Extraction of titanium from Ti-doped seaside magnetite concentrate in HC1 media

The purpose of the present study was to extract high added value titanium from Ti-doped Seaside Magnetite Concentrated (Ti-SMC), which has a high potential reserve for Ti-Fe with 4-6% Ti, 50-52% Fe, 1-2% Al, and 1-2% Mg content by applying innovative, economical, environmentally friendly methods. Agitaion HCl leaching was applied to the Ti-SMC sample at different leaching temperatures (25-50-75-90 degrees C), at acid concentrations (8-10-12 N), and leaching times (30-60- -120-240 min) in atmospheric conditions. After the leaching experiments under the indicated conditions, the optimization of the leaching experiments was determined with Ti% recovery that dissoluted by elemental analysis, and the titanium recovery values reached the maximum value with increased leaching time at 50 degrees C and 10 N HCl acid concentration; and 65% Ti was recovered in 30 minutes, 67% in 60 minutes, 74% in 120 minutes, and 82% Ti in 240 minutes. For Ti-SMC, leaching was carried out at 50 degrees C leaching temperature and at 10 N acid concentration for 480 minutes, and a 92% Ti extraction value was achieved. According to the extraction results of all leaching experiments, the leaching temperature of 50 degrees C, the acid concentration of 10 N, and the leaching time of 480 minutes were determined as the optimum conditions. In this study, it was emphasized that this resource is a potential reserve, which has not been used as a source before, with 92% Ti extraction with atmospheric acid leaching, which is an environmentally friendly method, consuming less energy than Ti-SMC, which is difficult and expensive to extract with traditional methods.
