Bessemer Nickel Matte
Bessemer nickel matte is an intermediate product of nickel metallurgy, produced during the pyrometallurgical processing of nickel ores. It contains approximately 40-60% nickel and is used as a feedstock for further refining into pure nickel.
7501.10.00Converter Nickel Matte
Converter nickel matte is produced during the converting stage of nickel smelting, where impurities are oxidized and removed. It typically contains 45-75% nickel and is a key intermediate for nickel refining.
7501.10.00Electric Furnace Nickel Matte
Electric furnace nickel matte is produced in submerged arc furnaces from calcine feed, achieving a nickel content of about 70% with low impurities. It is a standard intermediate product in nickel metallurgy.
7501.10.00Falconbridge Process Nickel Matte
Falconbridge process nickel matte is produced using oxygen-flash converting technology, yielding high-quality matte with over 75% nickel content. It is an intermediate product used in nickel refining.
7501.10.00High-Grade Nickel Matte
High-grade nickel matte is a molten intermediate product from nickel smelting, containing approximately 70-80% nickel along with copper, iron, and sulfur impurities. It is a primary feedstock for nickel refining.
7501.10.00INCO Flash Converter Matte
INCO flash converter matte results from the flash smelting process, producing continuous high-grade nickel matte streams. It is an intermediate product of nickel metallurgy, classified under this tariff item.
7501.10.00Laterite Ore-Derived Nickel Matte
Laterite ore-derived nickel matte is produced from lateritic ores via high-pressure acid leaching followed by sulfide precipitation. It typically contains 40-60% nickel and is classified as nickel matte.
7501.10.00Norilsk-Style High Copper Nickel Matte
Norilsk-style high copper nickel matte contains elevated copper levels (20-30%) typical of Russian sulfide ore processing. It is classified as nickel matte when nickel predominates by weight.
7501.10.00Pierce-Smith Converter Matte
Pierce-Smith converter matte is generated in horizontal converters during the converting stage of nickel production. It features high nickel and reduced sulfur content, making it a standard nickel matte.
7501.10.00Sudbury Basin Slow-Cooled Nickel Matte
Sudbury Basin slow-cooled nickel matte is produced from Canadian shield ores and allowed to solidify gradually to control mineralogy. It contains 60-70% nickel and is classified as conventional nickel matte.
