Titanium Refining Slag

Description

1. Product Overview
Titanium Refining Slag is a high-concentration, processed secondary titanium material produced through the smelting of ilmenite to remove a significant portion of the iron content, yielding a Ti02 grade of 70–85%. It serves as the primary feedstock for the production of titanium dioxide pigment and titanium sponge (the precursor to titanium metal). Its key value proposition lies in delivering a substantially higher TiO2 yield per ton than natural ilmenite, reducing energy consumption, acid consumption, and waste generation in downstream chemical processes. Strategically, this product is critical for industrial buyers seeking to secure high-quality titanium units while lowering their environmental footprint and operating costs in an increasingly carbon-constrained global market.

2. Key Specifications & Technical Characteristics

• Chemical Composition: TiO2: 70–85% (standard grade: 75%; premium grade: 80–85%), FeO: 8–15%, residual MgO + CaO < 3%, SiO2 < 2%

• Purity / Grade: Minimum 70% TiO2; available in 75%, 80%, and 85% concentrate grades

• Physical Form: Angular granular slag, dark grey to black

• Particle Size Distribution: 0.1 mm – 5 mm (standard); custom milling to < 0.045 mm available for pigment feed

• Bulk Density: 2.2 – 2.5 g/cm³

• Moisture Content: < 0.5% as shipped

• Packaging Options: 1.5 MT bulk bags, 50 kg industrial woven sacks, or direct vessel loading for bulk cargo

• Shelf Life: Indefinite when stored in dry, covered conditions; avoid prolonged contact with moisture

3. Core Industrial Applications

• Primary Industry 1 – Titanium Dioxide (TiO₂) Pigment Manufacturing (Sulfate & Chloride Process): Used as premium feedstock. Outperforms natural ilmenite by reducing sulfuric acid consumption by up to 30% and solid waste (copperas) by over 40%, directly lowering both chemical costs and disposal liabilities.

• Primary Industry 2 – Titanium Metal / Titanium Sponge Production (Kroll Process): Converted into TiCl4, then reduced to titanium sponge. Compared to rutile, titanium refining slag offers a more stable price point and consistent chlorination reactivity, improving furnace throughput by 8–12%.

• Primary Industry 3 – Welding Electrode Fluxes & High-Temperature Refractories: Provides a stable titanium source for slag systems in basic-coated electrodes. Its low volatile content and controlled particle size reduce spatter and improve arc stability versus blended ilmenite sands.

• Efficiency Advantage: Higher TiO2 per ton means fewer shipments, lower freight cost per unit of titanium, and reduced inventory carrying cost for large-volume buyers.

4. Competitive Advantages

• Quality Consistency: Batch-to-batch variation of TiO2 < ±1.5% — certified by ISO 17025-accredited lab reports with every shipment. Traceable from furnace to container.

• Supply Reliability: Long-term contracts with three vertically integrated smelting facilities (South Africa, Canada, Norway), ensuring 24/7 load-out capacity. No single-source dependency.

• Logistics Capability: Dedicated warehousing in Rotterdam, Houston, and Shanghai for just-in-time delivery. Average lead time: 14 days for spot orders; 7 days for contract customers.

• Price Competitiveness: Priced 12–18% below premium rutile on a per-unit TiO2 basis, with fixed quarterly pricing available for annual volumes above 10,000 MT.

• Sustainability: Produced using hydro-powered furnaces where available. Lower CO₂/ton TiO2 than ilmenite smelting or direct rutile mining. Full Life Cycle Assessment (LCA) data provided upon NDA.

• Technical Support: Free process optimization audit for first-time buyers; on-site blending and slag-ore optimization modeling included for contracts > 5,000 MT.
