Abstract

The future word-wide production of magnesium metal is projected to increase substantially over the next decade and beyond, basically as a response to the perceived requirement to reduce fossil fuel consumption with a simultaneous reduction in the generation of greenhouse gases. Bittern is considered as a hazard liquid waste to environment, causes massive environmental problems; but it also has many uses in industry and agriculture, as well as being used for production of magnesium and other chemicals. Technology processes combining both were proposed to recover pure magnesium oxide from bittern by precipitation techniques using solution of sodium, or ammonium hydroxide, or oxalic acid. The production of magnesium metal is technically challenging, as well as having relatively high production costs. There are recent methods of producing magnesium metal from oxides involve high temperature reduction, and electrolysis of molten magnesium chloride and other applying laser with solar energy.
