Product Description

D417 is a high-selectivity depressant developed by Y&X Beijing Technology Co., Ltd., designed to optimize flotation performance in ores containing naturally floatable gangue minerals.
It is specifically effective against mica, talc, dolomite, and similar soft gangue materials that commonly reduce flotation selectivity and dilute concentrate quality.

Through its strong selective action, D417 improves valuable mineral recovery rates and enhances concentrate grades, contributing directly to better operational efficiency and economic returns.

Main Features

• Selective Inhibition
  D417 effectively suppresses the flotation of gangue minerals without adversely affecting the floatability of valuable sulfide minerals such as copper, lead, and gold.

• Wide Process Compatibility
  Suitable for use in diverse flotation circuits, including copper, gold, lead-zinc, and polymetallic ores, particularly those challenged by high gangue content.

• Flexible Application
  Can be applied alone or in combination with other flotation modifiers to tailor the reagent scheme according to specific mineralogy and process needs.

• Operational Simplicity
  Easy to dissolve and dose, requiring minimal adjustment to existing plant operations.

Application Benefits

• Improved Selectivity
  Significantly reduces the entrainment of undesirable gangue, leading to higher concentrate purity.

• Higher Recovery and Grade
  By improving separation efficiency, D417 enhances both recovery rates and concentrate metal grades.

• Lower Reagent Consumption
  Supports reduced collector and frother consumption by minimizing non-target mineral flotation.

• Enhanced Process Stability
  Helps stabilize flotation circuits, especially in ores with variable or problematic gangue mineralogy.

Field Results

Extensive industrial applications have demonstrated that D417:

• Increases concentrate grades by up to 10-20% depending on ore characteristics

• Improves flotation recovery consistency in ores with high clay and talc content

• Reduces overall flotation reagent costs through enhanced process efficiency

Conclusion

D417 is a proven depressant solution for mining operations seeking to improve flotation selectivity, upgrade concentrate quality, and optimize plant economics.
Its adaptability, operational simplicity, and superior performance make it an essential component for modern flotation reagent strategies.
