Activator D2 is a specialized chelating reagent for the flotation of oxidized minerals. Its key active component is 2,5-dimercapto-1,3,4-thiadiazole (DMTD), which can form stable complexes on the surface of oxidized minerals and improve their floatability.
Activator D2 is particularly suitable for oxidized copper minerals such as malachite and azurite. It can be added directly to the flotation circuit without requiring conventional pre-sulfidization in suitable applications. When used together with conventional collectors such as xanthate, it helps improve mineral surface hydrophobicity and supports the recovery of oxidized copper minerals.
The product is supplied in liquid form, making it convenient to feed and control during mineral processing. It can also be evaluated for selected oxidized lead, bismuth, tungsten, and tin ores.
Oxidized minerals often have different surface properties from sulfide minerals, making them difficult to recover with conventional flotation reagents. Activator D2 reacts with the mineral surface and forms a stable, water-insoluble chelate.
This surface modification can help:
Improve the floatability of oxidized copper minerals
Increase the attachment between mineral particles and air bubbles
Accelerate flotation kinetics
Support the use of conventional xanthate collectors
Simplify the reagent scheme by reducing the need for pre-sulfidization in suitable circuits
The final flotation performance depends on ore mineralogy, oxidation degree, pulp pH, water quality, particle size, reagent dosage, and flotation equipment.
Activator D2 is designed for oxidized copper minerals, especially malachite-type ores. It can be evaluated when conventional sulfidization methods provide insufficient flotation performance.
The liquid form can be added directly according to the plant’s dosing procedure. This makes the product convenient to control and suitable for continuous mineral processing operations.
For its stated application, the product specification indicates a dosage of approximately 1/5 to 1/3 of sodium sulfide. The actual dosage should always be confirmed through laboratory testing and plant trials.
Activator D2 can help accelerate flotation kinetics and improve the response of oxidized minerals in the flotation circuit. This may help reduce processing stages and improve overall process control.
When suitable ore conditions are present, Activator D2 can support the comprehensive recovery of associated metals such as gold and silver during oxidized ore processing.

Activator D2 can be evaluated in the flotation of:
Malachite and other oxidized copper minerals
Azurite and copper oxide ores
Oxidized lead minerals
Selected bismuth oxide ores
Tungsten oxide minerals
Tin oxide minerals

The product is especially suitable for low-grade or highly oxidized copper ores where conventional flotation methods may require additional activation or sulfidization steps.
Activator D2 mainly improves the surface properties and floatability of oxidized minerals. It is not a replacement for all collectors or frothers in a flotation circuit.
Depending on the ore and process design, it may be used together with:
The reagent combination, dosage, addition sequence, and conditioning time should be selected according to the characteristics of the ore. Activator D2, sodium sulfide, xanthate, and other collectors have different chemical functions and should not be treated as interchangeable products.
Activator D2 can be added in its original liquid form according to the plant’s reagent dosing system. Before use, the following factors should be evaluated:
Oxidation degree of the ore
Copper or lead mineral type
Pulp pH and water chemistry
Required conditioning time
Collector compatibility
Flotation kinetics and concentrate quality
Dewatering performance of concentrate and tailings
The reference dosage of 1/5–1/3 of sodium sulfide is not a universal replacement ratio. A dosage test should be completed before full-scale application.
Activator D2 is available in 200kg plastic drums. Buyers should confirm packaging, transportation, unloading, and storage requirements before ordering.
The product should be stored and handled according to the supplier’s safety documentation, site chemical management procedures, and applicable local regulations.
