Sodium Sulphide (Na₂S) 60% represents one of the foundational inorganic salts utilized extensively in modern industrial manufacturing. Structurally classified as an alkali metal sulfide, it presents commercially in the form of yellow or red flakes, depending on the iron content. The chemical concentration of 60% is selected as the optimal equilibrium between solid stability, handling hazard mitigation, and packaging efficiency during maritime and land transit.
As a powerful reducing agent, the chemical efficacy of Sodium Sulphide depends heavily on purity management—most notably, the strict restriction of iron (Fe) contamination. Typically, manufacturers segment these flakes into distinct quality brackets:
Operating a scalable, compliant, and cost-effective Sodium Sulphide 60% plant requires precise thermal management and continuous chemical process control. The traditional industrial synthesis involves the calcination of sodium sulfate (Na₂SO₄) with pulverized coal in a rotary kiln at temperatures ranging between 900°C and 1000°C. Modern plants utilize automated leaching, concentration, and flaking machinery to achieve strict conformity to chemical grades, ensuring low impurity levels and physical uniformity.

The global demand landscape for Sodium Sulphide 60% is shifting due to regulatory frameworks, technological changes, and energy costs. Chinese chemical plants continue to hold a strong market position, driven by raw material availability, efficient supply chain clusters, and process automation.
Key drivers behind China's competitive position in the Sodium Sulphide market include:
In terms of global trends, the chemical industry is moving toward low-iron variations (Fe < 10 ppm) to prevent staining and product degradation in premium applications. Additionally, international buyers are focusing on structural safety in packaging, increasingly opting for heavy-duty UN-approved plastic woven bags and steel drums to prevent hydration and oxidation during sea transit.
Our commitment to compliance, quality, and cross-border trade reliability is recognized by international audit organizations.
We combine high manufacturing capacity with strict quality control to support our global partners' supply chains.
We actively export our chemical products to more than 100 countries and territories. This helps ensure compliance with local shipping regulations and import requirements.
Over 20 years of export experience has enabled us to build streamlined chemical shipping workflows and maintain long-term partnerships with over 1,000 global companies.
Our operations are backed by ISO 9001:2015, German BV audits, SGS raw chemical certifications, FAMI-QS for agricultural sectors, and pre-registered K-REACH clearances.
We work directly with clients to match our manufacturing specifications with their budget and purity requirements, providing clear cost breakdowns.
Our warehouses are located near key logistics hubs in Qingdao, Tianjin, and Xinjiang. This allows us to arrange rapid dispatches and manage export document filings efficiently.
Our sales and technical support teams assist clients through every step of the importing process, from initial cargo clearance to final factory application.
Sodium Sulphide 60% plays a vital role across multiple industrial processes, acting as an essential chemical input for several major sectors:
In B2B mineral extraction, Sodium Sulphide 60% is widely used as a sulfidizing agent in flotation circuits. It helps activate oxidized non-ferrous metal ores, such as malachite (copper oxide) and cerussite (lead oxide), by forming a sulfide film on the mineral surface. This film makes the minerals more receptive to collector chemistries, helping to improve recovery rates. It also serves as a depressant for pyrite and iron sulfides in complex polymetallic separation processes.
Within the tanning industry, Sodium Sulphide is used in dehairing steps. It reduces the disulfide bonds in keratin, allowing hair to be removed cleanly from raw animal hides without damaging the collagen structure. Using low-iron yellow flakes helps prevent dark iron-sulfide staining on the leathers, which is essential for manufacturing premium goods.
In textile production, sulfur dyes require a reducing agent to become water-soluble, allowing them to penetrate cotton fibers. Sodium Sulphide 60% acts as a reducing agent to solubilize the dyes. During the post-dyeing oxidation step, the dyes return to their insoluble state inside the fibers, providing good wash and light fastness properties.
For municipal and industrial wastewater management, Sodium Sulphide is used to precipitate dissolved heavy metals. The sulfide ions react with metal ions (such as mercury, lead, copper, and cadmium) to form highly insoluble metal sulfides. These precipitates can then be filtered out, helping facilities meet local environmental discharge limits.
