ABSTRACT: Titanium is one of the most valuable elements found in blast furnace slag, with a concentration of approximate 2.7%. Because of the low level of titanium in slag, the best method of extraction is hydrometallurgy. In this study, parameters such as slag particle size, temperature, concentration of acid, solid-to-liquid ratio, and ultrasonic wave time were used to determine the recovery of titanium. Parameters such as time and stirring speed were kept constant. To examine the results, a two-level fractional factorial experimental design was used. Particle sizes in the ranges of 2.35−3.36 and
