Magnesium resources, reserves and production Metalpedia

Resources of dolomite and magnesium bearing evaporite minerals are enormous. Magnesium bearing brines are estimated to constitute a resource in the billions of tons, and magnesium can be recovered from seawater at many places along the world's coastlines. However, magnesium reserves are highly concentrated in three countries Russia, China and Korea.

The Electrolysis of Magnesium

Seeing as though magnesium is one of the most abundant element upon land and in water, making up 13% of the Earths mass and mantle, magnesium is primarily extracted from seawater and magnesium rich salt brines, and it therefore seems highly improbable that Australias natural magnesium reserves will deplete in the foreseeable future.
