Product Description: Sodium Dimethyl Dithiocarbamate is a versatile organic sulfur compound with applications in various fields. It is used as a fungicide, pesticide, and in the pharmaceutical industry for the synthesis of various drugs. SDMDTC is also used as an intermediate in the production of other dithiocarbamates and rubber chemicals.

Key Features:

• Versatility: Utilized in agriculture, pharmaceuticals, and chemical synthesis.
• Efficiency: Effective as a biocide in controlling fungal growth and as a pesticide.
• Safety: Should be handled with care due to its potential toxicity.

Applications:

• Mining Flotation:

  • SDMDTC can be used as a collector in the froth flotation process to enhance the separation of valuable minerals from waste rock (gangue). Its ability to form complexes with metal ions can aid in the selective flotation of certain ores.

• Fly Ash Treatment:

  • In the context of coal combustion byproducts, SDMDTC can be utilized to immobilize heavy metals present in fly ash, reducing their mobility and potential environmental impact when the fly ash is used in various applications such as in cement production or as a soil amendment.

• Heavy Metal Treatment:

  • Due to its chelating properties, SDMDTC can form stable complexes with heavy metal ions, making it useful for the removal of heavy metals from industrial wastewater and contaminated soils in environmental remediation processes.
  • Cobalt Removal in Zinc Smelting (Hydrometallurgy):
    • In the hydrometallurgical purification of zinc, SDMDTC can be employed as a selective extractant for cobalt. This is particularly useful in the treatment of zinc sulfate solutions where cobalt impurities need to be removed to meet purity standards for zinc products.
    • 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.

• Agricultural Soil Treatment:

  • SDMDTC can be used to remediate soils contaminated with heavy metals by forming complexes with the metals, thereby reducing their bioavailability and mobility.

• Industrial Wastewater Treatment:

  • In industrial settings, SDMDTC can be applied to treat wastewater containing heavy metals, helping to meet regulatory discharge standard.

Safety Information:

• Wear appropriate personal protective equipment (PPE) when handling SDMDTC.
• To ensure personal safety, avoid inhalation, ingestion, and direct skin contact. Always use this product in a well-ventilated area to minimize risks.

Storage Conditions:

• Store this product in a cool, dry place, away from heat sources and direct sunlight to maintain its effectiveness and longevity.
• Keep the container tightly sealed at all times to preserve the product's integrity and quality.
