Scheelite Tungsten Concentrate
A high-grade concentrate derived from scheelite ore (CaWO4), containing approximately 65-70% WO3 after flotation processing. Classified under HTS 2611.00.60.00 as tungsten concentrates, distinct from raw ores in subheading 2611.00.10.00 due to beneficiation increasing metal content.
Wolframite Tungsten Concentrate
Flotation concentrate from wolframite ore ((Fe,Mn)WO4), typically assaying 60-68% WO3 with iron/manganese impurities. Falls under HTS 2611.00.60.00 specifically for tungsten concentrates prepared for downstream processing into APT or metal.
Recycled Tungsten Ore Concentrate
Concentrate recovered from mining tailings or recycled scheelite/wolframite, processed to 55-65% WO3. Qualifies under HTS 2611.00.60.00 as tungsten concentrates regardless of secondary origin.
APT-Feed Tungsten Concentrate
Purified concentrate specifically prepared as feedstock for ammonium paratungstate (APT) production, with low silica/phosphorus impurities. HTS 2611.00.60.00 applies to all tungsten concentrates including those for chemical processing.
