Galena Lead Ore
Galena is the primary mineral form of lead sulfide (PbS), a dense metallic ore typically found in hydrothermal veins. It is mined and processed as lead ore and concentrate under HTS 2607.00.00 because it contains over 50% lead by weight and is used directly for lead extraction. The coarse crystalline structure makes it suitable for crushing and flotation concentration.
Cerussite Lead Carbonate Ore
Cerussite (PbCO3) is a lead carbonate mineral often found in oxidized zones of lead deposits, appearing as white, adamantine crystals. Classified under HTS 2607.00.00 as a lead ore when lead content exceeds threshold levels post-concentration. It requires roasting to convert to oxide before smelting.
Anglesite Lead Sulfate Ore
Anglesite (PbSO4) forms as a secondary mineral in oxidized lead deposits, often colorless or gray prismatic crystals. It qualifies as lead ore under HTS 2607.00.00 when concentrated for lead recovery via reduction processes. Commonly associated with galena in mining operations.
Lead-Zinc Flotation Concentrate
A processed concentrate from froth flotation separating lead sulfides from gangue and zinc minerals in polymetallic ores. Falls under HTS 2607.00.00 as lead-bearing material with 50-70% PbS content. Primarily used in primary lead smelters.
Mississippi Valley Type Lead Concentrate
Concentrate from MVT deposits like those in Missouri, rich in high-grade galena with minimal impurities. Classified under HTS 2607.00.00 due to its lead-dominant composition (60-85% Pb). Known for low silica content ideal for direct smelting.
