Sodium Hydrosulfide 70% (NaHS 70%)

Sodium Hydrosulfide 70% (NaHS 70%) | Bulk Supplier & Manufacturer

As a leading global manufacturer, we expertly produce and supply high-potency Sodium Hydrosulfide 70% (NaHS Flake 70%) for demanding industrial processes. Consequently, our controlled synthesis in solid flake form ensures a product with superior handling stability and precise sulfide content. Therefore, critical industries from mining to chemical manufacturing depend on our reliable supply for its powerful reducing and sulfidizing capabilities.

Mining & Mineral Processing Applications

Primarily, our Sodium Hydrosulfide 70% serves as an essential sulfidizing agent and depressant in the flotation of oxide and mixed oxide-sulfide ores. Specifically, it effectively sulfidizes oxidized copper, lead, and zinc mineral surfaces, enabling their recovery with standard sulfide collectors. Moreover, it acts as a selective depressant for zinc sulfides in copper-lead-zinc separation circuits. As a result, mining operations globally rely on our high-purity NaHS to significantly improve metal recovery from complex or low-grade ores.

Chemical Manufacturing & Sulfur Source

Furthermore, in Chemical Synthesis and Pulp & Paper Production, our Sodium Hydrosulfide 70% Flake is a key reagent and sulfur donor. Importantly, it is used in the manufacture of specialty chemicals, including sulfur dyes, thiourea, and other organosulfur compounds. Subsequently, in the kraft pulping process, it is employed to supplement sulfide losses, enhancing delignification and pulp yield. Additionally, its strong reducing properties make it valuable in wastewater treatment for precipitating heavy metals as insoluble sulfides.

Leather Tanning & Textile Processing

Simultaneously, for Leather Tanning and Textile Manufacturing, our NaHS 70% Flake plays a critical role. For instance, in the leather industry, it is used for unhairing hides and as a reducing agent in sulfide-based depilatory processes. Likewise, in textile production, it serves as a reducing agent in sulfur dyeing and printing processes, ensuring vibrant and consistent colors. Thus, manufacturers integrate our consistent-quality product to achieve efficient processing and high-quality finished materials.

Handling, Stability & Quality Assurance

We prioritize the Safety and Stability of our solid Sodium Hydrosulfide 70% Flake, which offers significant advantages over liquid sodium hydrosulfide solutions. Our flake form minimizes hydrolysis and degradation during storage and transport, providing a longer shelf life and more predictable performance. Hence, clients receive a safer, more concentrated, and easier-to-dose Sodium Hydrosulfide 70% Flake that meets strict specifications for purity and minimal iron and heavy metal content.

Global Logistics & Technical Support

We facilitate secure global export and bulk supply with a robust, experienced logistics network. Presently, we deliver Sodium Hydrosulfide 70% Flake in sealed, moisture-resistant packaging such as steel drums or specialized bulk bags. Therefore, partnering with us ensures a dependable supply of this critical processing chemical, backed by expert technical application support.
