Mineral processing / hydrometallurgical test center


The column leach test facility (saturated flow) is designed according
to international standards, operating a 3-channel system either in
horizontal or vertical flow. Operational parameters in accordance to
realistic ISL wellfield conditions (aquifer temperature, pore volume
exchange rate) monitored by real-time data logging/control.

• Anaerobic column preparation (N2)
• 3-channel high-precision peristaltic feed pump
• 3-channel temperature control
• 3 parallel columns (horizontal or vertical)
• In-line measurement of pH, ORP, EC, (I), p
• Injection leachant reservoirs
• Leachate collectors for sampling
• DCLTF allows use of intact and undisturbed drill core samples and
various sizes (NQ, HQ, PQ)

Percolate column leach tests are performed under ambient physical
conditions in order to simulate heap leaching. Performance depends
on chemical parameters, unsaturated flow conditions and additional
parameters (e.g. particle size distribution, homogeneity, porosity).
Test results enable up-scaling of an ideal reactive transport model to
real-world scenarios.

• Crushing, grinding and sieving
• Sorting (magnetic separation, gravity separation, flotation)
• Solid-liquid separation
• Consulting, process optimization
• Mineral and chemical analyses incl. NORM by ore microscopy,
XRF and Raman
• Process design and basic engineering
• Heap leaching
• In-situ recovery
