Feldspar Crusher
1. Introduction to Feldspar: Market Value and Industrial Applications
Feldspar, the most abundant mineral group in Earth’s crust, constitutes about 60% of terrestrial rocks. As a crucial industrial mineral, global feldspar market size is projected to reach USD 1.2 billion by 2028 (Grand View Research), driven by growing demand in:
- Ceramics Industry: 50% of feldspar production is used in ceramic manufacturing
- Glass Production: Acts as flux to reduce melting temperature
- Fillers: Used in paints, plastics and rubber industries
2. Feldspar Mining and Processing Workflow
2.1 Feldspar Mining Techniques
Modern feldspar extraction involves:
- Open-pit mining: For near-surface deposits (most common method)
- Underground mining: For deep-seated pegmatite veins
- Selective mining: Hand sorting for high-purity deposits
2.2 Feldspar Processing Stages
The complete beneficiation process includes:
- Primary crushing: Using Liming’s C6X Jaw Crusher to reduce 1m lumps to 200mm
- Secondary crushing: Liming’s HST Cone Crusher further reduces to 50mm
- Grinding: Ball mills achieve 200 mesh fineness
- Magnetic separation: Removes iron-bearing minerals
- Flotation: Separates feldspar from quartz
