Study on Magnesium Metal Preparing by Serpentine Carbon-Thermal Reduction Reaction

Abstract:

Metallic magnesium is prepared with serpentine breeze in vacuum induction furnace by adding calcium fluoride. In the furnace, the vacuum degree should be controlled at 500Pa, while the temperature needs to be heated to 700°C and keep the temperature for 60min in order to dewater the crystal water; And then continue to rise the temperature to 1500°C and keep the temperature for 60min which can deoxidize the element Fe and Ni in the serpentine breeze to metallic iron and metallic nickel, while metallic magnesium become vapor magnesium and then crystal to metallic magnesium at the condenser. Metallic iron and nickel in the furnace slag can be recovered through magnetic concentration and the furnace slag after magnetic concentration can be inverted to silicon carbide through carbothermic method.
