Chemical Description 

  • Aerofloat 404, chemically known as Sodium Diisobutyl Dithiophosphate, is a specialized flotation reagent used predominantly in the mining industry. This slightly yellow to brown liquid is highly effective in the selective flotation of sulfide minerals, including copper, lead, zinc, and nickel ores.
  • Its unique chemical properties enable it to act as a strong collector and frother, enhancing the separation process of valuable minerals from waste rock. Aerofloat 404's effectiveness in low concentration makes it a cost-effective solution for ore processing operations.
  • Aerofloat 404's molecular structure allows for a strong interaction with sulfide minerals, leading to enhanced selectivity in the flotation process. This selectivity minimizes the collection of non-target minerals, thus improving the grade of the concentrate.
  • Combining Aerofloat 404 with other flotation agents or technologies can result in synergistic effects, leading to improved recovery rates and operational efficiencies.
  • The compound works by modifying the surface properties of the target mineral particles, making them more hydrophobic and thus more likely to attach to air bubbles and rise to the surface in a flotation cell. This process significantly increases the efficiency of mineral recovery, contributing to higher yields in metal extraction processes.
  • In addition to its primary use in mineral flotation, Aerofloat 404 may find applications in wastewater treatment within the mining sector, aiding in the removal of heavy metals and other contaminants from water streams.
  • Aerofloat 404 is valued for its ease of use, compatibility with other flotation agents, and its effectiveness in a wide range of pH levels. This makes it a versatile agent for various mining operations and conditions.
  • Safety and handling precautions are essential when using Aerofloat 404 due to its chemical nature. Proper use and disposal practices are necessary to minimize environmental impact and ensure the safety of workers.
  • Aerofloat 404 represents a key component in the advancement of mineral processing technology, offering efficient, cost-effective, and reliable results for the mining industry. Its role in optimizing ore processing operations underscores its significance in the global market for mining chemicals.
