Chemical Description

  • Sodium Isopropyl Dithiophosphate (SIPD), a compound with the formula C3H7Na2O2PS2, is a versatile and efficient chemical agent primarily utilized in the mining industry for the flotation of metallic sulfide ores. Its ability to act as a collector for copper, lead, zinc, and other valuable metals enhances the selective separation of minerals during the flotation process. This not only increases the yield and quality of extracted metals but also improves the efficiency and sustainability of mining operations.
  • The compound manifests as a light yellow to amber liquid, characterized by its high solubility in water, which facilitates its application in aqueous systems. With a density of approximately 1.2 g/cm³ and a purity level of over 90%, SIPD meets the stringent requirements set forth for mining and industrial applications.
  • Beyond its primary use in mineral flotation, Sodium Isopropyl Dithiophosphate finds relevance in wastewater treatment processes. Its properties enable the precipitation and removal of heavy metals from wastewater, contributing to environmental protection efforts and compliance with regulatory standards for water quality.
  • Additionally, in the realm of chemical manufacturing, SIPD serves as a precursor or an intermediate in the synthesis of other chemical compounds, highlighting its versatility and importance in industrial chemical processes.
  • Packaged in 200 kg drums, 1100 kg IBC totes, or bulk ISO tanks, Sodium Isopropyl Dithiophosphate is prepared for safe and efficient transport and use across various industries. This packaging flexibility ensures that the product can be delivered in quantities that meet the diverse needs of its users, from small-scale operations to large industrial processes.
  • SIPD's role in enhancing the efficiency of mineral processing, coupled with its applications in wastewater treatment and chemical synthesis, underscores its significance as a key chemical agent. Its development and use are aligned with industry trends toward more sustainable and environmentally friendly practices, making it a valuable asset in the chemical and mining sectors.
