The basic data for the deep resource utilization technology of high-titanium-bearing blast furnace slag are generated from laboratory and pilot-scale production experimental studies. The data were obtained by analyzing the phase compositions of slag, titanium-extraction tailings and refined tailings via X-ray diffraction (XRD), and investigating the occurrence states of vanadium and titanium in the reduced titanium-bearing phases, titanium-extraction tailings and refined tailings using scanning electron microscopy (SEM), Mineral Liberation Analyzer (MLA) and energy-dispersive X-ray spectroscopy (EDS). Studies were conducted on the selective carbonization kinetics of blast furnace slag, foaming behavior of molten slag, precipitation and growth law of TiC, selective chlorination kinetics and regulation mechanism of carbonized slag, sticking and flow loss mechanism during chlorination, multiphase interaction rules in the reactor, dechlorination of refined tailings and vanadium product preparation technology, phase precipitation behavior and reconstruction mechanism of titanium-extraction tailings, and chlorine diffusion behavior. The kinetic characteristics of carbonization and chlorination reactions are elucidated, the carbonization reaction pathway and heterogeneous chlorination reaction mechanism are clarified, and the crystallization behavior of titanium-extraction tailings and the law of chloride ion diffusion are revealed. This work lays a solid theoretical foundation for the deep resource utilization of high-titanium-bearing blast furnace slag.
