Ti metal and its alloys presents excellent mechanical properties and high corrosion resistance. Although Ti element is abundant in nature as oxides compounds, the cost for metal production prevents its larger use. A recent electrochemical process to produce metal from oxides have been developed, the FFC (Fray-Farthing-Chen) process. In this process, electrochemical reactions reduce the metals oxides cathodes through oxygen ionization and further elimination on anode. In this paper, the use of natural rutile sand to produce low-purity Ti metal by the FFC process was studied. X-ray diffraction, scanning electronic microscopy and energy-dispersive X-ray were used to characterize samples subjected to different process conditions. Ti metal was successfully produced, and the reduction pathway was described. Process parameters were studied to optimize the process, and non-pelletized rutile sand was subjected to reduction, improving reaction rate. Mathematical modelling was performed to study kinetic of experiments parameters.
