Working Principle of Graphite Ore Processing Lines
1. Amorphous Graphite Ore:
Process: Includes coarse crushing, medium crushing, fine crushing, grinding, flotation, dehydration, drying, and classification.
Equipment: Utilizes jaw crushers for primary crushing, hydraulic cone crushers and hammer crushers for medium and fine crushing, ball mills for grinding, SF-type and XJK-type flotation machines, dehydration screens, centrifugal dehydrators, spiral classifiers, and dryers.
2. Crystal Graphite Ore:
Process: Involves simpler crushing due to medium to soft nature and grade (2% to 10%).
Crushing Options: Includes three-stage open circuit, two-stage open circuit, or single-stage crushing; some smaller mines process weathered ores directly in ball mills.
Flotation: Typically follows closed-circuit approach with multi-stage grinding and beneficiation, aiming for recovery rates around 80%.
3. Cryptocrystalline Graphite Ore:
Process: Uses flotation as the primary method due to favorable flotation performance of scale graphite.
Additional Methods: May involve electrical separation, gravity separation, and others to achieve effective separation and recovery.
