Related Products under HTS 2616.10.00

Argentite Ore

Argentite (Ag2S) is a primary silver sulfide ore mined from hydrothermal veins, containing 87% silver by weight. It falls under HTS 2616.10.00 as a silver ore and concentrate used for precious metal extraction. The material is typically crushed and processed via flotation to recover silver concentrates.

Cerargyrite Silver Ore

Cerargyrite, or horn silver (AgCl), is a chloride silver ore found in oxidized zones of silver deposits with up to 75% silver content. Classified under HTS 2616.10.00 for silver ores and concentrates. It is crushed and leached for silver recovery in refining processes.

Native Silver Ore

Native silver ore consists of elemental silver grains embedded in gangue rock from epithermal deposits. It qualifies under HTS 2616.10.00 as unrefined silver-bearing material for concentrate production. Milled and gravity-separated to yield high-grade silver concentrates.

Proustite Silver Ore

Proustite (Ag3AsS3) is a silver sulfosalt ore from low-temperature veins, assaying around 60% silver. Falls under HTS 2616.10.00 as silver concentrate precursor. Flotation and roasting recover silver from arsenic-bearing matrix.

Chlorargyrite Concentrate

Flotation concentrate derived from chlorargyrite ore, enriched to 40-60% silver content for smelting. HTS 2616.10.00 covers such silver-bearing concentrates. Directly fed into cyanidation or smelting circuits.

Acantite Flotation Concentrate

Acantite (Ag2S) flotation concentrate from Mexican silver mines, grading 500-800 oz/ton silver. Classified HTS 2616.10.00 for silver concentrates. Shipped to custom smelters for matte production.
