Sodium di-sec-butyl Phosphorodithioate: A High-Performance Collector Driving Efficiency in Sulfide Ore Flotation

2026-01-21

In today’s increasingly competitive mining industry, improving recovery rate while maintaining concentrate grade has become a key concern for mining companies and procurement managers. Sodium di-sec-butyl phosphorodithioate is widely recognized as a highly efficient flotation collector for sulfide ores, especially in gold, silver, copper, lead, and zinc beneficiation. With its stable chemical properties, excellent selectivity, and low foaming characteristics, Sodium di-sec-butyl phosphorodithioate continues to be a preferred reagent for complex ore flotation circuits worldwide.

As a professional flotation reagent supplier, we provide high-quality Sodium di-sec-butyl phosphorodithioate with consistent performance, stable batches, and reliable logistics, ensuring smooth production for mining operations.

What Is Sodium di-sec-butyl Phosphorodithioate?

Sodium di-sec-butyl phosphorodithioate, also known as Natrium-O,O-di-sec-butyldithiophosphat or O,O-di-sec-butyl dithiophosphate, appears as a yellow to dark brown aqueous solution with no irritating odor. It exhibits stable chemical properties and strong adsorption capability on metal sulfide mineral surfaces.


In flotation systems, Sodium di-sec-butyl phosphorodithioate reacts selectively with valuable sulfide minerals, enabling them to attach to air bubbles and separate efficiently from gangue minerals. This makes Sodium di-sec-butyl phosphorodithioate an essential reagent in modern mineral processing plants.

Key Performance Advantages of Sodium di-sec-butyl Phosphorodithioate

1. High Collection Power for Sulfide Minerals

Sodium di-sec-butyl phosphorodithioate shows excellent collecting performance for gold-bearing sulfides, silver ores, copper sulfide, zinc sulfide, and lead sulfide minerals. Compared to conventional collectors, Sodium di-sec-butyl phosphorodithioate provides faster kinetics and higher recovery.


2. Outstanding Selectivity in Alkaline Circuits

In alkaline flotation systems, Natrium-O,O-di-sec-butyldithiophosphat has very weak collecting ability for pyrite, allowing selective recovery of target minerals. This selectivity makes O,O-di-sec-butyl dithiophosphate ideal for complex polymetallic ores where separation precision is critical.


3. Low Foaming, Stable Operation

Unlike some xanthate collectors, Sodium di-sec-butyl phosphorodithioate produces minimal froth. This allows operators to control the flotation process more easily and combine Sodium di-sec-butyl phosphorodithioate with professional frothers for stable and efficient separation.


4. Expanded Application Range

Under specific conditions, O,O-di-sec-butyl dithiophosphate also demonstrates collecting capability for certain heavy metal oxide ores, expanding its application beyond traditional sulfide flotation.

Main Applications of Sodium di-sec-butyl Phosphorodithioate

● Metal Sulfide Ore Flotation

Sodium di-sec-butyl phosphorodithioate is widely used in copper, lead, and zinc sulfide flotation. Its selectivity and strength improve recovery while maintaining concentrate quality. Many mines rely on Natrium-O,O-di-sec-butyldithiophosphat to stabilize their flotation performance.


● Gold and Silver Associated Ore Flotation

For gold and silver ores associated with sulfides, Sodium di-sec-butyl phosphorodithioate offers excellent recovery performance. Using O,O-di-sec-butyl dithiophosphate helps maximize precious metal recovery and significantly increases plant profitability.


● Nickel and Molybdenum Flotation

Sodium di-sec-butyl phosphorodithioate also acts as an auxiliary collector for difficult-to-float minerals such as nickel and molybdenum. In fine particle flotation, Natrium-O,O-di-sec-butyldithiophosphat delivers stable and predictable results.


● Complex Polymetallic Ore Processing

When processing complex ores with multiple valuable metals, O,O-di-sec-butyl dithiophosphate improves selectivity and simplifies flotation flowsheets. Many concentrators choose Sodium di-sec-butyl phosphorodithioate to optimize concentrate grade and reduce reagent consumption.
