  • 本研究采用了一种节能路线处理含钛高炉渣，即低温硫酸固化，低浓度硫酸溶液浸出的方法同时提取钛、铝、镁。系统地研究了硫酸固化–浸出含钛高炉渣的工艺参数，在最佳条件下钛、铝、镁的回收率分别达到85.96%、81.17%、93.82%。采用快速浸出模型，限制硅的溶解和聚合，硅的溶出率仅3.18%。研究了硫酸固化-浸出的机理。在硫酸固化过程中反应快速发生并急剧放热，在氢离子的进攻下，渣的结构被破坏，硅酸盐解聚形成可滤性二氧化硅，钛、铝、镁、钙离子被置换形成硫酸盐包裹在无定型二氧化硅颗粒表面。浸出液中钛、铝、镁得到回收，浸出残渣中富集硫酸钙和二氧化硅。该方法有效避免浸出过程硅溶胶的形成，固液分离得到加速。

    Recovery of titanium, aluminum, magnesium and separating silicon from titanium-bearing blast furnace slag by sulfuric acid curing–leaching

      Abstract
    • An energy-efficient route was adopted to treat titanium-bearing blast furnace slag (TBBFS) in this study. Titanium, aluminum, and magnesium were simultaneously extracted and silicon was separated by low temperature sulfuric acid curing and low concentration sulfuric acid leaching. The process parameters of sulfuric acid curing TBBFS were systematically studied. Under the optimal conditions, the recovery of titanium, aluminum, and magnesium reached 85.96%, 81.17%, and 93.82%, respectively. The rapid leaching model was used to limit the dissolution and polymerization of silicon, and the dissolution of silicon was only 3.18%. The mechanism of sulfuric acid curing–leaching was investigated. During the curing process, the reaction occurred rapidly and released heat massively. Under the attack of hydrogen ions, the structure of TBBFS was destroyed, silicate was depolymerized to form filterable silica, and titanium, magnesium, aluminum, and calcium ions were replaced to form sulfates and enriched on the surface of silica particles. Titanium, aluminum, and magnesium were recovered in the leaching solution, and calcium sulfate and silica were enriched in the residue after leaching. This method could effectively avoid the formation of silica sol during the leaching process and accelerate the solid–liquid separation.
