High titanium slag (HTS) is a famous byproduct for its high content of TiO 2 (15 % ∼ 27 %) generated from the production of pig iron by smelting vanadium titano-magnetite [12]. Approximately 80 million tons of HTS have been produced in the Panzhihua Iron and Steel Plant (China) during the past several decades.
