D421B is a high-performance flotation depressant developed by Y&X Beijing Technology Co., Ltd., specifically formulated to selectively suppress carbonaceous minerals such as serpentine and pyrite.
This depressant is designed to enhance the selectivity of flotation systems, improving the recovery of valuable metals from ores with high carbon content.
D421B offers significant advantages in maintaining flotation efficiency, improving concentrate grades, and reducing operational costs, especially in complex ore types.
Selective Carbon Suppression
D421B is effective in suppressing unwanted carbon minerals, such as serpentine and pyrite, by forming a hydrophilic barrier on their surfaces, thereby preventing their flotation.
Improved Recovery Rates
By enhancing the separation between valuable minerals and gangue, D421B helps increase metal recovery while reducing contamination from non-target minerals.
Flexible Application in Low pH Conditions
D421B works efficiently in flotation systems that require low pH conditions, such as those used for gold, copper, and lead-zinc ores with high carbon content.
Reduced Reagent Consumption
The depressant minimizes the need for excessive collectors and frothers, optimizing reagent usage and lowering operating costs.
Appearance: Brown to black fine powder
Recommended Dosage: 50-1000 g/ton of raw ore, adjusted according to ore type
Solution Concentration: Prepare a <3% solution in water
Application Points: Introduce into flotation conditioning or flotation cells; pre-mixing in a stirred buffer tank is recommended to avoid sedimentation.
Packaging:
25 kg bags
850 kg jumbo bags
Storage Requirements:
Store in a cool, dry place away from direct sunlight, moisture, and extreme temperatures.
Ensure proper inventory rotation using the first-in-first-out method.
Safety:
While D421B is non-toxic, it is recommended to handle the product using proper personal protective equipment such as gloves, goggles, and dust masks to avoid irritation or inhalation of dust.
Always refer to the Material Safety Data Sheet (MSDS) for detailed safety guidelines.
Environmental Impact:
The majority of D421B binds to the gangue during flotation, and its residues are typically decomposed during subsequent processing.
Ensure proper management of tailings to minimize environmental impact.
D421B has been successfully applied in a variety of flotation operations, including:
Copper Ores: Effective suppression of carbonaceous gangue in copper flotation systems, improving concentrate grade and metal recovery.
Gold Ores: Reduces pyrite flotation interference, ensuring better gold recovery rates in gold-copper flotation systems.
Lead-Zinc Ores: Efficient separation of sulfide minerals from carbonaceous gangue, resulting in purer concentrates and improved metal extraction.
D421B is a reliable and cost-effective depressant that addresses the challenges posed by carbonaceous gangue in flotation circuits.
It helps optimize flotation performance, enhance concentrate purity, and reduce overall reagent costs. With its proven performance in a variety of ores, D421B is an essential tool for mining operations seeking to maximize efficiency and profitability.
