Magnesium | Geoscience Australia
Magnesium metal can be produced by one of three processes: The electrolytic process uses magnesium chloride produced from either magnesite, seawater or brines rich in magnesium chloride. Magnesite is favoured as the source of magnesium because chlorine is recycled within the process rather than being disposed of as a waste or a by-product.
Calcium | Article about calcium by The Free Dictionary
Today, calcium metal is usually prepared by electrolysis of fused calcium chloride to which a little calcium fluoride has been added. It is used in alloys with other metals, such as aluminum, lead, or copper; in preparation of other metals, such as thorium and uranium, by reduction; and (like barium) in the manufacture of vacuum tubes to remove residual gases.
