ABSTRACT:
A Process for the electrolytic production of metals particularly titanium and alloys starting from the corresponding compounds is disclosed, by means of an apparatus for the electrochemical extraction including: (1) a cathode-crucible containing a mass of solidified metal, a liquid electrolyte with a density which is lower than that of the metal and a pool of liquid metal produced; (2) one or more non-consumable anodes particularly immersed in the electrolyte with means for regulating their distance from the cathodic surface; (3) a feeding system to the electrolyte of the compounds of the metals, of the electrolyte constituents and of alloying materials; (4) a power supply which feeds direct current to the liquid metal, and through the electrolyte, to the anodes, and causes the cathodic reduction of the metal in liquid form and the evolution of anodic gas, with the heat generation which maintains the electrolyte in the molten state; and (5) an air-tight containment structure in which the anodic gases generated during the electrolysis are collected.
