A carbothermal process for obtaining magnesium — developed by CSIRO (www.csiro.au) Light Metals Flagship (South Clayton, Victoria, Australia) — overcomes previous limitations to commercial viability. For several years, magnesium has been produced mainly by electrolytic routes, from magnesium chloride sources such as seawater and natural brines. More recently, world production has been mainly in...
