APPARATUS FOR DEEP PURIFICATION OF METALS Russian patent published in 2022 - IPC C22B9/04 C22B9/02 C01B19/02 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, in particular, to apparatus ensuring the operation of technology for deep purification of non-ferrous metals, wherein the temperature of the technological processes does not exceed 1,250°C. Apparatus comprises a vertically positioned reactor with fittings for purifying metals by metallurgical methods, connected tightly with the flange providing connection to the gas and vacuum lines, as well as a furnace unit placed on top of the reactor and configured to enable changes in the temperature settings and creation of a temperature gradient along the vertical axis of the apparatus. The order of assembly of the reactor is therein the reverse of the purification process and includes a receiving crucible, a condenser, a second distillation funnel mounted thereon, a rack of the distillation part, a second distillation crucible, a first distillation funnel, a flask of the distillation part, and a first distillation crucible and a loading crucible placed inside said flask, wherein said components are placed inside the reactor flask from bottom to top in the order of assembly.

EFFECT: creation of reproducible reliable technologically simple equipment ensuring the production of non-ferrous metals with a purity of 99.99995% wt.
