Product Description

In complex flotation systems, the entrainment of naturally floatable gangue minerals such as mica, talc, and dolomite severely impacts concentrate grade and metallurgical performance.
D417, developed by Y&X Beijing Technology Co., Ltd., is an advanced flotation depressant specifically formulated to address these challenges.
Through selective inhibition of gangue minerals, D417 enhances the separation efficiency between valuable metallic minerals and unwanted impurities.

Product Highlights

• Precise Gangue Suppression
  Targets naturally floatable gangue minerals, reducing their presence in the concentrate and improving final product quality.

• Adaptability Across Ore Types
  Suitable for a wide range of flotation circuits involving copper, lead, zinc, gold, and other metallic ores.

• Synergistic Application
  Can be used independently or in conjunction with other depressants to customize flotation performance based on ore characteristics.

• Ease of Use
  Simple preparation as a 0.5-1% aqueous solution, with stable performance across various flotation conditions.

Technical Data

• Physical Form: White powder

• Application Method: Dissolve into 0.5-1% solution; add to the flotation conditioning or flotation stage

• Recommended Dosage: 30-150 g per ton of ore

• Main Components:

  • Guar Gum

  • Carboxymethyl Cellulose (CMC)

  • Sodium Metaphosphate

  • Other selective organic additives

Packaging and Storage

• Packaging Options:

  • 25 kg bags

  • 1000 kg jumbo bags

• Storage Guidelines:
  Store in a cool, dry, and well-ventilated area.
  Keep away from moisture, strong acids, alkalis, and direct heat.
  Shelf life: 24 months if stored under recommended conditions.

Application Advantages

• Higher Concentrate Grades
  By minimizing gangue entrainment, D417 improves concentrate purity, ensuring better downstream processing efficiency.

• Improved Reagent Efficiency
  Reduces the unnecessary consumption of collectors by limiting gangue flotation.

• Enhanced Circuit Stability
  Stabilizes flotation circuit performance, particularly in ore bodies with high clay or talc content.

• Cost Savings
  By improving flotation selectivity, D417 contributes to lower reagent costs and higher metal yields.

Field Validation

D417 has been successfully implemented in multiple flotation plants handling ores with high levels of clay, mica, and talc, achieving:

• Up to 15% improvement in concentrate grade

• Noticeable reduction in gangue content in final concentrates

• More consistent metallurgical recovery across variable feed compositions

Conclusion

D417 offers mining operations a highly effective, reliable, and easy-to-use solution for overcoming the challenges of gangue mineral interference in flotation circuits.
It supports metallurgical improvement, operational efficiency, and overall plant profitability.
