Product Description

In mineral flotation, controlling the presence of naturally floatable gangue such as mica, talc, and dolomite is critical to achieving high-quality concentrates and optimal recovery rates.
D417, developed by Y&X Beijing Technology Co., Ltd., is an advanced depressant designed to selectively suppress gangue flotation while preserving the floatability of valuable sulfide minerals.
Its targeted action improves flotation circuit efficiency, concentrate grade, and overall plant profitability.

Product Advantages

• Selective Gangue Suppression
  Effectively depresses soft, floatable gangue minerals without compromising copper, gold, or lead recovery.

• Improved Concentrate Purity
  Reduces gangue contamination in concentrates, ensuring higher final metal grades and better downstream processing efficiency.

• Adaptability Across Ores
  Suitable for a wide range of flotation systems, including copper, gold, lead-zinc, and polymetallic ores with variable gangue profiles.

• Operational Simplicity and Stability
  Easy to prepare and apply, D417 maintains stable performance across different plant conditions, even with varying ore compositions.

Performance in Practice

Plant trials and industrial applications have demonstrated that D417:

• Reduces gangue content in final concentrates by 10-30%

• Increases concentrate metal grades while maintaining or improving recovery

• Decreases overall flotation reagent consumption through enhanced selectivity

• Stabilizes flotation circuits, leading to more consistent metallurgical results

Application Guidelines

• Prepare a fresh solution (0.5-1%) prior to dosing.

• Introduce the solution into the flotation conditioner or directly into the flotation stage.

• Adjust dosage based on flotation test results to achieve optimal balance between depression strength and target mineral recovery.

Conclusion

D417 represents a next-generation flotation depressant solution, offering precise gangue control, improved metallurgical outcomes, and enhanced economic benefits for mineral processing operations.
Its proven field performance and versatility make it a valuable component for mines aiming to maximize efficiency, concentrate quality, and operational stability.
