My invention is a new type of melting unit for the extraction of the metallic magnesium. It can be used in the metallurgical field for the production of magnesium from his native mineral.
Background of Art.
The extraction of the magnesium from his native mineral is produced in two way: thermic and electrolytic. The thermic extraction is produced in special melting unit that works in atmospheric vacuum and with appropriate temperature in such way that the metallic magnesium can distill and then can be condensed in a cold room.
The prior art provided a type discontinuous melting unit for the extraction of the magnesium, in fact it is loaded with the mineral of magnesium and after the magnesium distillation it is unloaded by the residues and reloaded for a new cycle.
The electrolytic extraction of the magnesium is produced in plant that introduce in the environment an elevated pollution
Disclosure of Invention The melting unit, object of my invention, is a continuous extraction melting unit, in fact the mineral is loaded with continuity, the magnesium is drawn out in continuous and the cinders are drawn out in continuous way My invention relates a continuous melting unit with operation under atmospheric vacuum and with a proper temperature for the distillation of the metallic magnesium.
The advantages to use this my special melting unit in alternative to other thermic furnace are the continuity of the process of extraction, while in comparison to the types of process of extraction of the magnesium by electrolytic plant introduces a very smaller environmental pollution.
