Product Description

Product Description

Depressant D491 is a specialized reagent primarily used for the efficient inhibition of calcium carbonate (calcite) in mineral flotation processes. It is widely applied in fluorite and phosphate flotation, where it enhances the interaction of collectors with target minerals like fluorite, apatite, and others, thereby improving concentrate grades and recovery rates. D491 appears as a yellow to amber solid powder, known for its reliable performance in challenging flotation conditions.

 

Product Features

• Product Name: Depressant D491
• Appearance: Yellow to amber solid powder
• Chemical Components:
  • Active Component: κ-Carrageenan
  • Xanthan Gum
  • Tannic Acid
• Dosage: 50-600 g per ton of raw ore
• Preparation: Dissolve in water to prepare a solution with less than 5% concentration, stirring for 0.5-1 hour until fully dissolved.
• Usage: Add before the collector during flotation.

 

Usage and Application

D491 is effective in inhibiting calcium carbonate (calcite), allowing collectors to focus on target minerals. It is primarily used in:

• Fluorite Flotation: Enhances concentrate grades and recovery rates by suppressing calcite.
• Phosphate Flotation: Effectively separates calcium carbonate to improve the selectivity of the flotation process.

Recommended Usage:

• Prepare a solution with a concentration of less than 5%.
• Add the solution before introducing the collector.
• Dosage: 50-600 g/ton, adaptable based on ore type and flotation conditions.

 

Packaging and Storage

Packaging Options:

• 25 kg/bag
• 50 kg/bag
• 1000 kg jumbo bag

Storage Instructions:

1. Store in a shaded and well-ventilated area.
2. Keep away from strong oxidizing or reducing agents and open flames.
3. Avoid violent impacts during transportation.

 

Safety and Handling

• Avoid the formation of dust and aerosols.
• Prevent direct contact with skin and eyes.
• Ensure personnel receive proper training and follow operating guidelines.
• Wear protective clothing, gloves, and eye/face protection.
• Avoid dust accumulation.

 

Environmental Impact

Most of the reagent remains tied up in concentrates and is destroyed in subsequent processing. Residual amounts transferred to tailings should not be released into water systems.

 

Applications

1. Fluorite Flotation: Suppresses calcite for improved concentrate purity.
2. Phosphate Flotation: Achieves efficient inhibition of calcite, enhancing the recovery of target minerals like apatite.
3. General Inhibition: Suitable for use with other inhibitors to optimize flotation efficiency.

 

Summary

Depressant D491 is a reliable solution for achieving efficient flotation inhibition, particularly in processes involving fluorite and phosphate minerals. With its strong suppression capabilities, user-friendly preparation method, and flexible application dosage, D491 is an essential reagent for enhancing flotation performance and ensuring high-quality concentrate recovery.
