Bauxite Stone Crusher in the UK and Bauxite Beneficiation & Refining
Bauxite Stone Crusher in the UK
While the UK doesn’t have significant bauxite deposits (the primary ore of aluminum), crushers may be used for imported bauxite processing or recycling applications:
1. Crusher Types: Jaw crushers, cone crushers, and impact crushers can be used to reduce bauxite particle size
2. Applications:
– Preparing bauxite for alumina refining
– Processing recycled aluminum-containing materials
– Construction applications (where bauxite is used as an aggregate)
Bauxite Beneficiation Process

Bauxite beneficiation typically involves:
1. Washing: Removal of clay and silica
2. Screening: Size classification
3. Magnetic Separation: For iron removal
4. Flotation: For silica reduction
Bayer Process for Alumina Refining
The standard refining process includes:
1. Digestion: Crushed bauxite mixed with hot sodium hydroxide solution
2. Clarification: Separation of insoluble impurities (red mud)
3. Precipitation: Aluminum hydroxide crystals formed from cooled solution
4. Calcination: Heating to produce alumina (Al₂O₃)
UK Considerations
In the UK context:
- Most primary aluminum production relies on imported alumina or aluminum
- Recycling plays a significant role in UK aluminum supply chains
- Specialized crushing equipment may be used in secondary aluminum production facilities
