An innovative process for magnesium production
The Magnola process produces magnesium metal using serpentine tailings as the raw material source. These mining residues, containing up to 24% by wt Mg, have accumulated over decades of mining the serpentine ore for asbestos fibres. The tailings are leached with HCl, then neutralised to separate the Si/Fe leach cake residue.
