    magnesium metal. Keeping this and the past experience of the laboratory in extraction of magnesium by the Pidgeon process in view, a new attempt has been made to extract magnesium by an alternate process. Magnesium metal has been produced in a vaccum resistance melting furnace of 200 kVA, at slag temperature of 1650°C.
