SODIUM SULFIDE is widely used in the flotation of copper, molybdenum, cobalt, lead, zinc, nickel and other ores. When sodium sulfide is dissolved in water, it dissociates into HS- and S2- ions, which react with metal ions on the surface of sulfide minerals, forming insoluble sulfide precipitates or altering the mineral surface properties, thereby affecting the flotation behavior of the minerals. For example, when it interacts with oxide ores of non-ferrous metals, a layer of sulfide mineral film is formed on the mineral surface, enhancing the floatability of the mineral. Na2S has multiple uses in metal mining, acting as a depressant, sulphidizing agent, desorbent, and more. Additionally, Na2S is commonly used as an oilfield chemical, widely applied in oilfield development, especially in cases where it is necessary to improve crude oil flow properties and enhance recovery rates.

SODIUM SULFIDE plays a crucial role in the textile printing and dyeing industry, where it serves as a dye reducing agent, dyeing auxiliary, fabric printing auxiliary, fabric activator, and helps improve dyeing uniformity and color brightness. The application of sodium sulfide in the textile printing and dyeing industry also lies in enhancing production efficiency. Due to its easy solubility and excellent stability, sodium sulfide can be used under different process conditions and complete dyeing, printing, and activation processes in a relatively short time, thus improving production efficiency. Sodium sulfide is cost-effective and can replace some expensive reducing agents, thereby reducing production costs. This is of significant economic significance for textile printing and dyeing enterprises.

SODIUM SULFIDE is widely used in the leather industry and is an indispensable part of the leather-making process. Sodium sulfide plays multiple roles in leather production, such as a dehairing agent for raw hides, a soaking aid for softening dry hides, and a tanning agent. Additionally, sodium sulfide offers many environmental advantages in the leather industry. The wastewater and waste generated during the tanning process using sodium sulfide are relatively minimal, easy to treat, and do not produce harmful heavy metal waste, resulting in less environmental pollution. Furthermore, sodium sulfide can be combined with other tanning agents and processes to improve the stability and durability of leather.

SODIUM SULFIDE is commonly used as a cooking agent in the papermaking industry. Through the cooking process, sodium sulfide accelerates the separation of lignin and hemicellulose in plant fiber raw materials, thereby improving the quality and yield of pulp and enhancing paper performance. Although the papermaking industry is a highly polluting sector, sodium sulfide is considered a relatively environmentally friendly chemical. From an economic perspective, the use of sodium sulfide increases the efficiency and output of paper production lines, reducing production costs. With the continuous development of papermaking technology and the increasing demand for environmental protection, the application prospects of sodium sulfide in the papermaking industry will become even broader.
