Description

Ammonium O,o-Diphenyl Dithiophosphate is an organophosphorus compound widely utilized as a high-performance collector and flotation agent in mineral processing. Its primary value lies in its exceptional selectivity and efficacy in separating sulfide ores, particularly for copper, lead, and zinc, enhancing metal recovery rates and process economics. This chemical is essential for mining operations, metallurgical plants, and research institutions focused on extractive metallurgy and froth flotation technology.

Application

• Primary collector for the froth flotation of sulfide ores, including chalcopyrite, galena, and sphalerite.
• Used in the selective separation and concentration of copper, lead, and zinc minerals from ore.
• Acts as a flotation reagent to improve the recovery and grade of precious metals in complex ores.
• Employed as a corrosion inhibitor or an intermediate in the synthesis of specialized lubricant additives.
• Applied in research and development for novel extractive metallurgy processes and reagent formulations.
• Potential use as a ligand or precursor in coordination chemistry and catalyst systems.
