Sodium Hydrosulfide Boosts Efficiency in Mining & Metallurgy — Richase Strengthens Core Chemical Supply
As global mineral development advances toward higher efficiency and environmental sustainability, Sodium Hydrosulfide (NaHS) has become an essential chemical in the mining and metallurgical industries. Leveraging years of experience, Richase continues to provide high-quality sodium hydrosulfide products to help mining clients optimize processes and increase recovery rates.
In hydrometallurgical processes, sodium hydrosulfide is primarily used as a metal sulfide precipitant. It selectively precipitates heavy metal ions such as copper, nickel, zinc, cobalt, and molybdenum from solution by forming insoluble sulfides (e.g., CuS, NiS), enabling efficient separation and valuable metal recovery.

For oxidized or refractory copper ores, sodium hydrosulfide functions as a flotation agent or activator, enhancing the hydrophobicity of mineral surfaces. This improves the flotation behavior and significantly increases the recovery and grade of copper concentrates.
In gold cyanidation leaching, sodium hydrosulfide is used to remove interfering metal ions such as copper that may consume cyanide. It also serves as a protective base, optimizing the leaching environment and ensuring effective gold recovery.
As a reliable supplier of mining chemicals worldwide, Richase continuously improves product quality and supply chain capabilities, delivering high-purity, highly reactive sodium hydrosulfide products to meet the diverse needs of mineral processing and metallurgical operations.
At Richase, we don't just supply high-quality grinding media; we provide data-driven recommendations. Our experts analyze your specific operation to recommend the most cost-effective grinding solution, ensuring you achieve the optimal balance between grinding efficiency, media consumption, and final recovery rates.
