Mengda Titanium 90% High Titanium Slag for Titanium Metal Production

Material Overview‌

High titanium slag (HTS) represents a critical intermediate product in global titanium value chains, engineered through advanced electric furnace smelting of ilmenite (FeTiO₃). This energy-intensive metallurgical process selectively separates iron oxides from titanium dioxide, transforming low-grade titanium ores (40-60% TiO₂) into high-purity TiO₂ concentrates graded at 90-92% purity. Unlike conventional by-products or waste residues, HTS serves as a premium feedstock for manufacturing titanium tetrachloride, titanium dioxide pigments, and titanium sponge – the foundational material for aerospace alloys and advanced industrial components.

‌Production Technology‌

The manufacturing process involves three precision-controlled phases:

1. ‌Ilmenite Pre-Treatment‌

   • Raw ilmenite undergoes magnetic separation to remove siliceous gangue minerals
   • Agglomeration with carbon reductants (4-6% coke/coal) into 10-30mm pellets

2. ‌Electric Arc Furnace Smelting‌

   • Operated at 1,550-1,700°C in 25-50MW submerged arc furnaces
   • Key chemical reaction:
     FeTiO₃ + C → TiO₂ (slag phase) + Fe (metallic phase) + CO↑
   • Phase separation achieves 90-92% TiO₂ content in slag

3. ‌Post-Processing‌

   • Water quenching creates amorphous glassy structure
   • Magnetic separation removes residual iron particles (<0.8%)
   • Crushing/screening to produce 5-80mm granules or custom powder grades

‌Technical Specifications‌

• ‌Primary Composition‌:

  • TiO₂: 90.0-92.0% (ISO 5939 certified)
  • FeO: 4.5-6.5% (ferrous oxide content)
  • SiO₂: 2.5-3.8% (silica limit for acid-soluble grades)
  • CaO+MgO: <2.5% (low alkaline earth oxides)

• ‌Physical Characteristics‌:

  • Melting range: 1,650-1,750°C (dependent on crystalline phases)
  • Bulk density: 1.8-2.2 g/cm³ (varying with granulometry)
  • Acid solubility: 96-98% in concentrated sulfuric acid

• ‌Industrial Grades‌:

  • Grade 90: Standard sulfuric acid process feedstock
  • Grade 92: Premium chloride process specification

‌Strategic Advantages in TiO₂ Production‌

1. ‌Process Efficiency‌

   • 35-40% reduction in sulfuric acid consumption vs. raw ilmenite
   • Eliminates iron reduction steps, saving 18-22% operational costs
   • High titanium liquid concentration reduces evaporation energy by 25%

2. ‌Environmental Benefits‌

   • 30% lower CO₂ emissions per ton of TiO₂ produced
   • Zero discharge of iron-containing by-products
   • 95% material utilization rate in closed-loop systems

3. ‌Supply Chain Optimization‌

   • 45% mass reduction from raw ore to HTS lowers logistics costs
   • Compatible with both sulfate and chloride titanium dioxide routes
