Exploration, Sampling and Sample Analysis

read more »

The RE-ACTIVATE consortium covers all aspects of geological exploration, including geophysical methods (GPR, gravimetric-, electromagnetic-, electrical-, seismic surveys), borehole geophysics, surveying and aerial image and satellite-based remote sensing. Samples can be taken for a plethora of different analytical methods. For example mineralogical analysis (SEM-MLA, SIMS, XRD, Raman Spectroscopy etc.) and geochemical analysis (ICP-MS, AAS, XRF etc.). Furthermore, automated drillcore analysis will be available soon (for more information see ANCORELOG).

Exploration, sampling and sample analysis is compliant to CRIRSCO standards. If you are looking for a specific method, please do not hesitate to contact us.

Code-compliant secondary resource estimation analog to international standards (e.g. JORC, NI43-101, SAMREC, UNFC)

read more »

Estimations of secondary resources and reserves, i.e. extractive wastes, carried out by competent persons, analog to JORC, NI43-101, SAMREC, PERC or UNFC codes. Moreover, reassessments of old mine sites for updated resource estimates.

Due diligence & economic feasibility assessment for re-activation of former mine sites

Calculations determining the economic feasibility of possible mine operations.

Hydrometallurgical flow sheet development and optimization of tailings and mine waste processing (e.g. heap-leaching)

read more »

The best possible way of extracting valuable elements from extractive wastes or ores with complex mineralogy can be engineered by partners of the RE-ACTIVATE consortium.

For example, a leaching optimization procedure is currently used and further developed for the artic environment in the EIT RawMaterials funded project SO4Control (Scale-up of Solution for Mining Water Sulfate Control with Side-product Recovery).

Environmental Impact Assessment

Evaluation of the environmental impact of mining waste and monitoring of geological, geochemical, hydrological and geotechnical parameters in accordance with the “EU Directive on the management of waste from extractive industries" - Directive 2006/21/EC.

Tailings monitoring and risk evaluation

Utilization of geodetic, hydrologic/piezometric, geotechnical and microseismic parameters.

A tailings monitoring technology for mechanical and geochemical parameters of mine tailings is developed during the EIT RawMaterials funded project STINGS (Supervision of Tailings by an Integrated Novel Approach to combine Ground-based- and Spaceborne Sensordata), in which multiple RE-ACTIVATE partners are involved. Through the integration of near-surface and satellite-surveillance systems, an early warning system will be engineered, leading to an optimization of tailings risk management and safety standards. In addition, existing monitoring systems (e.g. DMT’s SAFEGUARD) are further developed in the RFCS funded project i²MON (Integrated Impact Monitoring), leading to a better procedure of monitoring active and inactive tailings.

Classification and sorting of radionuclide-bearing phosphogypsum tailings material

The EIT RawMaterials funded project raPHOSafe (Classification and Sorting of Radium-rich Phosphogypsum Tailings) resulted in the development of a conveyor belt radiological measurement facility for automated classification and sorting of naturally occurring radioactive material (NORM) bearing phosphogypsum (PG) tailing material. This patented approach can be implemented at various PG tailing sites.

Specialized services for securing underground mine infrastructure for further re-activation

Automated multi-sensor shaft inspection services, also for flooded mine sites, developed during the EIT RM funded Project iDeepMon (Intelligent Deep Mine Shaft Monitoring) and the RFCS funded project STAMS (Stability Assessment and Monitoring of Flooded Shafts).

 

Another specialized service is the extraction of geothermal energy from mine water.
