Product Description: Sodium Dimethyl Dithiocarbamate is a highly versatile organic sulfur compound acclaimed for its broad-spectrum utility in multiple domains. It serves as a potent fungicide, pesticide, and an invaluable intermediate in the pharmaceutical synthesis of various drugs. Additionally, it finds extensive use in manufacturing other dithiocarbamates and rubber chemicals.

Key Features:

• Versatility: Widely utilized in agriculture, pharmaceuticals, and chemical synthesis for its multifaceted applications.

• Efficiency: Proven efficacy as a biocide for fungal control and as a pesticide to protect crops and other assets.

• Safety: Must be handled with care due to its inherent toxicity; proper safety measures are imperative.

Applications:

• Mining Flotation:

• SDMDTC excels as a collector in froth flotation, significantly enhancing the separation of valuable minerals from gangue. Its strong complexation abilities with metal ions make it ideal for selective ore flotation.

• Fly Ash Treatment:

• In coal combustion byproduct management, SDMDTC immobilizes heavy metals in fly ash, minimizing their environmental impact. This is especially beneficial when fly ash is repurposed in cement production or soil amendments.

• Heavy Metal Treatment:

• SDMDTC acts as a selective extractant for cobalt during the hydrometallurgical purification of zinc, aiding in the removal of cobalt impurities from zinc sulfate solutions. This selective complexation ensures higher purity zinc products and enables the recovery of cobalt as a valuable byproduct.

• The selective complexation of cobalt by SDMDTC allows for its separation from zinc, facilitating the purification process and enabling the recovery of cobalt as a valuable byproduct.

• SDMDTC's chelating properties allow it to form stable complexes with heavy metals, facilitating their removal from industrial wastewater and contaminated soils during environmental remediation.

• Cobalt Removal in Zinc Smelting (Hydrometallurgy):

• Agricultural Soil Treatment:

• SDMDTC is effective in remediating soils contaminated with heavy metals by forming complexes with the metals, thereby reducing their bioavailability and mobility.

• Industrial Wastewater Treatment:

• In industrial settings, SDMDTC is utilized to treat wastewater laden with heavy metals, ensuring compliance with stringent regulatory discharge standards.

Safety Information:

• Always wear appropriate personal protective equipment (PPE) when handling SDMDTC.

• Avoid inhalation, ingestion, and skin contact. Use in well-ventilated areas to mitigate exposure risks.

Storage Conditions:

• Ensure optimal preservation by storing in a cool, dry environment, shielded from heat sources and direct sunlight.

• Maintain the pristine quality of the product by keeping the container securely sealed.
