D421B is a state-of-the-art flotation depressant developed by Y&X Beijing Technology Co., Ltd., designed to optimize the flotation performance of ores containing carbonaceous gangue.
This high-efficiency depressant is particularly effective in suppressing minerals like serpentine and pyrite, ensuring that valuable sulfide minerals are selectively recovered in flotation systems.
D421B is widely recognized for its ability to improve concentrate grades and recovery rates, making it a preferred solution for complex ore processing.
Selective Suppression of Carbonaceous Gangue
D421B effectively inhibits the flotation of carbonaceous minerals such as serpentine and pyrite, ensuring that only valuable sulfides are floated, leading to higher concentrate purity.
Improved Recovery and Concentrate Grade
By controlling gangue interference, D421B enhances the flotation selectivity of valuable minerals, improving both recovery rates and concentrate quality.
Suitable for Low-Alkalinity Systems
D421B performs well in flotation processes that require mild pH conditions, such as those used for gold, copper, and polymetallic ores. Its ability to operate effectively in low-alkalinity environments adds to its versatility.
Cost-Effective and Easy to Use
D421B helps reduce overall flotation reagent consumption by minimizing the need for excessive collectors and frothers, optimizing your operational costs. It is simple to use, requiring minimal adjustment to existing flotation circuits.
Appearance: Brown to black fine powder
Dosage Range: 50-1000 g/ton of ore, depending on ore characteristics
Solution Preparation: Prepare a solution with a concentration of less than 2%
Application: Add to flotation conditioning tanks or directly to flotation cells; pre-mixing in a stirred buffer tank is recommended to prevent sedimentation.
Packaging Options:
25 kg woven bags
850 kg bulk bags
Storage Instructions:
Store in a cool, dry, and well-ventilated area, away from direct sunlight, moisture, and extreme temperatures.
Shelf life: 36 months under proper storage conditions.
Safety Precautions:
D421B is considered non-hazardous, but operators should still wear gloves, goggles, and dust masks when handling the product to avoid skin and eye irritation.
Please consult the MSDS for comprehensive handling and safety instructions.
Environmental Impact:
The product binds with gangue during flotation and is decomposed during subsequent processing stages. Tailings disposal should be managed to avoid contamination of natural water systems.
D421B has been successfully applied across various flotation systems and has shown significant improvements:
Copper Ore Processing:
In copper flotation circuits with high levels of carbonaceous gangue, D421B has reduced gangue interference, leading to higher copper recovery and concentrate purity.
Gold Ore Flotation:
In gold flotation, D421B has minimized pyrite flotation, improving gold recovery while maintaining low pyrite content in the final concentrate.
Polymetallic Ores:
For lead-zinc ores, D421B has helped separate valuable sulfides from interfering carbonaceous minerals, resulting in cleaner concentrates.
D421B is a powerful, reliable flotation depressant that helps mining operations optimize the flotation of valuable metals by effectively managing carbonaceous gangue.
Its selective action, operational flexibility, and cost-effectiveness make it an essential tool for modern flotation plants looking to enhance performance and improve economic outcomes.
