AN APPARATUS FOR THE EXTRACTION OF METALLIC MAGNESIUM

摘要

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.
