Products classified under HTS 2603.00.00.10
Chalcopyrite Copper Ore
Chalcopyrite is the most abundant primary copper sulfide mineral, typically containing 20-30% copper content by weight. This ore is mined and concentrated to extract copper, falling under HTS 2603.00.00.10 as it reports the assay copper content without deductions per statistical notes. It is primarily used in smelting processes for copper production.
Bornite Copper Concentrate
Bornite, known as peacock ore, is a copper iron sulfide mineral yielding concentrates with approximately 63% copper content after flotation processing. Classified under HTS 2603.00.00.10 for its reported copper content, it serves as feedstock for copper smelters. The statistical notes mandate reporting pure assay copper without impurities deductions.
Chrysocolla Copper Ore
Chrysocolla is a hydrated copper silicate ore often processed into concentrates with 15-25% copper content, used in copper extraction. It fits HTS 2603.00.00.10 by reporting copper content per assay without deductions. This secondary copper source is valued for oxide ore leaching processes.
Malachite Copper Concentrate
Malachite, a vibrant green copper carbonate hydroxide mineral, produces concentrates averaging 20% copper content suitable for hydrometallurgical recovery. Under HTS 2603.00.00.10, the copper content is reported via assay as per statistical notes. It is commonly heap-leached for copper production.
Covellite Copper Ore Fines
Covellite is an indigo-blue copper sulfide mineral yielding high-grade fines with 66% theoretical copper content after concentration. Classified in HTS 2603.00.00.10 for copper content reporting without deductions. These fines are ideal for direct smelting due to purity.
Azurite-Malachite Mixed Copper Ore
Mixed azurite (copper carbonate) and malachite ores produce blended concentrates with 18-25% copper content, processed via acid leaching. HTS 2603.00.00.10 captures the total copper content per assay standards. Common in oxidized copper deposits.
Enargite Copper-Arsenic Ore
Enargite is a copper arsenic sulfide mineral concentrate with ~48% copper content, processed with arsenic recovery precautions. Falls under HTS 2603.00.00.10 for primary copper content reporting. Used in high-arsenic feed smelters.
Tennantite Copper Ore Concentrate
Tennantite, a copper arsenic sulfosalt mineral, yields concentrates with 40-50% copper after selective flotation. HTS 2603.00.00.10 applies with copper content assayed without deductions. Prevalent in porphyry copper deposits.
Diurleite High-Grade Copper Concentrate
Djurleite is a copper-rich sulfide mineral producing premium concentrates exceeding 50% copper content. Perfectly suited for HTS 2603.00.00.10 copper content statistical reporting. Enhances smelter efficiency due to low gangue.
Antlerite Copper Sulfate Ore
Antlerite is a rare copper sulfate hydroxide mineral forming concentrates with ~38% copper, ideal for solvent extraction. HTS 2603.00.00.10 records the copper content per statistical requirements. Found in arid supergene enrichment zones.
