Gold Dressing Agent

Gold Dressing Agent

Chemical Composition: Mainly sodium cyanide (NaCN) or alternatives (e.g., thiourea, thiosulfate).
CAS Number: 143-33-9 (Sodium Cyanide); 62-56-6 (Thiourea)
Appearance: White crystalline powder or liquid, odorless or with a slight characteristic odor.

Key Features

• Efficient Gold Extraction: Effectively dissolves gold particles in gold ore to form soluble gold-cyanide complexes.

• High Selectivity: Highly selective for gold with minimal interference from other metals.

• Rapid Reaction: Quickly reacts with gold under suitable conditions, improving extraction efficiency.

• Good Stability: Stable under alkaline conditions, suitable for large-scale industrial applications.

• Eco-Friendly Alternatives: Some products use environmentally friendly formulations to reduce pollution.

Applications

1. Gold Extraction

• Used in the leaching process of gold ore to extract gold through cyanidation.

• Suitable for low-grade and refractory gold ores.

2. Tailings Treatment

• Used to recover residual gold from tailings, improving resource utilization.

• Suitable for redevelopment and resource recovery in old mining areas.

3. E-Waste Recycling

• Used to extract gold and other precious metals from electronic waste.

• Suitable for recycling precious metals from waste circuit boards, mobile phones, and other electronic products.

4. Other Precious Metal Extraction

• Used for the extraction and separation of silver, platinum, and other precious metals.

Safety and Handling

• Storage: Store in a cool, dry, well-ventilated dedicated warehouse, away from acids, oxidizers, and flammable materials.

• Safety Precautions:

• Wear full protective equipment (e.g., gas masks, protective clothing, gloves, goggles) during handling.

• Avoid direct contact with skin, eyes, and inhalation of dust or gas.

• Emergency Measures:

• In case of leakage, immediately isolate the area and use specialized absorbent materials for cleanup.

• If skin or eye contact occurs, rinse immediately with plenty of water and seek medical attention.

• Transportation: Transport in accordance with regulations for highly toxic chemicals, using dedicated vehicles and equipped with emergency response equipment.

Key Advantages

• Efficient Extraction: Significantly improves gold recovery rates and reduces production costs.

• Strong Adaptability: Suitable for various types of gold ores and extraction processes.

• Eco-Friendly Options: Some products use low-toxicity or non-toxic formulations to minimize environmental impact.

Precautions

• Professional training is required before use to ensure operators are familiar with safety protocols and emergency measures.

• Strictly comply with local laws and regulations for storage, transportation, and use.
