Products classified under HTS 2616.10.00.10
Silver-Copper Bearing Ore Concentrate
A mineral concentrate derived from silver ores containing a significant copper content, typically processed through flotation to enrich silver and associated copper sulfides. Classified under HTS 2616.10.0010 due to its primary silver content with reportable copper assay for statistical purposes. Used in metallurgical extraction for both silver and copper recovery.
Flotation Concentrate from Silver Ores
Flotation-processed concentrate from polymetallic silver ores featuring copper sulfides like chalcopyrite, with silver as tellurides or native form. Falls under HTS 2616.10.0010 as silver ore concentrates with copper content reported separately. Essential feedstock for smelters extracting both precious and base metals.
Chalcopyrite-Silver Ore Concentrate
Concentrate rich in chalcopyrite (copper-iron sulfide) intergrown with silver minerals from epithermal deposits, beneficiated for metal recovery. HTS 2616.10.0010 captures its silver ore nature with copper content for trade statistics. Commonly imported for integrated precious/base metal refineries.
Polymetallic Silver-Copper Flotation Product
Beneficiated flotation product from silver-lead-zinc-copper ores, enriched for silver with notable copper sulfides. Classified in 2616.10.0010 for silver concentrates, reporting copper content statistically. Key input for complex ore processing facilities.
Native Silver-Copper Mineral Concentrate
Concentrate featuring native silver grains with copper-native associations from oxidized zones, milled and floated. HTS 2616.10.0010 applies for silver ore concentrates with copper metric. Sourced from historic districts like Cobalt, Ontario.
