Chromite Fines

Chromite Fines from Pakistan

Chromite fines are a fine-grained, dense powder produced from chromite ore through mining, crushing, and screening operations. The material is dark grey to black in color with a high specific gravity and excellent thermal properties. Pakistan’s Balochistan chromite belt is one of the world’s most significant chromite-producing regions, generating large volumes of chromite fines suitable for a wide range of industrial applications.

Key Properties

• Appearance: Fine dark grey to black powder

• Specific Gravity: 4.0–4.6

• Bulk Density: 2.2–2.8 g/cm³

• Refractoriness: > 1800 °C

• Thermal Conductivity: High

• pH: 7–9

• Moisture: < 5%

Industrial Uses

• Foundry sand: Chromite fines are used as specialty molding and core sand in steel, iron, and non-ferrous foundries — valued for high refractoriness, thermal conductivity, resistance to metal penetration, and chemical inertness against molten metal

• Refractory manufacturing: Raw material for chrome-mag ramming masses, gunning mixes, patching compounds, monolithic refractories, and refractory coatings for steelmaking vessels, cement kilns, and glass furnaces

• Chemical manufacturing: Feedstock for sodium dichromate, chromic acid, chromium sulfate, chromium oxide green, and other chromium chemical production

• Welding consumables: Chromite fines as a flux and coating ingredient in welding electrode and flux-cored wire formulations

• Sintering and pelletizing: Agglomerated into sinter or pellets for submerged arc furnace feed in ferrochrome production

• Pigments: Base material for chrome oxide green pigment used in paints, ceramics, and construction

• Specialty cements and mortars: Additive for heat-resistant cements, refractory mortars, and specialty grouts

Quality Assurance

Each lot includes a Certificate of Analysis reporting Cr₂O₃, FeO, SiO₂, Al₂O₃, MgO, CaO, P, S, moisture, and particle size distribution. Pre-shipment samples are provided for buyer approval. Third-party inspection (SGS, Intertek, or equivalent) can be arranged. TML certification is provided for bulk vessel shipments as per IMSBC Code.
