Sodium Sulphide

Sodium Sulphide Flakes (Na₂S) for Leather Tanning, Mining and Industrial Applications

High-Quality Sodium Sulphide for Leather Processing and Industrial Use

Sodium Sulphide (Na₂S) is a dark yellow flake with a characteristic sulfurous odor, widely used in the leather, mining, pulp and paper, textile, and chemical industries. Owing to its excellent reducing and dehairing properties, Sodium Sulphide plays a critical role in leather processing and various industrial operations.

Manufactured to strict quality standards, our Sodium Sulphide Flakes offer consistent performance, high purity, and reliable results across a broad range of applications.

What is Sodium Sulphide?

Sodium Sulphide is an inorganic chemical compound commonly supplied in flake form. It is primarily used as a reducing agent and sulfur source in industrial processes. In the leather industry, Sodium Sulphide is an essential chemical for the liming process, where it efficiently removes hair and opens up the fiber structure before tanning.

Its high reactivity and effectiveness also make it valuable in mineral flotation, paper manufacturing, textile dyeing, and chemical processing.

Key Benefits of Sodium Sulphide

• High-purity Sodium Sulphide flakes with consistent quality.
• Excellent dehairing performance in leather processing.
• Effective reducing agent for industrial applications.
• Suitable for mining and mineral flotation operations.
• Supports pulp and paper manufacturing processes.
• Widely used in sulfur dye production for the textile industry.
• Low insoluble content for improved process efficiency.
• Easy handling and storage in industrial environments.

Applications of Sodium Sulphide

Leather Industry

Sodium Sulphide is extensively used in tanneries during the liming stage as a powerful hair removal agent. It helps break down keratin structures, facilitating efficient dehairing and preparing hides and skins for subsequent tanning operations.

Typical applications include:

• Hair removal during liming.
• Hide and skin processing.
• Fiber opening and swelling.
• Preparation for chrome tanning and retanning.

Mining Industry
In mining and mineral processing, Sodium Sulphide is used in the flotation of oxidized and mixed ores, including:
• Copper ores. 
• Zinc ores. 
• Cobalt ores. 
• Molybdenum ores. 
• Nickel ores. 
Its reducing properties improve the separation and recovery efficiency of valuable metals.

Pulp and Paper Industry

Sodium Sulphide is used in pulping processes to assist in lignin removal and improve pulp quality, contributing to efficient paper production.

Textile Industry

The product is widely used in the manufacture and application of sulfur dyes, providing improved dye fixation and color development.

Chemical Processing

Sodium Sulphide serves as an important raw material and reducing agent in various chemical manufacturing processes, including:

• Metal extraction from aqueous solutions.
• Chemical synthesis.
• Wastewater treatment applications.
• Industrial sulfur chemistry.
