Ammonium Dibutyl Dithiophosphate (CAS 1070-03-7) is the ammonium salt of dibutyl dithiophosphoric acid, a 95% active liquid reagent used as a selective collector in froth flotation for copper, lead, zinc, gold and silver sulfide ores. It is specifically formulated to act as a selective collector for precious and base metal sulfide minerals, enhancing recovery rates in complex circuits.

This reagent is typically available as a 95% active powder or an aqueous solution, offering excellent solubility and rapid dispersion in flotation cells. Its chemical structure provides superior selectivity for copper, lead, and zinc sulfides, while minimizing the collection of undesired iron-bearing gangue.

The product is valued for its stable performance across various pH levels, making it a versatile choice for multi-stage mineral processing. It is often combined with xanthates or other collectors to optimize the hydrophobicity of mineral surfaces and maximize the grade of the final concentrate.
