Hematite Crusher
Introduction to Hematite: Market Prospects and Applications
Hematite, the most important iron ore mineral, accounts for approximately 70% of global iron production. With its high iron content (up to 70%) and excellent metallurgical properties, hematite remains crucial for steel production worldwide. The global iron ore market is projected to reach $373.69 billion by 2027, growing at a CAGR of 4.9% (Grand View Research).
Key Applications of Hematite:
- Steel Production: Primary raw material for blast furnaces
- Pigments: Natural red pigment in paints and cosmetics
- Radiation Shielding: Used in medical and nuclear applications
- Jewelry: Polished as “black diamond” gemstones
Hematite Mining and Processing Workflow
Hematite Mining Process
Exploration and Geological Survey
Geologists use magnetic surveys, drilling, and remote sensing to identify hematite deposits. Core samples are analyzed for Fe content and impurities.
Open-Pit Mining Operations
- Drilling: Rotary drills create blast holes (10-15m depth)
- Blasting: Controlled explosions fragment the ore
- Loading: Excavators load hematite onto haul trucks
Underground Mining (for deep deposits)
- Room-and-pillar method: For flat-lying deposits
- Sublevel caving: For steeply dipping orebodies
Hematite Processing Workflow
Primary Crushing Stage
Large hematite chunks (≤1500mm) are reduced to 200-300mm using Liming’s C6X Jaw Crusher, featuring:
- Optimized crushing chamber geometry
- Integrated motor base for vibration reduction
- 15-20% higher capacity than conventional crushers
Secondary Crushing
The material is further reduced to 30-50mm using Liming’s HST Single-Cylinder Hydraulic Cone Crusher, which offers:
- Laminated crushing principle
- Automatic control system
- Hydraulic clearing for jam protection
Grinding and Beneficiation
- Ball milling: Reduces particles to 0.074mm
- Magnetic separation: Recovers hematite from gangue
- Flotation: For fine particle concentration
Pelletizing (Optional)
- Mixing with binders
- Forming into 9-16mm pellets
- Induration (hardening) at 1300°C
