Recovery of Titanium from Blast Furnace Slag

17.01.2013  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

the slag has to be higher than the metal smelting point, because metal is heated up by using slag liquid phase. The optimum smelting point has been practically noted between 1680-1720 °C. The composition of ferro-chrome slag in the phase diagram is shown in Figure 3. The proportion of quartzite in the charge mix controls the right slag composition. The slag composition is tested every day by sampling and
