Product Description

D486 is a specialized flotation depressant developed by Y&X Beijing Technology Co., Ltd., formulated to selectively suppress carbonaceous gangue such as graphite, organic carbon, and free carbon during mineral flotation.
By minimizing the floatability of these unwanted minerals, D486 optimizes the recovery and grade of target sulfide and precious metal concentrates.

Core Functionalities

• Selective Carbon Suppression
  D486 targets carbon minerals without adversely affecting the floatability of valuable metal sulfides.

• Enhanced Flotation Selectivity
  Reduces interference from fine carbon, improving the attachment of collectors to desired mineral surfaces.

• Optimized Metallurgical Performance
  Supports higher concentrate grades, better recovery rates, and improved downstream process efficiency.

Application Areas

• Flotation of copper ores with high carbon content

• Gold flotation circuits encountering organic carbon interference

• Lead-zinc polymetallic ores containing free graphite

• Complex ores requiring enhanced flotation separation precision

Technical Specifications

• Physical Form: Yellow to yellow-brown powder

• Recommended Dosage: 50-1000 g/ton of ore

• Solution Preparation: Prepare as a solution with less than 3% concentration

• Typical Addition Points: Ball mills, conditioning tanks, flotation cells

Packaging and Storage

• Packaging:

  • 25 kg woven bags with liner

  • 750 kg jumbo bags for bulk handling

• Storage:
  Store in a dry, cool, and ventilated place. Protect from direct sunlight, moisture, and extreme temperatures. Follow FIFO inventory practices.

Handling and Safety

• Wear appropriate protective equipment including gloves, goggles, and dust masks during handling.

• Avoid dust inhalation and direct skin or eye contact.

• Refer to the MSDS for detailed handling instructions and emergency measures.

Environmental Impact

D486 residues are primarily retained within concentrates and decomposed during further processing, supporting responsible tailings management.
Disposal should comply with local environmental regulations to prevent potential contamination.

Performance Summary

Field applications have demonstrated that D486:

• Reduces carbon contamination in flotation concentrates by 15-30%

• Improves target metal recovery efficiency

• Decreases collector and frother consumption

• Stabilizes flotation circuit performance in carbon-challenging ores

Conclusion

D486 provides a precise, effective, and reliable solution for flotation plants seeking to control carbonaceous interference and optimize metallurgical results.
It is the preferred depressant choice for mines focused on maximizing concentrate value and achieving operational excellence.
