They can offer a significant economic advantage in the flotation of minerals by reducing smelter penalties, increasing grades and recovery of mineral concentrates.

Key Benefits:

  • Improved grade and recovery
  • Depression of penalty elements
  • Excellent EHS profile
  • Non-toxic
  • Sustainable products from renewable sources

Our flotation depressants are proven to be effective on a variety of gangue minerals:

  • Sulfide minerals, like pyrite, pyrrhotite, arsenic and bismuth sulfides
  • Oxide minerals, like silicates, talc and calcite
  • Clays and graphite
