Pilot site 1.1: Germany

Location: Research and Education Mine “Reiche Zeche” – Freiberg, Germany

Involved partners: TUB (lead), ICCS, LTU

Pilot Germany

Two Pilot Sites are situated at TU BAF: One is Reiche Zeche a former silver mine which is now used as research and education mine. The mine offers the proper infrastructure for the whole spectrum of underground mining research: extraction of ore (Biohydrometallurgy), ventilation, geophysical testing etc. The currently assigned mine field is approximately 12-14 km of mine workings. The main tasks here are:

– Deployment of Mine.io digital infrastructure and Edge systems in our research and educational mine Reiche Zeche

– Test bed for real time digital monitoring and cloud-based process control of the drilling rig and mine ventilation system

– Implementing a digital twin of the mine ventilation system

Pilot site 1.2: Germany

Location: Digital TSL-Smelter at the Institute of Nonferrous Metallurgy – Freiberg, Germany

Involved partners: TUB (lead), LTU, subcontractors (mecorad GmbH and Bundesanstalt für Materialforschung und -prüfung)

Pilot Germany

The second Pilot Site situated at TU BAF in Freiberg is a Top Submerged Lance (TSL) smelter which is common in the non-ferrous metallurgical industry. As part of the project, this key processing plant will be digitized by combining the existing infrastructure with novel sensors to create a new measurement-driven generation of digital twins. The aim is to demonstrate a beyond state-of-the-art sensor-based digitization technology for smelting at TRL6.

An advanced digital twin system will be developed using the plant ACT platform, incorporating advanced measurements and online process models using HSC-Sim software. To further enhance the capabilities of the digital twin system, advanced sensors will be integrated into the platform. These sensors will enable deeper analysis of fluid dynamics through acoustic measurements. Radar and LIBS measurements provide valuable insights into slag properties. The inclusion of off-gas measurements using FTIR methodology will allow for comprehensive assessment of process emissions. Additionally, monitoring the temperature and bath partial pressure of oxygen will facilitate optimal impurity removal and valuable metal recovery.

Location: Ore Processing Plants, KGHM Polska Miedź S.A. – Polkowice, Poland

Involved partners: KGHM (lead) Ł-ITR, Ł-EMAG, AGH, LTU

Pilot Poland

The main objective of this pilot project is to install and test the PIT System at KGHM Polska Miedź S.A., within selected flotation cells. The effectiveness of the system will be experimentally verified in the industrial environment of the flotation process. Throughout the pilot tests, a substantial dataset of froth images and froth samples will be collected for chemical and XRF analysis.

The collected data will enable the optimization of machine learning (ML) and artificial intelligence (AI) algorithms for accurately estimating the metal content based on froth image patterns. Additionally, the development and testing of AI algorithms and associated software for monitoring the flotation process will be conducted.

The resulting algorithms, modules, methods, processes, and procedures will be integrated within the components of the AI analytical system. This integration will enhance the overall monitoring capabilities of the system, improving its efficiency and effectiveness in overseeing the flotation process.

Pilot site 3.1: Greece

Location: Lavrion Ancient Silver Mines, Attica Region, Greece

Involved partners: AMDC (lead), ACC, HMU, USAL

Pilot Greece

The goal of this pilot project is to showcase a cutting-edge sensor-based digitization technology for on-site exploration and waste identification. This technology will be demonstrated at the TRL6 level, surpassing the current state-of-the-art. Additionally, a Risk Assessment methodology and an Environmental & Social Impact Assessment (ESIA) approach to guide us in selecting the most suitable remediation and metal extraction methods or technologies will be implemented.

As part of the project, we will not only focus on demonstrating the selected remediation methods or technologies but also investigate the possibility of coordinating these measures with the extraction and utilization of the waste material that is being removed. By doing so, it aims to maximize the benefits and minimize the environmental impact of the overall process.

Furthermore, the assessment of environmental and social impacts during the post-mining era will be prioritized, ensuring that project actions contribute to long-term sustainability and the well-being of the affected communities. This comprehensive approach will enable us to make informed decisions in choosing the appropriate remediation, metal extraction methods, and technologies.

Pilot site 3.2: Greece


Involved partners: AMDC (lead), WRPC, MUO, INE

Pilot Greece

The underground hazardous waste repository (Figures 2.7, 2.8) (UHWR) examined was constructed in 2009, within the borders of Lavrion Technological & Cultural Park (LTCP) at the city of Lavrion, Greece. The main goal was to be used as a storage unit for hosting various waste resulting from the remediation activities of the former metallurgical plant that existed on site. In addition to the storage of the waste, the site can also be used for several research operations.

The unique feature of the repository is that it has been constructed in low overburden especially for the purpose of waste storage and is also equipped with several technical barriers to safeguard the waste containment, unlike traditional deep repositories.

It was developed almost 40 m below ground level, following the principles of the room and pillar mining method. Thus, the rooms (corridors) with a width of 5.5 m and a height of approximately 6 m are developed, while the pillars of the host rock that remain in place are rectangular in shape, having a 7 m width. The total area of the repository is approximately 2200 m2, with an available free space of around 1800 m2.

Pilot Site 3.2 was selected for demonstration during the evolvement of the project and it is not described in the DoA or the GA. The Partners considered that it is an ideal site for implementing the Muon Technology (T3.1) targeting in the exploration stage.

Location: Pyhäsalmi Mine – North Ostrobothnia, Finland

Involved partners: UOULU

Pilot Finland

In this project, we will use two imaging techniques, electric resistivity imaging (ERI) and seismic imaging (SI), to study and understand the underground conditions of tailings embankments. We will focus on a specific area on the Western side of the tailings facility at Pyhäsalmi mine in Finland. By applying these technologies, we aim to create detailed maps and interpretations of the subsurface conditions in that area.

Pilot Germany

This pilot project aims to bring together the concepts of electric power and self-driving technology. It will showcase the process of transforming a vehicle from using a traditional gasoline engine to an electric drive system. The focus will be on developing the electric drive system that meets the required load specifications. Additionally, the project will demonstrate an automatic docking system using inductive loops.

Location: Malaposta open pit site – Urgeiriça mine, Portugal

Involved partners: INE (lead), MUO, WRCP

Pilot Portugal

This pilot project will focus on experimenting with the Muon telescope technology and its robotic deployment process in an open pit. The goal is to develop advanced autonomy features that can be integrated into a robot capable of exploring flooded mines. To validate these developments and take advantage of operational benefits, the initial field testing will be conducted at the Malaposta site. Once validated, the autonomy and robotic data integration into the Mine.io model will be further tested at the Urgeiriça mine in northern Portugal near Viseu. The main focus of this validation will be on assessing rock densities. To ensure the safety of personnel, underwater robotic assessment will be used to minimize risks. Additionally, efforts will be made to enhance the autonomy of the robotic system for operation in the challenging underwater mine environment
