Product Description

Introduction

D486 is a specialized beneficiation reagent developed by Y&X Technology. It is primarily designed to suppress fine-grained carbon minerals, such as graphite, organic carbon, and free carbon, in the flotation processes of colored and rare precious metal ores. With its advanced formulation, D486 enhances mineral selectivity, improves recovery rates, and reduces the use of other reagents.

 

Product Overview

• Appearance: Yellow to yellow-brown solid powder
• Active Components:
  • Xanthan gum
  • Soluble starch
  • Carboxymethyl hydroxyethyl cellulose
• Dosage:
  • Prepare a solution with a concentration of less than 3%.
  • Typical dosage ranges from 50-1000 g/ton of raw ore.
  • Addition points: Stirring drum, flotation tank, or ball mill.
• Packaging:
  • Available in 25 kg bags or 750 kg bulk bags.

 

Key Features

1. Selective Suppression

   • Strongly hydrophilizes the surfaces of graphite, organic carbon, and free carbon.
   • Prevents the adsorption of carbon-based materials on target mineral surfaces.
   • Ensures efficient interaction between collectors and target minerals.

2. Enhanced Recovery

   • Improves the grade and recovery rate of target mineral concentrates (e.g., copper, gold, lead-zinc ores).
   • Reduces competition from hydrophobic carbon minerals during flotation.

3. Reagent Optimization

   • Minimizes the use of collectors and frothing agents, resulting in cost efficiency and better process control.

 

Applications

D486 is widely applied in the flotation processes of:

• Base Metals: Copper, lead, and zinc ores.
• Precious Metals: Gold and other rare metals.
• Carbon Suppression: Specifically for fine-grained carbon minerals such as graphite and organic/free carbon.

 

Storage and Handling

• Storage Guidelines:

  • Keep in a dry, well-ventilated area, protected from heat and sunlight.
  • Follow the First In, First Out (FIFO) principle for optimal usage.
  • Avoid exposure to strong acids, bases, oxidizing agents, and open flames.

• Handling Precautions:

  • Use protective gear, including safety glasses, gloves, and splash shields.
  • Avoid inhalation of vapors or dust.
  • Handle carefully to prevent skin and eye irritation.

 

Environmental Considerations

• Most of the reagent is consumed or degraded during processing.
• Residual amounts are transferred to tailings, and direct release into water systems should be avoided to minimize environmental impact.

 

Conclusion

D486 is a high-performance reagent that enhances flotation efficiency for a variety of metal ores while selectively suppressing carbon minerals. Its innovative formulation helps to achieve better recovery rates and concentrate grades, making it an indispensable tool for mineral processing professionals. With proper storage, handling, and environmental practices, D486 offers a sustainable and efficient solution in the beneficiation industry.
