The laboratory is composed of :
- Jaw crusher (Dragon Babitless)
- Disk pulverizer (Fritsch)
- Agate crusher ((Tema industrie/Siebtechnik) fine granulometry for geochemical and X-ray diffraction applications
- Sieving columns (40 μm-2 mm grain size separation)
- Gemini shaking table (separation of light and heavy minerals)
- Laboratory oven for drying samples
