Product Description
Depressant D471 is a specially formulated flotation reagent designed to effectively suppress clay minerals, such as montmorillonite and kaolinite, in various mineral processing applications. Suitable for weakly acidic to neutral pH environments, D471 works by reducing the interference of clay minerals, enhancing both concentrate grade and recovery rates. It also addresses the issue of fine tailings, enabling rapid settling in tailings water. When combined with water glass (sodium silicate), its performance improves significantly, making it an ideal choice for complex flotation systems.
Product Features
- Product Name: Depressant D471
- Appearance: White solid particles
- Dosage: Typically 100-500 g per ton of raw material
- Key Ingredients: Carboxymethyl starch, sodium hexametaphosphate
Usage and Application
Depressant D471 is primarily used in flotation processes to suppress clay minerals in a low-alkaline environment. Its unique composition allows it to be highly effective in separating valuable minerals from clay-heavy ores. Additionally, it enhances the clarity and rapid settling of tailings, making tailings management more efficient. For optimal performance, D471 can be used in a 1:1 to 3:1 ratio with water glass.
Packaging and Storage
- Packaging: Available in 25 kg and 50 kg bags
- Storage: Store in a cool, well-ventilated area away from strong oxidizers, reducers, and open flames.
Safety and Handling
To ensure safe handling of Depressant D471, avoid dust formation and minimize contact with skin and eyes. Operating personnel should wear protective clothing, gloves, and eye/face protection, following all operational guidelines closely.
Applications
- Clay Mineral Suppression: Designed for use in ores with high clay content, D471 effectively reduces the impact of montmorillonite and kaolinite on flotation performance, enhancing concentrate quality.
- Tailings Water Clarification: D471 promotes rapid settling of fine tailings particles, improving tailings water clarity and making it easier to manage.
- Optimized for Weakly Acidic to Neutral pH: The reagent performs optimally in low-alkaline flotation environments, maintaining efficiency without the need for additional alkali.
Summary
Depressant D471 is a versatile and powerful reagent for suppressing clay minerals in mineral processing, particularly beneficial in complex flotation systems. Its robust performance in enhancing concentrate quality, managing tailings water, and compatibility with other reagents, such as water glass, makes it an ideal choice for challenging clay-heavy ores.
