Columbite – Niobium-Tantalum Ore

Overview

Ayudidibe Mega Ventures (Nig) Ltd specializes in the mining, processing, and export of high-grade Columbite – a strategic ore rich in niobium (Nb) and often containing tantalum (Ta). Our columbite is sourced from ethically operated mining sites and supplied to industries involved in electronics, aerospace, and alloy manufacturing.

Product Description

• Product Name: Columbite (FeNb₂O₆)
• Typical Niobium (Nb₂O₅) Content: 35% – 55%
• Tantalum (Ta₂O₅): May be present in varying traces (5% – 20%)
• Form: Mineral concentrate / raw ore
• Color: Black to brownish-black, submetallic to metallic luster
• Density: High specific gravity (5.2–7.0 g/cm³)
• Packaging: 50 kg sacks or 1MT bulk bags
• Documentation: Mineral assay, export license, certificate of origin

Industrial Applications

Columbite is critical in:

• Alloy Production: Used in high-strength steel and superalloys for turbines and engines
• Capacitors & Electronics: Niobium-tantalum oxides are essential in capacitor manufacturing
• Aerospace & Defense: Structural materials requiring high thermal and corrosion resistance
• Nuclear Technology: Niobium is used in nuclear reactor components

Quality & Processing

We employ mechanical separation, magnetic sorting, and gravity concentration to extract high-grade columbite from mined ore. Each shipment is tested by ISO-accredited labs to confirm Nb₂O₅ and Ta₂O₅ content. Moisture content and trace impurities are controlled to meet international specifications.
