Low-Grade Chromite Ore (30–36% Cr₂O₃)

Low-Grade Chromite Ore (30–36% Cr₂O₃) from Pakistan

Chromite ore is the only commercial source of chromium, a metal essential in metallurgical, refractory, and chemical industries. Pakistan’s chromite deposits in Balochistan are part of the Tethyan ophiolite belt, one of the world’s most significant chromite-bearing geological formations. Low-grade chromite (30–36% Cr₂O₃) is primarily used in refractory brick production, chemical manufacturing, and foundry applications where metallurgical-grade chrome content is not required.

Typical Composition

• Cr₂O₃: 30–36%

• FeO: 18–24%

• MgO: 10–16%

• Al₂O₃: 12–18%

• SiO₂: 3–8%

• CaO: < 1%

• Cr:Fe Ratio: 1.5:1 to 2:1

Available Forms

• Run-of-mine (ROM) lumps: 10–200 mm

• Crushed lumps: 10–50 mm, 0–10 mm

• Concentrated fines: 0–3 mm

• Custom sizing available

Industrial Uses

• Refractory manufacturing: Chrome-magnesite and magnesite-chrome refractory bricks for steel ladles, cement kilns, and glass furnaces

• Chemical industry: Production of sodium dichromate, chromic acid, chromium sulfate, and other chromium chemicals

• Foundry sand: Chromite sand for casting molds and cores in ferrous and non-ferrous foundries

• Pigments and dyes: Raw material for chrome-based pigments (chrome green, chrome yellow)

• Welding electrode coatings: Chromite fines used as a flux component in welding rod manufacture

Quality Assurance

Each lot includes a Certificate of Analysis reporting Cr₂O₃, FeO, SiO₂, Al₂O₃, MgO, CaO, moisture, and size distribution. Pre-shipment samples are provided for buyer approval. Third-party inspection (SGS or equivalent) can be arranged on request.
