D421B is an innovative flotation depressant developed by Y&X Beijing Technology Co., Ltd., designed to selectively suppress serpentine, pyrite, and other carbonaceous gangue minerals.
This specialized reagent improves the flotation separation of valuable minerals, particularly in ores with high levels of interfering gangue, such as graphite, serpentine, and pyrite.
By enhancing flotation selectivity, D421B maximizes metal recovery and concentrate quality, making it an essential tool for modern mineral processing.
Effective Suppression of Carbonaceous Minerals
D421B efficiently suppresses the flotation of unwanted carbon minerals, such as serpentine and pyrite, by creating a hydrophilic layer on their surfaces, preventing their flotation and separation.
Improved Selectivity and Recovery
The reagent improves flotation selectivity by ensuring that only valuable sulfide minerals are floated, leading to better recovery rates and higher concentrate grades.
Optimized for Low-Alkalinity Conditions
D421B performs well under low pH conditions, which is common in flotation processes used for gold, copper, and lead-zinc ores, where carbonaceous gangue interference is a significant challenge.
Reduced Reagent Consumption
By reducing the flotation of gangue minerals, D421B helps optimize the use of collectors and frothers, contributing to lower overall reagent costs.
Appearance: Fine black-brown powder
Recommended Dosage: 50-1000 g/ton of ore, depending on ore type and flotation conditions
Solution Preparation: Dissolve in water to create a 2% concentration solution
Application: Add to flotation conditioning or flotation tanks; pre-mixing in a stirred buffer tank is recommended to avoid sedimentation.
Packaging Options:
25 kg woven bags
850 kg jumbo bags
Storage Guidelines:
Store in a dry, cool, well-ventilated area, away from direct sunlight, moisture, and extreme temperatures.
Shelf life: 36 months under proper storage conditions.
Safety:
D421B is non-hazardous when handled correctly. However, operators should wear gloves, goggles, and dust masks to minimize exposure to dust.
Always consult the Material Safety Data Sheet (MSDS) for detailed handling instructions.
Environmental Considerations:
The majority of the reagent binds to gangue and is effectively decomposed during subsequent metallurgical processes. Tailings should be managed to prevent potential environmental contamination.
D421B has been successfully tested and used in a variety of flotation operations:
Gold Mining:
Effective in suppressing pyrite in gold-copper flotation systems, ensuring better gold recovery.
Copper Mining:
Helps in the flotation of copper sulfide ores by minimizing carbonaceous gangue interference.
Polymetallic Ores:
Proven in the flotation of lead-zinc ores with high carbon content, improving concentrate quality and recovery rates.
D421B is a reliable, cost-effective flotation depressant that enhances the separation of valuable sulfide minerals by effectively controlling carbonaceous gangue.
Its high selectivity, ease of use, and environmental benefits make it an ideal choice for mining operations seeking to improve flotation performance, reduce reagent consumption, and achieve higher-grade concentrates.
