In the field of mineral processing, effective pyrite suppression is crucial for improving the quality of concentrate from sulfide ores of non-ferrous metals. Traditionally, lime has been widely used as a pyrite depressant, but its high alkalinity can have adverse environmental effects. Therefore, developing a low-alkalinity, highly efficient, and environmentally friendly pyrite depressant has become a research hotspot.
D421B is a novel pyrite depressant specifically designed to meet the demands of modern mineral processing. Its main components include humic acid, sodium fulvate, glucose, and cellulose, which can effectively depress the floatability of pyrite under low alkalinity conditions.
Advantages of D421B:
High Efficiency: D421B forms a hydrophilic film on the surface of pyrite, hindering the adsorption of collectors, thereby reducing the floatability of pyrite and enabling effective separation from other valuable minerals.
Environmental Characteristics: Compared to traditional high-alkalinity depressants, D421B works effectively under low alkalinity conditions, reducing alkaline pollution to the environment and aligning with the requirements of green mining.
Wide Applicability: D421B is suitable for the flotation of various polymetallic sulfide ores, including copper, lead, and zinc, offering broad application prospects.
Method of Use:
Solution Preparation: Prepare a 1%-2% solution of D421B.
Addition Order: In the flotation process, add the D421B solution before the collector and frother.
Dosage Control: The recommended dosage is 50-600 grams per ton of ore, depending on the nature of the ore.
Packaging and Storage:
Packaging Specifications: Available in 25 kg/bag, 50 kg/bag, and 1000 kg/bag to meet different production needs.
Storage Conditions: Store in a cool, ventilated place, avoiding contact with strong oxidizers, reducers, or open flames.
Safety and Environmental Considerations:
Operational Safety: Avoid generating dust or aerosols. Operators should wear appropriate protective equipment to prevent skin and eye contact.
Environmental Protection: Avoid direct discharge into water bodies. Residual waste after use should be treated in accordance with environmental regulations.
Conclusion:
D421B, as a next-generation pyrite depressant, provides an ideal solution for the mineral processing industry with its high efficiency, environmental friendliness, and wide applicability. Its excellent performance under low alkalinity conditions not only improves flotation efficiency but also reduces environmental impact, aligning with the concept of sustainable development in modern mining.
