Fluorspar metallurgical grade

Description

1. Product Overview
Metallurgical Grade Fluorspar (CaF₂) is a critical fluxing agent engineered to lower slag viscosity and remove impurities in primary steelmaking and cement production. Its core value proposition lies in accelerating smelting cycles, reducing energy consumption per ton, and extending furnace refractory life. As global steel decarbonization intensifies, high-performance fluorspar is strategically vital for optimizing blast furnace and electric arc furnace (EAF) productivity while maintaining strict cost per ton of output.

2. Key Specifications & Technical Characteristics

• Chemical Composition: CaF₂ 75–85% (typical); SiO₂ ≤ 12%; CaCO₃ ≤ 4%; S ≤ 0.2%; P ≤ 0.08%

• Purity Level: Standard metallurgical grade (≥75% CaF₂) – available in 75%, 80%, and 85% variants

• Physical Form: Crushed lump (dominant) or fine granule; off-white to light grey

• Particle Size: 10–70 mm (90% min within range); custom sizing (5–30 mm / 20–80 mm) available on request

• Bulk Density: 1,600–1,800 kg/m³ (loose), 2,100–2,300 kg/m³ (compacted)

• Moisture: ≤ 1.5%

• Packaging Options: 1 MT big bags (weather-proof), 50 kg multilayer paper/PP bags, or direct vessel bulk loading

• Shelf Life: 24 months when stored in dry, covered conditions away from strong acids

3. Core Industrial Applications

• Primary Steelmaking (BOF & EAF): As a flux to dissolve gangue (silica, alumina) and sulfide inclusions. Advantage: Reduces slag melting point to ~1,300°C – cuts energy use by 5–8% vs. lime-only flux blends.

• Ferroalloy Production: Enhances recovery of chromium, manganese, and nickel from ores. Advantage: Higher alloy yield per furnace charge.

• Cement Manufacturing (Mineralizer): Lowers clinker formation temperature. Advantage: Increases kiln throughput by 10–12% without additional fuel.

• Welding Flux (Submerged Arc): Used in agglomerated flux formulations. Advantage: Superior arc stability and slag detachability compared to rutile-based fluxes.

4. Competitive Advantages

• Quality Consistency: Lot-to-lot CaF₂ variation < 1.5% – guaranteed via ISO 9001:2025-certified ICP-OES and XRF testing.

• Supply Reliability: Multi-source mine integration (Mexico, China, South Africa) ensures 12-month rolling contracts with force majeure protection.

• Logistics Capability: Dedicated breakbulk and container loading terminals; typical lead time 15–25 days FOB to major ports (Rotterdam, Houston, Busan, Santos).

• Cost Competitiveness: Priced at a 10–12% discount to spot index (Metal Bulletin / Fastmarkets) on annual fixed-volume agreements.

• Sustainability: Zero acid-waste processing; available with verified Scope 3 emissions data and non-conflict mining certification.

• Technical Support: Full MSDS, commercial assay per shipment, and metallurgical modeling (blast furnace slag optimization) provided digitally.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 20 MT (one standard 20‑ft container) for bagged product; 500 MT for bulk vessel loading.

• Loading Capacity (MT per container):

  • 20‑ft standard container: 22–25 MT (bulk or 1 MT jumbo bags)

  • 40‑ft standard container: 27–28 MT (jumbo bags only due to weight limits)

  • Note: Bulk lump cargo ships at 1,500–5,000 MT per vessel hold.
