Efficient Activator D2 for Oxidized Copper & Lead Ore Flotation.

Product Introduction

D2 Activator is a specialized chelating collector in mineral processing, primarilycomposed of 2,5-dimercapto-1,3,4-thiadiazole (DMTD) as its key active component . It serves as a highly effective activator for oxidized copper minerals  like malachite, significantly improving their floatability . This reagent can be applied directly to oxidized ores without pre-sulfidation, simplifying the flotation process.

The primary advantage of D2 lies in its ability to form stable complexes on the surface of oxidized copper minerals, enabling efficient recovery using conventional xanthate collectors . Field applications demonstrate that D2 can increase copper recovery by more than 10-20% compared to traditional sulfidation methods alone . It proves particularly valuable for processing low-grade, highly oxidized copper ores where conventional methods yield poor results.

Additionally, D2 shows effectiveness for various oxidized minerals including lead, bismuth, tungsten, and tin ores . Its usage helps accelerate flotation kinetics, reduce processing stages, and enhance overall metallurgical performance in complex ore treatment.

Product Advantage

The D2 Activator offers significant advantages in processing oxidized minerals, particularly for copper ores like malachite and azurite. Its key strength lies in forming stable, water-insoluble chelates on mineral surfaces, enabling effective flotation without requiring pre-sulfidation. This simplifies the process and enhances recovery where traditional methods often fail.

A major operational benefit is its ability to boost copper recovery by 10-20% compared to conventional sulfidation. It achieves this by accelerating flotation kinetics and improving mineral surface hydrophobicity when used with standard xanthate collectors. This makes it highly effective for low-grade and complex oxidized ores.

Furthermore, D2 demonstrates versatile application across various oxidized ores, including lead, zinc, and tungsten. Its use helps reduce reagent consumption, shorten processing stages, and lower overall costs, providing a robust solution for enhancing metallurgical performance in challenging flotation circuits.
