Roasted Molybdenite Concentrate
Roasted molybdenite concentrate is produced by calcining molybdenum sulfide ore to convert MoS2 into MoO3, removing sulfur as SO2. It falls under HTS 2613.10.00.00 as roasted molybdenum ores and concentrates, used primarily for extracting technical-grade molybdic oxide.
Calcined Molybdenum Ore Pellets
Pelletized roasted molybdenum ore, typically from molybdenite, undergoes oxidative roasting to produce MoO3-rich material for further processing. Classified under HTS 2613.10.00.00 as roasted concentrates, ideal for steel alloy production.
Roasted Copper-Molybdenite Flotation Concentrate
Flotation byproduct roasted to recover molybdenum from copper ores, yielding MoO3-rich material. Classified in HTS 2613.10.00.00 for its roasted molybdenum content, common from porphyry deposits.
