Coltan Ore (Tantalite)
Coltan ore, primarily tantalite, is a natural mineral deposit containing tantalum niobate (FeTa2O6) extracted from alluvial or hard-rock mining operations in regions like the Democratic Republic of Congo. It falls under HTS 2615.90.60.60 as tantalum-bearing ore and concentrates, distinguished by its high tantalum content used in electronics manufacturing. The assay quantity of metal content is reported without deductions per statistical notes.
Tantalite Concentrate Grade A
Tantalite concentrate Grade A is a processed ore with minimum 35% Ta2O5 content, produced by gravity separation and magnetic concentration from primary tantalum deposits. Classified under HTS 2615.90.60.60 as tantalum concentrates, it serves as feedstock for tantalum metal extraction in capacitor production. Statistical reporting requires assay-based metal content.
Ethyl Lake Tantalum Ore
Ethyl Lake tantalum ore from Canadian pegmatite deposits contains high-grade tantalum minerals like tantalite and microlite, typically grading 20-40% Ta2O5. It is classified under HTS 2615.90.60.60 for tantalum ores, valued for low uranium/thorium impurities suitable for nuclear and electronics applications.
Pilgangoora Tantalum Ore
Pilgangoora tantalum ore from Western Australia's hard-rock deposit yields concentrates with 25-35% Ta2O5, often as byproduct of lithium mining. It is categorized under HTS 2615.90.60.60 for tantalum ores and concentrates, with metal content assayed per statistical requirements.
