Product Description

D486 is a highly efficient depressant specifically designed to tackle challenges in flotation caused by fine-grained carbon minerals such as graphite, organic carbon, and free carbon. These components, when not managed, can severely impact the recovery and grade of valuable metal concentrates. D486 improves flotation efficiency, reduces reagent consumption, and enhances the overall recovery of target minerals. Below is an in-depth overview of its features, applications, and handling guidelines.

 

1. Product Overview

• Product Name: D486
• Appearance: Yellow to yellow-brown solid powder
• Dosage: Less than 3% solution concentration, with typical usage of 50-1000 g/ton of raw ore
• Composition:
  • Xanthan Gum
  • Soluble Starch
  • Carboxymethyl Hydroxyethyl Cellulose

 

2. Applications and Benefits

Primary Application:
D486 is widely used in the flotation of colored metals and rare precious metal ores, including:

• Copper
• Gold
• Lead-Zinc Ores

Key Benefits:

1. Selective Carbon Suppression:

   • Targets hydrophilic surfaces of graphite, organic carbon, and free carbon, preventing their interference in flotation processes.
   • Minimizes adsorption or coverage on the surface of valuable minerals.

2. Enhanced Mineral Recovery:

   • By suppressing carbon minerals, D486 ensures better interaction between collectors and target minerals, maximizing the efficiency of flotation.

3. Improved Concentrate Grade:

   • Eliminates unwanted carbon contamination, improving the purity of concentrates.

4. Reduced Reagent Dosage:

   • By avoiding carbon interference, D486 reduces the consumption of collectors and frothers, leading to cost savings.

 

3. Mechanism of Action

D486 works by coating the surface of graphite, organic carbon, and free carbon, making them hydrophilic and suppressing their ability to interact with flotation bubbles. This prevents competition with target minerals during flotation, allowing the collector to selectively adsorb on valuable minerals like copper and gold.

 

4. Preparation and Usage

• Preparation:

  • Prepare a solution of D486 with a concentration of less than 3%.
  • Ensure gradual addition of D486 into the stirring drum, flotation tank, or ball mill for uniform mixing.

• Dosage:

  • Recommended range: 50-1000 g/ton of raw ore, depending on ore characteristics and process requirements.

Process Points:

• Add D486 at key stages of the flotation process to achieve maximum suppression efficiency.
• Adjust dosage based on flotation test results to optimize performance.

 

5. Safety and Handling

D486 is manufactured to the highest standards but requires careful handling to ensure safety:

• Personal Protective Equipment (PPE):

  • Safety glasses
  • Splash shields for face protection
  • Natural rubber gloves
  • Protective clothing

• Handling Precautions:

  • Avoid contact with skin and eyes to prevent irritation.
  • Ensure proper ventilation to prevent inhalation of vapors and dust.
  • Operators must read and understand the Material Safety Data Sheet (MSDS) before use.

• Storage Guidelines:

  • Store in a dry, well-ventilated area.
  • Keep away from heat, sunlight, oxidizing agents, and reducing agents.
  • Follow the "first in, first out" principle to maintain product quality.

 

6. Environmental Impact

D486 adheres to environmentally responsible practices:

• Usage in Processing:
  • Most of the reagent binds to the concentrate and is destroyed during subsequent processing operations.
• Tailings Management:
  • Residual D486 is transferred to tailings and must be properly managed to prevent discharge into water systems.

By implementing effective tailings management strategies, environmental risks are minimized, ensuring compliance with sustainability standards.

 

7. Packaging and Shelf Life

• Packaging:
  • Available in 25 kg bags and 750 kg/ton bags for bulk use.
• Shelf Life:
  • 18 months when stored under recommended conditions.

 

Conclusion

The D486 depressant is a highly effective solution for suppressing fine-grained carbon minerals during flotation, enabling the efficient recovery of copper, gold, and lead-zinc concentrates. Its ability to improve concentrate purity, reduce reagent consumption, and enhance overall flotation efficiency makes it an essential reagent for mineral processing.

With proper handling, storage, and environmental safeguards, D486 provides both economic and sustainable benefits, meeting the evolving needs of modern mining industries.
