Selective Depressant D421B
Unlock superior mineral separation with our advanced flotation depressant. Designed to selectively suppress problematic minerals like serpentine and pyrite, D421B ensures cleaner concentrates and higher recovery rates, especially in challenging polymetallic ore processing.
- Achieve effective serpentine control by forming a hydrophilic film, significantly reducing its floatability as tailings.
- Stabilize fine gangue through charge neutralization, preventing adherence to sulfide mineral surfaces for cleaner separation.
- Suppress pyrite even in mild pH conditions via surface adsorption and oxidation, creating a passive, hydrophilic layer.
- Benefit from functionality at reduced alkalinity, allowing for lower lime consumption and improved process stability in serpentine-rich ores.
Key Advantages
