Product Description

Introduction

In the complex world of mineral processing, efficient separation of minerals requires precision, selectivity, and reliable reagents. Depressant D451, a highly effective flotation depressant, stands out as a game-changing solution for the separation of copper, lead, sulfur, and pyrite minerals. Its non-toxic nature, small molecular composition, and strong inhibitory effects make it a versatile and essential reagent for modern flotation processes.

Designed to replace traditional depressants, Depressant D451 delivers superior performance across a range of ore types and flotation environments, offering enhanced separation results while maintaining environmental and operational safety.

 

1. Product Overview

• Product Name: Depressant D451
• Model: D451A, D451B
• Appearance: Yellow brown to dark red liquid
• Active Component: Sodium Salt
• Dosage: Varies based on ore type, typically 100-500 g/t

The unique composition of D451 ensures reliable and consistent performance in suppressing unwanted minerals, improving flotation efficiency, and simplifying the separation of copper, lead, and sulfur-bearing minerals.

 

2. Applications of Depressant D451

Depressant D451 is highly effective in a range of flotation processes, where selective depression of specific minerals is required:

A. Copper-Molybdenum Flotation

• Used as a depressant in copper-molybdenum ore flotation circuits to inhibit the flotation of pyrite and other sulfide minerals.
• Replaces sodium sulfide, offering a safer and more stable solution with improved performance.

B. Copper-Lead Separation

• In the flotation of copper-lead mixed concentrates, D451 acts as an excellent depressant for chalcopyrite, allowing for the efficient separation of copper and lead minerals.
• Its strong inhibitory effect enhances concentrate purity and reduces interference between copper and lead during flotation.

C. Zinc-Sulfur Separation in High pH Conditions

• When used with copper sulfate to activate sphalerite in high-pH environments, Depressant D451 effectively depresses pyrite and pyrrhotite, enabling clear separation of zinc and sulfur minerals.
• This ensures higher zinc recovery while minimizing the flotation of sulfur-bearing impurities.

 

3. Key Features and Benefits

1. Strong Inhibitory Effect

   • D451 provides significant inhibition of copper, sulfur, and pyrite, enabling selective flotation of target minerals.

2. Non-Toxic and Safe

   • As a non-toxic depressant, D451 ensures improved safety for both operators and the environment compared to traditional alternatives like sodium sulfide.

3. Versatility Across Ore Types

   • Performs effectively in various flotation systems, including copper-molybdenum, copper-lead, and zinc-sulfur separation.

4. Cost-Effective Solution

   • Requires relatively low dosages (100-500 g/t), reducing reagent consumption while maintaining excellent performance.

5. High Stability in High-pH Environments

   • Maintains stability and effectiveness in alkaline flotation circuits, improving separation efficiency in high-pH pulps.

6. Environmental Compliance

   • Reduces the use of hazardous depressants, aligning with modern environmental regulations and sustainability goals.

 

4. Mechanism of Action

Depressant D451 works by selectively adsorbing onto the surfaces of specific minerals, inhibiting their hydrophobicity and preventing them from attaching to air bubbles in the flotation cell.

• Pyrite and Pyrrhotite Suppression:
  In high-pH environments, D451 interacts with the surfaces of pyrite and pyrrhotite, rendering them hydrophilic and ensuring their depression.

• Copper and Lead Separation:
  By suppressing chalcopyrite, D451 enables the clean and efficient separation of copper and lead minerals, improving concentrate quality.

• Sulfur Suppression in Zinc Activation:
  When copper sulfate is used to activate sphalerite, D451 ensures pyrite is depressed, allowing for precise zinc-sulfur separation.

 

5. Recommended Usage

To achieve optimal results with Depressant D451:

1. Dosage:

   • Typical dosage ranges between 100-500 g/t, depending on the ore type and flotation conditions. Laboratory flotation tests are recommended to determine the precise dosage.

2. Addition Point:

   • Introduce D451 into the flotation system as a raw liquid reagent to ensure proper dispersion and interaction with mineral surfaces.

3. Combination Use:

   • Combine with copper sulfate in zinc flotation for sphalerite activation while suppressing sulfur minerals.
   • Use alongside collectors and frothers as part of a comprehensive reagent scheme for copper-molybdenum or copper-lead separation.

 

6. Safety and Handling

While Depressant D451 is non-toxic, proper safety measures must be followed:

• Personal Protective Equipment (PPE):

  • Use safety glasses, gloves, and splash-resistant clothing to prevent skin or eye contact.

• Storage:

  • Store in a cool, dry, and ventilated warehouse.
  • Avoid exposure to ignition sources or static discharge.

• Handling:

  • Use non-sparking tools, and ensure all equipment is properly grounded to avoid static buildup in explosive environments.

 

7. Packaging and Storage

• Packaging Options:

  • Available in drums, IBC containers, and bulk shipments to accommodate varying operational needs.

• Storage Conditions:

  • Keep in a dry, ventilated area, away from direct sunlight, heat, and ignition sources.
