Product Introduction
Sodium Sulfide (Na₂S) is a versatile inorganic reagent widely employed in flotation processes. It primarily functions as a sulfidizing agent for oxide minerals of copper, lead, and zinc, forming a hydrophobic sulfide film on their surfaces to enable effective collector adsorption. Simultaneously, it serves as a powerful depressant for sulfide minerals, notably in copper-molybdenum separation where it selectively depresses copper sulfides. Its action involves creating a reducing environment and displacing collectors from mineral surfaces. This dual functionality, combined with its role as a pH modifier, makes it invaluable for processing complex and mixed ores, enhancing both selectivity and metal recovery in an economically efficient manner.
Product Advantage
1.Sodium sulfide provides crucial advantages in mineral flotation through its dual functionality. It serves as both an effective sulfidizing agent for oxide minerals and a selective depressant for sulfide minerals. This enables efficient recovery of oxidized copper, lead, and zinc ores while facilitating critical separations like copper-molybdenum bulk concentrates.
2.The reagent offers significant economic and operational benefits. As a widely available and cost-effective chemical, it helps reduce overall reagent consumption while maintaining high recovery rates. Its ability to create reducing conditions and modify mineral surfaces makes it indispensable in complex ore processing, contributing to improved selectivity and operational efficiency across various flotation applications.

Product Uses
Main Purpose: Sodium sulfide is an inhibitor of most sulfide ores. Due to the natural floatability of molybdenite, sodium sulfide cannot inhibit it. Using this, sodium sulfide can be used to suppress other sulfide ores when flotation molybdenite. At the same time, sodium sulfide is also the vulcanizing agent of non-ferrous oxide ore and the reagent-removal agent of sulfide ore mixed concentrate.
