <$500 /tonne annual production v Electrolytic Capital

Cost $10,000/tonne annual production

• Retorts can be added progressively - incremental expansion of

production

• Dolomite is an abundant source material

• Process has high tolerances suitable for developing nation.

• Plants are small and mobile can follow cheap energy

Disadvantages• Labour intensive

• Batch Process individual retorts typically produce < 200 kgms/batch

• Dolomite source material 20% MgO v’s 40% MgO in Magnesite

• Consumes 1.08 tonnes of FeSi/tonne of Mg.

• Plants are currently polluters.

• China’s dominance of production is a concern to consumers.

A New Paradigm For Leigh Creek Magnesite

Previous work has focused on Magnesium Metal

Magnesia (Mg0) market has expaned• Refractories supplying the Steel Industry

• Expansion into building Products (MgO)• Board – binder for bricks• Chemical applications – lateritic Ni/Co

Magnesia Market Advantages• Lower capital cost• Broad range of consumers• Magnesia is a bigger market
