Electrowinning of titanium from sulfuric acid titanium solutions has been studied at temperatures between 298 and 343 K, sulfuric acid concentrations between 0.5 and 3.0 M and current density between 500 and 700 A/m². Experiments have shown that titanium can be efficiently recovered on the cathode; however, the recovery efficiency is decreased by iron dissolved in the electrolyte. Acid concentrations and higher current densities were found to dissolve the stainless steel anode, thereby increasing the electrolyte iron content. Apparent activation energy has been estimated at 26.8 kJ/mole. The experiments highlighted the relationship between titanium recovery and acid concentration, revealing that as acid concentration increases, the recovery rate initially rises to a maximum and subsequently declines due to increased transport resistance. This intricate behavior can be attributed to the competition between conductance and resistance within the electrolyte, and emphasizes the importance of optimizing operational conditions in the electrowinning process for titanium recovery.
