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

Abstract

The purpose of the present study was to extract high added value titanium from Ti-doped Seasi - de 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°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 con - ditions, the optimization of the leaching experiments was determined with Ti% recovery that dis - soluted by elemental analysis, and the titanium recovery values reached the maximum value with increased leaching time at 50°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, le - aching was carried out at 50°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 expe - riments, the leaching temperature of 50°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.
