Nov 02, 2013· If only magnesium were less expensive. According to researchers at the Pacific Northwest National Laboratory (PNNL), based in Washington State, USA, the magnesium used in the production of lightweight alloys for cars and aeroplanes is seven times more costly than the steel employed in the same applications.
SMRI views solution mining as mining of underground, watersoluble minerals, usually using one or more drilled wells to dissolve the minerals with water (not by using acids used in metal ore leaching). Minerals such as salt, potash, trona, and magnesium salts may be produced by pumping saturated fluid from underground caverns.
