In a process for producing titanium metal by electrolysis of a titanium halide in a cell containing fused alkali or alkaline earth metal halide salt, the cathode of said cell being provided with a perforated surface facing the anode and separating the fused electrolyte into an anolyte and a catholyte, TiCl4 is introduced into said catholyte for a predetermined time during which the ratio of electric current to TiCl4 feed is greater than 9 faradays/mole of TiCl4 and thereafter gradually adjusting the feed rate of the TiCl4 and/or the current passed through the cell to provide a current to TiC14 feed ratio of from 4.5 to 7 faradays per mole of TiCl4. During the predetermined initial period the average current to feed rate ratio may be 20 - 40 faradays/mole, and during the latter part of said period the TiCl4 feed may be discontinued. Towards the end of the electrolytic operation the feed rate may be reduced resulting in an increase of current to feed rate ratio to 9 - 14 faradays/mole.
