Latrobe Magnesium Limited announced that it has been granted a patent for India for its unique hydromet process. The process involves the treatment of the spent fly ash from brown coal-powered electricity generation using chemicals to reduce sulphur, iron and silicon to acceptable levels so that the beneficiated material can be used as a feedstock in the thermal reduction process. The result is an efficient and novel means of producing magnesium and supplementary cementitious material production extracted from voluminous tailings of industrial fly ash from some of the world's brown coal electricity generators. The process is100% owned by LMG.
