Abstract

The continuous thermal extraction melting unit is composed by a charging hopper (1) that is equipped of system of hydraulic closing (2). The native mineral, through the duct (3), reaches the cochlea of feeding (4) so to be fed in the distillation zone (5). Same equipments of heating are placed on the side walls (6), they provide necessary heat for distillation. The exhausted mineral returns back through the concentric duct (7) to the run of feeding. It reaches the closing exit valve (8) to be unloaded. A extractor crusher (9) provide to facilitate the exhausted mineral extraction. The vapours of magnesium through the duct (10) reach the walls of the condenser (11), fed with cold fluid (12), to condense as metallic magnesium. A scrapper (13) handles to scrape the dust from the walls and to carry it out through the closing exit valve (14). A vacuum pump through the connection (15) allows the extraction of the incondensable gases.

Description

Description
AN APPARATUS FOR THE EXTRACTION OF METALLIC MAGNESIUM
Technical field.
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.

Claims

Claims
1. A melting unit built in vertical way, in which the native mineral is introduced in coaxial way to the duct of extraction of the exhausted mineral (part 4 fig.l)
2. The melting unit of claim 1 is characterized by the extraction run of the exhausted mineral that achieves in countercurrent to the introduction run of the native mineral (part 7 fig.l) .
3. The melting unit is provided with extractor crusher of extraction of the exhausted mineral (part 9 fig.l) .
4. The melting unit is provided with a harvest and carriage duct of the magnesium vapours to the condenser (part 10 fig .1 ) .
5. The melting unit is provided with a condenser of the magnesium vapours (part 11 fig.l).
6. The melting unit of claim 1 or 2 is provided with a system of heating set inside in the zone of distillation (part 6 fig.l) .
7. The melting unit of claim 6 is provided with a system of heating set outside in the zone of distillation (part fig .6 1 ) .
8. The melting unit is provided with the connection (part 14 fig.l) . through which a vacuum pump allows the extraction of the incondensable gases.
