Umwelt- und Ingenieurtechnik GmbH Dresden (UIT), Germany, is specialized in Mineral Resources, Environmental Monitoring and Water Technology, focusing on in-situ recovery (ISR) of technology metals. Main activities include consulting, full-scale engineering, manufacture and practical implementation of technical systems, and turn-key plant construction in the above business areas. UIT operates two technical centers for lab and pilot scale testing: water technology and hydrometallurgy. Complementarily, UIT develops and actively applies dedicated software tools for computer simulations in (3D) hydrology, geochemistry/reactive-transport, chemical processing, etc. – mainly regarding mining and environmental/remediation applications. Most important, UIT is actively involved in industrial in-situ mining operations covering exploration (e.g. borehole logging) and prospect development, planning (hydrology/leaching chemistry), engineering (recovery and processing), post-mining remediation, and management.
Column Leach Test Facility (saturated flot):is designed according to international standards, operating a 3-channel system either in horizontal or vertical flow.
oreLOG (Advanced Borehole Logging Tool):is for multi-functional geophysical logging and applicable to most technology metal deposits.
3D Geological and Hydrological Modeling:Geological/Geochemical/Hydrological interpretation and 3D modeling (GOCAD/Micromine/WellCAD/FEFLOW/PhreeqC and in-house software aquaC, TRN and KiLea) including structural mapping and interpretation, geochemical and petrological modelling, interpretation and visualization of mineralization patterns and target generation.
Extractive (Hydro-)Metallurgy and Mineral Processing:UIT provides expert know-how on the relevant technologies and licensing steps required for extracting technology metals (REE, PGE, etc.) and for separation of associated naturally occurring material (NORM) and processing of radioactive elements such as uranium (U), thorium (Th), and their decay products.
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 are in accordance to realistic ISR wellfield conditions (aquifer temperature and pressure, pore volume exchange rate) and are monitored by real-time data logging/control. Drill cores and bulk samples can be tested and analyzed for ISR feasibility and performance.
oreLOG (Advanced Borehole Logging Tool) for multi-functional geophysical logging: applicable to most technology metal deposits:
• Improve accuracy/precision of ore grade logging
• Integrate lithological logging (host rock lithology, geophysical/hydrological parameters)
• Integrate mineral logging (most reactive minerals)
• Measure borehole geometry (size, inclination)
-> Improved database for ISR planning
-> All by ONE tool (economic effect)
Geological/Geochemical/Hydrological interpretation and 3D modeling (GOCAD/Micromine/WellCAD/FEFLOW/PhreeqC and in-house software aquaC, TRN and KiLea) including structural mapping and interpretation, geochemical and petrological modelling, interpretation and visualization of mineralization patterns and target generation.
Reactive transport modeling for ISR and in groundwater incl. post-mining remediation (natural attenuation, enhanced natural attenuation, in-situ remediation)

Geophysical borehole logging constrains petrophysical parameters of the ore body and the host rock – instead of biased drill core interpretation. However, often the parameters measured by common standard commercial geophysical probes provide insufficient constraints on ore-body properties. Such properties are often ambiguous, i.e. constraints are weak. Well measured, petrophysical parameters provide an important link to seismic survey data as they allow to constrain interval velocity models, and therefore to generate 3D models of the ore body.
UIT‘s geophysical borehole logging tool oreLOG provides petrophysical key-constraints allowing you to make the next key exploration decision. It utilizes a pulsed neutron generator to enable precise measurements of geochemistry and mineralogy of the ore body and host rock. The oreLOG logging system captures both mineralogy and ore grade; it measures porosity, deduced permeability, hole inclination, and further parameters with high accuracy.
