Rock saws, grinding and polishing machines are used to produce (polished) thin sections of rock.
Equipment
- Rock saws for cutting through up to 50 cm blocks of rock
- Seeders for sizing rocks
- Various Bühler grinding and polishing machines
- Frantz magnetic separator
- Wilfley vibrating table
- Well diamond wire saw 3500
- Bühler micro saw
- Retsch vibrating disk mill
- Retsch micromill (with agate, tungsten carbide and boron carbide insert)
- Micromill
Principle
After the sample is crushed with a jaw crusher, the crushed material can be separated by gravity separation in water (gold panning, Wilfley shaking table) or in heavy liquids. A further separation step can be carried out with a hand magnet or a Frantz magnetic separator.
