Broken Zinc-Lead Ore from Open Pit
Broken zinc-lead ore from open-pit mines contains sphalerite and galena and is crushed prior to milling. It is a run-of-mine ore with zinc as the principal metal, classifiable under tariff item 2608.00.00, with lead content reported statistically.
2608.00.00Calamine Zinc Ore
Calamine is a naturally occurring zinc ore consisting of a mixture of zinc carbonate (smithsonite) and zinc silicate (hemimorphite). It is extracted from oxidized zones of zinc deposits and processed for metallurgical recovery of zinc, making it classifiable under tariff item 2608.00.00.
2608.00.00Flotation Concentrate from Zinc-Lead Mine
Flotation concentrate from zinc-lead mines grades 40-50% zinc with 8-12% lead, produced through beneficiation. It is a zinc concentrate classifiable under tariff item 2608.00.00, with lead content reported statistically.
2608.00.00Hemimorphite Zinc Ore
Hemimorphite is a hydrated zinc silicate mineral found in oxidized zones of zinc deposits. It is a zinc ore used in metallurgical extraction and can be concentrated via flotation, qualifying it for classification under tariff item 2608.00.00.
2608.00.00High-Grade Zinc Ore
High-grade zinc ore refers to direct-shipping ores with zinc content exceeding 30% that require minimal processing before smelting. These ores are naturally occurring minerals used in the metallurgical industry for zinc extraction, falling under tariff item 2608.00.00.
2608.00.00Irish-Type Zinc Ore
Irish-type zinc ore is a carbonate-hosted massive sulfide ore dominated by sphalerite with calcite gangue, typical of deposits like Navan. It is mined for zinc extraction and concentrated via flotation, placing it under tariff item 2608.00.00.
2608.00.00Kipushi-Type High-Grade Zinc-Lead Concentrate
High-grade zinc-lead concentrate from Kipushi-style deposits contains 55% zinc with substantial lead. It is a massive sulfide concentrate classifiable under tariff item 2608.00.00, with lead content reported statistically.
2608.00.00Mississippi Valley Type Zinc-Lead Ore
Mississippi Valley Type zinc-lead ore is a carbonate-hosted sedimentary ore containing sphalerite with 5-15% lead sulfide. It is a zinc ore classifiable under tariff item 2608.00.00, with lead content reported statistically.
2608.00.00Sedex Zinc Ore
SEDEX zinc ore is a sedimentary exhalative deposit type featuring sphalerite in fine-grained sediment-hosted formations, such as those from Sullivan mine. It is a primary zinc ore processed by selective flotation, qualifying under tariff item 2608.00.00.
2608.00.00Smithsonite Zinc Ore
Smithsonite is a zinc carbonate ore formed through supergene enrichment in zinc deposits. It is used in zinc production via roasting and leaching, making it a zinc ore classifiable under tariff item 2608.00.00.
2608.00.00Willemite Zinc Ore
Willemite is a zinc silicate mineral found in oxidized zinc deposits, often exhibiting fluorescent properties. It is a natural zinc ore suitable for concentration and smelting into zinc metal, falling under tariff item 2608.00.00.
2608.00.00Zinc Blende Ore
Zinc blende, also known as sphalerite, is the primary zinc ore consisting mainly of zinc sulfide (ZnS) with minor impurities. It is mined directly from deposits and used for zinc extraction, qualifying under tariff item 2608.00.00.
2608.00.00Zinc-Lead Mixed Ore
Zinc-lead mixed ore is a polymetallic ore containing both zinc and lead sulfides, such as those from Red Dog mine, with zinc as the principal value. It is classified under tariff item 2608.00.00 when zinc predominates and is processed for separate concentration.
2608.00.00Zinc-Lead Sulfide Ore Concentrate
Zinc-lead sulfide ore concentrate primarily contains zinc sulfide (sphalerite) with significant lead content from galena inclusions. It is a zinc concentrate classifiable under tariff item 2608.00.00, with lead content reported statistically.
2608.00.00Zinc Silicate Ore Concentrate Borderline
Zinc silicate ore fines are low-grade materials suitable for heap leaching rather than flotation. They are classified as crude ore under tariff item 2608.00.00 when not fully concentrated, as they are minerals used for zinc extraction in the metallurgical industry.
