Abstract

Abstract

As a relatively high-energy-consumption and high-pollution industry, the steel industry's energy-saving and emission-reduction pathways are crucial for achieving the goal of sustainable development. The blast furnace slag generated from smelting vanadium-titanium magnetite contains a large amount of titanium components, which are difficult to treat and thus stockpiled in large quantities, causing serious environmental pollution and resource waste. Therefore, the efficient and clean utilization of titanium-containing blast furnace slag and the improvement of valuable component utilization are of great significance to the steel industry. This paper provides a comprehensive review of the enrichment technologies for titanium components in titanium-bearing blast furnace slag, including selective, hydrometallurgical, and pyrometallurgical enrichment processes. It also provides prospects for the electric furnace melting separation–photocatalytic pretreatment–microbial acid leaching method. Currently, the treatment and resource utilization of titanium-bearing blast furnace slag still face numerous challenges, with key priorities including breakthroughs in chlorine removal from chlorination process waste residues, reducing pollution and costs in acid–alkali processes, and promoting the development and application of green and clean technologies to achieve high-value utilization of titanium resources.
