Sodium di-sec-butyl phosphorodithioate | High-Performance Collector for Sulfide and Precious Metal Flotation

Sodium di-sec-butyl phosphorodithioate is a high-performance flotation collector extensively used in the beneficiation of gold ores and sulfide minerals containing silver, copper, and zinc. As a proven and widely adopted reagent, Sodium di-sec-butyl phosphorodithioate plays an essential role in improving flotation recovery, concentrate grade, and overall separation efficiency in mineral processing operations.

In flotation systems, Sodium di-sec-butyl phosphorodithioate reacts with the surface of valuable sulfide minerals through chemisorption. This interaction enhances mineral hydrophobicity, enabling gold- and base-metal-bearing particles to attach firmly to air bubbles. As a result, effective separation from gangue minerals is achieved, significantly increasing mineral enrichment efficiency.

A key advantage of Natrium-O,O-di-sec-butyldithiophosphat is its excellent selectivity. In alkaline flotation circuits, Natrium-O,O-di-sec-butyldithiophosphat exhibits very weak collecting power toward pyrite. This selective behavior makes it especially suitable for complex polymetallic ores, where selective recovery of gold, copper, silver, or zinc is required while suppressing pyrite flotation. The use of Natrium-O,O-di-sec-butyldithiophosphat therefore contributes to higher concentrate grades and reduced impurity content.

Another important feature of O,O-di-sec-butyl dithiophosphate is its low frothing property. During flotation, O,O-di-sec-butyl dithiophosphate primarily acts as a collector rather than a frother, preventing excessive foam formation. When used together with dedicated frothing agents, O,O-di-sec-butyl dithiophosphate helps maintain stable froth conditions, improving process controllability and flotation efficiency.

Under specific operational conditions, Sodium di-sec-butyl phosphorodithioate also demonstrates a certain collecting ability for heavy metal oxide ores. This expands the application range of Sodium di-sec-butyl phosphorodithioate, allowing mineral processing plants to handle partially oxidized ores more effectively and improving overall resource utilization.

Thanks to its strong collecting ability, excellent selectivity, and low frothing behavior, Natrium-O,O-di-sec-butyldithiophosphat is widely recognized as a reliable flotation reagent in the global mining industry. With proper dosage control and circuit optimization, O,O-di-sec-butyl dithiophosphate can help mining companies achieve higher recovery rates, improved concentrate quality, and stable flotation performance across various ore types.
