Recovery of Titanium from Blast Furnace Slag Industrial ...

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 ...

Three electric furnace methods for producing high-carbon ...

For acid slag operation, the furnace temperature is about 1320-1400 ℃ lower than that of the flux method. The production of this method requires not only qualified high-carbon ferromanganese, but also low-phosphorus, low Iron-rich manganese slag. The solvent-free smelting process of high-carbon ferromanganese is continuous.
