Study Notes
Introduction to Crushing
- Crushing is the first step in processing ore from the mine.
- Crushing is a part of comminution.
- Comminution is the process of progressively reducing the particle size of an ore stream.
Introduction to Comminution
- Comminution is necessary to liberate valuable minerals from gangue material.
- Comminution increases the surface area of valuable minerals for chemical reactions.
- Blasting in the mine can be viewed as the first stage of comminution.
- Crushing further reduces the size of run-of-mine (ROM) ore.
- Grinding follows crushing and aims to separate valuable minerals from gangue.
- Crushing uses compression against a rigid surface, while grinding involves abrasion and impact.
