The electrowinning of chromium metal follows the dissolution of chromium from chromite or high-carbon ferrochrome after its separation from gangue and metallic impurities. Although ferrochrome was found to be the most expensive starting material, the use of chromite ore is not practical because of the number of processing steps involved. Production of electrolytic chromium for Turkey becomes important because of having large reserves of chromite ores and producing an important amount of ferrochromium in the world. It is also one of the most important strategic and critical materials for nations. In the frame of electrolytic chromium production from domestic resources, laboratory-scale chromium electrolysis was conducted using a diaphragm-type cell.
