Abstract:Titanium-bearing blast furnace slag can be directly used to make raw materials such as concrete, slag wool and concrete blocks, but its valuable vanadium and titanium resources cannot be effectively utilized. China's titanium-bearing blast furnace slag reserves are large and still growing at a rapid rate every year. Therefore, the extraction of titanium resources from titanium-bearing blast furnace slag has become a research hotspot. Based on the review of the relevant research on the extraction technology of titanium from blast furnace slag, the process, advantages and disadvantages of the extraction technology of titanium from blast furnace slag from different enrichment forms such as ferrotitanium alloy, titanium dioxide and titanium tetrachloride are summarized, and the feasibility of each process is analyzed and discussed, hoping to promote the sustainable and healthy development of titanium resources and achieve the purpose of comprehensive utilization of resources.
