Kaolin Processing and Flotation Solutions
Kaolin Beneficiation
Kaolin deposits can contain iron- and titanium-bearing minerals that negatively affect the brightness or "whiteness" required for many downstream applications. Depending on the characteristics of the deposit, flotation or selective flocculation can be used to remove these color-causing impurities.
Other contaminants, including carbonates and sand, may be removed through appropriate sizing and washing.
The appropriate beneficiation strategy depends on the mineralogy of the deposit, required product specifications, and individual plant operating conditions.
Kaolin Processing Challenges
Producing high-quality kaolin can involve challenges throughout the mineral processing operation, including:
- Removal of iron- and titanium-bearing impurities
- Achieving required brightness and whiteness
- Maintaining flotation selectivity
- Managing slurry rheology
- Transporting kaolin through pipelines
- Managing recycled process water
- Maintaining consistent product quality
Because every kaolin deposit has different mineralogical characteristics, reagent selection and process conditions must be tailored to the individual ore and desired product specifications.
Arkema's Kaolin Processing Solutions
Arkema develops customized reagent programs to help kaolin producers improve impurity removal, brightness, rheology, and overall processing performance.
Our kaolin processing solutions include:
- Cationic and anionic collectors
- Frothers
- Flotation reagents
- Flocculants
- Dispersants
- Rheology modifiers
- Customized reagent programs
