摘要
含钛高炉渣可直接用于制作混凝土、渣棉和混凝土砌块等原材料,但其钒、钛有价资源得不到有效利用。中国含钛高炉渣储量大,且每年仍以较快速度增长。因而含钛高炉渣钛资源提取问题成为研究热点。通过对含钛高炉渣钛提取技术的相关研究进行回顾,分别从钛铁合金、钛白和四氯化钛等不同富集形式,对含钛高炉渣钛提取工艺的过程以及优缺点进行综述,并分析探讨各工艺可行性,期望可以促进钛资源可持续健康发展,达到资源综合利用目的。
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.
