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% F e, 1–2% Al, and 1–2% Mg content by applying innovative, economical, environmentally friendly methods. A gitaion 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 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°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°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°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.

Celem badań była ekstrakcja tytanu z nadmorskiego koncentratu magnetytu (Ti-SMC–Ti-doped Seaside Magnetite Concentrated), charakteryzującego się znacznym potencjałem rudy Ti-Fe zawierającej 4–6% Ti, 50–52% F e, 1–2% Al oraz 1–2% Mg, dzięki zastosowaniu innowacyjnych, ekonomicznych i przyjaznych dla środowiska metod ługowania. Ługowanie kwasem solnym HCl z mieszaniem zastosowano do próbek Ti-SMC w różnych temperaturach ługowania (25–50–75–90°C), przy stężeniach kwasu (8–10–12 N) i czasach ługowania (30–60–120–240 min) w warunkach atmosferycznych. Następnie dokonano optymalizacji eksperymentów ługowania z odzyskiem Ti%. Maksymalne wartości odzysku tytanu wystąpiły przy zwiększonym czasie ługowania w temperaturze 50°C i stężeniu kwasu solnego HCl 10 N; 65% Ti odzyskano w ciągu 30 min, 67% – w 60 minut, 74% – w 120 minut, a 82% – w 240 minut. W przypadku Ti-SMC ługowanie prowadzono w temperaturze 50°C i przy stężeniu kwasu 10 N przez 480 minut i otrzymano wartość ekstrakcji 92% Ti. Zgodnie z wynikami ekstrakcji we wszystkich eksperymentach ługowania jako optymalne warunki określono: temperaturę ługowania 50°C, stężenie kwasu 10 N i czas ługowania 480 minut. W pracy podkreślono, że surowiec ten stanowi potencjalną rezerwą, wcześniej niewykorzystywaną. Ekstrakcja 92% Ti z ługowaniem kwasem solnym w warunkach atmosferycznych jest metodą przyjazną dla środowiska, zużywającą mniej energii niż Ti-SMC, która jest trudna i droga do ekstrakcji tradycyjnymi metodami.
