Sodium sulfide is a chemical compound known for its multiple industrial applications, primarily in the realm of metallurgy and the production of chemicals. It is a yellow to red solid or solution that serves as a powerful reducing agent, facilitating the removal of oxygen from various metal ores during ore processing, thereby aiding in the extraction of metals like copper, lead, and zinc. Sodium sulfide also plays a role in the leather industry for hair removal during leather processing and in the textile industry for dyeing and desulfurization. Additionally, it is used in wastewater treatment as a precipitating agent for heavy metals and in the production of various organic chemicals. Its versatility as a reducing and sulfur-bearing agent makes sodium sulfide crucial in multiple industrial processes.

Lithopone is a white, inorganic pigment composed of a mixture of barium sulfate (BaSO4) and zinc sulfide (ZnS). It is widely used in the production of paints, coatings, and printing inks due to its exceptional opacity and brightness. Lithopone enhances the covering power of these products, making it especially valuable in applications where whiteness and opacity are critical, such as in the manufacturing of high-quality paints and paper. It also contributes to corrosion resistance and durability in coatings. Despite its historical use, its production has declined in recent years due to environmental concerns related to the presence of barium compounds, with many industries opting for alternative white pigments like titanium dioxide. Nonetheless, lithopone's unique properties continue to make it relevant in certain niche applications within the paint and coatings industry.

Calcium Polysulfide Solution is used mainly as a fungicide and fertilizer for the agriculture industry, to control wide range of fungal and other plant diseases in orchards, field crops and horticulture crops; it can also be used in various treatment systems as a metal precipitating agent. Calcium Polysulfide Solution effectively stabilizes and reduces soluble metals. Sales Specifications Appearance: Clear, to red orange liquid Assay:24.0-29.0% Odor:Slight H2S odor Density:1.25-1.29 @ 25�°C Treatment Notes Arsenic: Acid medium only forms various arsenic sulfides; pH>7; arsenic-sulfur compound are insoluble Lead: Wide Range (pH: 4-9); forms lead sulfide Copper: Close to neutral (Optimal pH: 5â??7); forms copper sulfide Zinc: Wide range (pH: 4-9); forms Zinc sulfide Cadmium: Wide range (pH: 4-9); forms cadmium sulfide Molybdenum: Wide range (pH: 4-9); forms molybdenum sulfide Uranium:Wide range (pH: 4-9); forms uranium sulfide Cyanide: Chemical Conversion produces Thiocyanate* *Thiocyanate can be bio-treated, or it can be treated with lime, producing calcium carbonate, gypsum and ammonia. Chromium (Cr VI) can be treated with calcium polysulfide, and the Cr(VI) is reduced to Cr (III), which is then precipitated as chromium hydroxide. While the list above indicates effective treatment may be obtained with system pH near 4.0, TKI has found that product is most stable in systems with pH greater than 5.0, to avoid potential generation of H2S.
