Several pyrite depressants have been evaluated for their effectiveness in depressing coal pyrite. A novel reagent, NVT, has been synthesized and shown to be selective for the separation of coal from coal pyrite by froth flotation. This organic reagent contains no sulfur group in its structure and ex...
