Magnesium Ores and Mines

Magnesite

Being an abundant element of the hydrosphere and biosphere, Magnesium is found as ores in large deposits of Magnesite (Magnesium Carbonate), Dolomite (Calcium Magnesium Carbonate), and Brucite (Magnesium Hydroxide), yet most commonly found dissolved as a  solution in seawater and natural brines.

Magnesite and Magnesium in solution  can be found in deposits and lakes throughout Australia, including the Kunwarara deposit, north-west of Rockhampton in Queensland (Magnesite) ; Thuddungra, northwest of Young in New South Wales (Magnesite) ; and Lake Cargellico and Cobar in New South Wales (Magnesium in solution).
