Nickel Oxide Sinters
Nickel oxide sinters are intermediate products produced by sintering nickel oxide ores or concentrates at high temperatures to form porous agglomerates. They are used in nickel metallurgy as a feedstock for further refining into nickel metal or chemicals. This product falls under HTS 7501.20.00.00 as an intermediate product of nickel metallurgy.
Ferronickel Oxide Sinters
Ferronickel oxide sinters are agglomerated intermediates containing nickel and iron oxides, produced from laterite ores for use in ferronickel production. They serve as a key step in pyrometallurgical processing before smelting. Classified under HTS 7501.20.00.00 due to their role as nickel metallurgy intermediates.
Calcined Nickel Oxide Briquettes
Calcined nickel oxide briquettes are compacted, heat-treated intermediates made from nickel oxide fines, used as charge material in electric arc furnaces for nickel alloy production. The briquetting improves handling and reduces dust loss. This fits HTS 7501.20.00.00 as other intermediate products of nickel metallurgy.
Nickel Laterite Ore Sinters
Sinters produced from nickel laterite ores through rotary kiln agglomeration, containing nickel oxide with magnesium and silica gangue materials. Used directly in rotary kiln-electric furnace (RKEF) process for ferronickel. HTS 7501.20.00.00 covers these as nickel metallurgy intermediates.
Nickel Cobalt Oxide Sinters
Intermediate sinters containing mixed nickel and cobalt oxides from hydroxide precipitation and thermal treatment, used in battery material precursor production. The sintering creates stable oxide morphology for further processing. Classified under HTS 7501.20.00.00 for nickel metallurgical intermediates.
Pelletized Nickel Oxide Intermediates
Pelletized forms of nickel oxide produced via green pelletizing and induration, serving as uniform feedstock for submerged arc furnaces in stainless steel production. Pellets offer better gas permeability than sinters. HTS 7501.20.00.00 includes these pelletized metallurgical intermediates.
