Traditional magnesium smelting

Sodium, magnesium and aluminum are active metals and should be smelted by electrolysis.

Attachment: Scope of application of the four methods:

Thermal reduction method: moderately active metals, such as iron and copper.

Electrolysis: active metals, such as sodium magnesium aluminum, etc.

Aluminothermic reaction method: melting high melting point metals, such as tungsten.

Thermal decomposition method: inert metal, such as mercury.
