Pre-treatment titanium-containing blast furnace slag mainly contain following several method.(1) prepare the material of construction such as cement and concrete: but containing TiO
2the strong crystallizing power of blast furnace slag, makes the activity of cement of production poor; (2) acidic process: use sulfuric acid or Leaching in Hydrochloric Acid titanium-containing blast furnace slag separation and Extraction TiO
2but higher foreign matter content in slag, makes this technique acid consumption large, cost is high, and spent acid and the tailings of generation are many, and environmental pollution is serious; (3) alkaline process is processed: use NaOH or Na
2cO
3separation and Extraction TiO
2.But alkaline process complex treatment process, the cost recovery of sodium salt is high, the volatilization heavy corrosion experimental installation of sodium salt under high temperature; (4) high temperature cabonization low temperature chlorination method: make the TiO in blast furnace slag by carburizing reagent
2be converted into TiC, then by chlorination reaction, make it chlorination and become TiCl
4, as the raw material of preparing titanium sponge or titanium white, a large amount of CaCl that generate in process
2and MgCl
2have the advantages that boiling point is high, viscosity strong, with liquid phase, exist, make chlorination plant be difficult to long-term normal operation; (5) high-temperature selective crystallization process: the titanium disperseing in titanium-containing blast furnace slag is enriched in to (uhligite or anosovite) in a certain titaniferous phase, then by beneficiation method, realize the separated of titaniferous and impurity phase, but still cannot successfully accomplish this point at present; (6) prepare iron alloy: adopt ferrosilicon, road to adopt ferrosilicoaluminum as reductive agent, under molten state, to reduce titanium-containing blast furnace slag, prepare silicon titanium, sial ferro-titanium, need titanium, silicon and aluminium as the steel grade of alloying agents seldom simultaneously, limited the extensive use of this method.
