Sodium sulphide, with a chemical formula of Na2S, is a vital industrial chemical that finds extensive applications in various industries. In particular, the 60% industrial grade sodium sulphide plays a crucial role in the field of ore flotation.

During the flotation process, sodium sulfide is added as a depressant to selectively inhibit the flotation of certain minerals. It reacts with metal ions, forming metal sulfides that are less floatable, thus improving the selectivity of the flotation process. By controlling the dosage of sodium sulfide, the desired minerals can be effectively separated from the gangue minerals.

In the hydrometallurgical extraction of metals, sodium sulfide is used as a lixiviant or leaching agent. It helps to dissolve the target metal from the ore or concentrate, facilitating its subsequent extraction and purification. Sodium sulfide reacts with metal ions, forming soluble metal sulfides that can be easily separated from the solid residue.

Furthermore, sodium sulfide is also employed in the production of certain chemicals used in mineral processing. It can be used as a reducing agent in the production of metallic powders or as a sulfur source in the synthesis of various compounds.

The application of 60% industrial sodium sulphide in the field of ore flotation is of paramount importance. Its role as a sulphidizing agent and pH regulator significantly improves the efficiency and effectiveness of the separation process. Furthermore, it offers advantages in terms of environmental sustainability. With its wide availability and various benefits, 60% industrial sodium sulphide continues to be a crucial component in the mining industry’s pursuit of efficient and sustainable mineral processing.
