Lead-Bearing Silver Ore Concentrate
A concentrated ore primarily containing silver with significant lead content, extracted from silver deposits and processed to enrich metal values. Classified under HTS 2616.10.0020 due to its lead content in silver ores and concentrates as specified in the statistical reporting for this subheading. The lead is reported by assay quantity without deductions.
Galena-Rich Silver Concentrate
Concentrate from galena (lead sulfide) deposits associated with silver veins, with lead content exceeding statistical thresholds. Falls under HTS 2616.10.0020 for silver concentrates distinguished by lead content in the HTS hierarchy. Used in smelting for joint extraction of silver and lead.
