High-Stability Dithiophosphate 31 Collector for Tin & Lead Processing

Product Introduction

Dithiophosphate 31 is a composite flotation collector specifically designed for selective sulfide ore separation. Its key distinction lies in the addition of approximately 6% thiocarbanilide to a base of Aerofloat 25 . This formulation significantly enhances its selectivity, particularly for galena (lead sulfide) and other non-ferrous sulfide minerals .

Unlike single-component collectors,31 dithiophosphate leverages the synergistic effect between its components. The primary base provides collecting power, while the thiocarbanilide intensifies the selectivity for specific valuable minerals and further reduces the collection of unwanted gangue, such as pyrite . This makes it highly valuable in complex separation processes, like differential copper-lead-zinc flotation.

Due to the poor water solubility of thiocarbanilide,31 dithiophosphate is typically introduced directly into the grinding mill ,This practice ensures optimal dispersion and early contact with the mineral surfaces, maximizing its effectiveness and contributing to improved concentrate grades in selective flotation circuits.

Product Advantage

1. dithiophosphate 31 offers a unique advantage through its synergistic composite formulation. The addition of thiocarbanilide to its base creates a collector with enhanced selectivity, particularly for galena and copper sulfide minerals. This chemical synergy provides superior mineral discrimination compared to single-component collectors.

2.The reagent demonstrates exceptional performance in complex separations, especially in differential copper-lead-zinc flotation circuits. Its formulation significantly improves rejection of pyrite and other gangue minerals, leading to higher-grade concentrates and more efficient separation of challenging polymetallic ores.

3.A key operational benefit is its persistent collecting power when added directly to the grinding mill. This early contact ensures thorough coating of mineral surfaces while the poor water solubility of its components contributes to prolonged action throughout the flotation circuit, making it particularly effective for coarse particle recovery and complex ore treatment.

Technical Parameters

Product Uses

Main Purpose: Dithiophosphate 31 can be used as a collector for the flotation of sphalerite, galena and silver ore, and also can be used for the flotation of gold oxide, lead oxide and silica malachite. It has foaming property, and its performance is better than Dithiophosphate 25.
