3. What is iMineWa? intelligent MineWater managememt • iMineWa aims to improve current mine water management technologies by • Improving existing technologiese.g. • Internet of mine water • Technological age of mining • Implementing existing technologies e.g. • Electrocoagulation • Integrated Membrane technologies • Researching new technologiese.g. • Valorisation of mine water • New materials • New sensors

4. Main Goals • Enhance the technology age of mining • Bring mine water management to next stage • Instead of purifying a waste produce a resource • Getting rid of old habits (e.g. liming) • Enable the mining industry to produce at lower costs and environmentally friendly • Contribute to valorisation of mine water • Understand the hydrodynamics of flooded mines

7. Main Contents • Extract valuables in the mine water • convert them into commodities using • available and to be developed concepts and techniques • Use smart technology to manage mine water • underground • during transportation • in the winning process • Improve tracer techniques • understand the hydrodynamics of mine water • Improve sensor technology for mine water winning • Use of geothermal energy in the mine water

8. Main Stages • Identify gaps in current and past mine water technology • Identify techniques that can be used to extract (semi-)metals from liquid solutions • Improve mine water tracer techniques • Use various elements of existing technology to extract (semi-)metals from mine water in the lab and the pilot scale • Implement technique into an operating or abandoned mine in Finland • Improve nano-technology as a means to extract (semi-)metals from enriched water • Use biotechnology to concentrate the valuables in the mine water • Identify the potential of geothermally using the mine water within the winning process • Develop improved sensor technologies to control, fine-tune and communicate the winning process

9. Main Tasks • Providing a technological concept for managing mine water • “smart technology” • Installing a pilot plant • winning of valuables in polluted mine water • Co-operation with international and national partners • Dissemination of knowledge • short courses • conferences • Spreading of results • conferences • magazines relevant for the mining industry • SCI listed journals

10. Path Forward • Fill the gaps in current mine water management • From “mine water treatment” to “mine water winning” • Lets start a paradigm shiftor even • Let’s initiate a paradigm change • Together!
