Core Functions of Sodium Hydrosulfide in Mineral Flotation, Leather Tanning and Wastewater Treatment

Sodium Hydrosulfide is an important inorganic sulfide chemical with strong alkalinity and sulfurization performance. It is widely used in mineral processing, leather manufacturing and industrial wastewater treatment industries, and is an essential bulk auxiliary raw material for industrial production and environmental protection treatment.

 

Mineral flotation is the most mainstream application of Sodium Hydrosulfide. It is commonly used in the flotation separation of copper, lead, zinc and other non-ferrous metal ores. It can adjust the pulp pH value, inhibit gangue minerals and improve the flotation efficiency and concentrate grade of target minerals, helping mining enterprises improve resource utilization rate.

 

In leather tanning industry, Sodium Hydrosulfide is used for hair removal and degreasing treatment of animal hides. It can quickly decompose hair and epidermal impurities on the surface of hides, making the leather surface smooth and soft. It has stable treatment effect and low comprehensive cost, and is widely adopted by global leather processing factories.

 

Industrial wastewater treatment is another key application scenario. A large number of heavy metal ions such as copper, lead and mercury are contained in mining and electroplating wastewater. Sodium Hydrosulfide can react with heavy metal ions to form insoluble sulfide precipitation, realizing rapid removal of heavy metals and making wastewater reach discharge standards.

 

With the development of global mining industry, environmental protection policies and leather manufacturing industry, the market demand for Sodium Hydrosulfide remains stable. As a cost-effective industrial auxiliary agent, it has stable export demand in Southeast Asia, Africa, South America and other mining and manufacturing concentrated areas.
