(Re)Mining Extractive Waste
A new business?
17-18 May 2022, Mechelen, Belgium
The 2-day symposium “(Re)Mining extractive waste, a new business?” gathers leading experts in the field of mining and/or remining of extractive waste, with a focus on the tailings that arise during the mining and processing of sulphidic ores. The latest evolutions in the field, novel concepts and business cases will be presented, including case studies from both historical and active mining sites.
Since the earliest days of the Industrial Revolution, the primary mining and metal processing industry has been landfilling and/or stockpiling vast quantities of waste. This waste type, termed “extractive waste”, is considered as one of the largest waste streams in Europe. Specific precautions need to be taken when dealing with sulphidic mine tailings, as upon oxidation of residual sulphides, acidic waters are generated. These can result in the release of residual heavy metals to surface and ground waters.
Especially in the case of historical mining sites, pre-dating the EU Extractive Waste Directive, this can cause problems, as these sites in general lack the required environmental protection. Given the ambition to move towards a more circular economy the question arises if the extractive waste problem cannot be transformed into a resource recovery opportunity. Put differently, can the (re)mining of extractive waste become a new business? That was also the question that was addressed in the a previous (on-line) “NEMO Lunch Event & Debate” (April 2021). During this gathering three experts – Christian Wimmer (EC DG Environment, Anders Sand (Boliden) and Dirk Musser (Cronimet) – shared their views on the barriers and opportunities for remining extractive waste. The five lessons learned from this event will form the backbone of the Symposium “(Re)Mining extractive waste, a new business?”.
Abstract Submission and Registration
The symposium gathers experts in the field of mining and/or remining of extractive waste. The target public comprises industry, academia, policy makers and civil society. Speakers will contribute to four sessions: mapping, resource estimation & geometallurgy; metal and mineral recovery; bulk mineral matrix valorisation; multi-criteria assessment, policy and Social License to Operate (SLO). Oral presentations/poster sessions are combined with workshops and roundtables on Life-Cycle Assessment (LCA) and SLO aspects of (re)mining extractive waste. There will be ample networking opportunities. We especially invite speakers presenting successful case-studies of metal/mineral recovery from tailings.
Registration for the conference is now open. You can register here

Arne has received a master and doctoral degree in Materials Engineering from KU Leuven. During these studies, his interest in metallurgy was transformed into a love for the valorization of industrial by-products. The PhD, delivered in 2018, focused on the reaction mechanisms for alkali-activation of iron-rich slags that can be used as a sustainable cementitious binder. Since 2019, he is working at VITO to transform a wide variety of mineral residues in cement and concrete constituents. He manages the research in a few projects and tries to understand and communicate about how industrial residues can be used in construction materials.
ir Thomas Lapauw has obtained a master degree in materials science at KU Leuven in 2013. During his doctoral thesis, he studied intensively the synthesis of high temperature ceramics for nuclear applications. Since 2018, he is active at ResourceFull as CTO where he returned to room temperature chemistry to develop ecological-friendly building materials and enthusiastically committed himself to a more sustainable and circular construction world.
Prof. Dr.-Ing. Daniel Goldmann is the Chairman of the board of CUTEC Clausthal Research Center for Environmental Technologies; Director of the Institute of Mineral and Waste Processing, Waste Disposal and Geomechanics; and Head of the Department of Mineral and Waste Processing at TU Clausthal.
His scientific focus is on flotation, mechanical and hydrometallurgical processing of complex, metal bearing waste streams and ores, esp. critical raw materials; recycling strategies for and in complex structures of advanced circular economy.
Anders Sand (D.Sc., Docent, QP) is a Research manager at Boliden Mines.
Anders Sand has about 15 years’ experience in senior academic and corporate positions in the mining industry, with the main field of expertise in mineral processing technology. At Boliden he has held positions as Process Manager, Manager of the Process Technology R&D Programme and currently as Research Manager.
He holds a D.Sc. degree in Chemical Engineering from Åbo Akademi University, Finland and is Docent in Mineral Processing at Luleå University of Technology, Sweden.
Francisco Veiga Simão
Francisco Veiga Simão is a Portuguese geoscientist with an entrepreneurial mind-set and a passion for circular economy. Holds a BSc in Geology and a MSc in Geosciences with specialisation in geological resources from the University of Coimbra (Portugal). During his graduate studies he also attended the University of Oviedo (Spain) and The University Centre in Svalbard (Norway). Currently works at Wienerberger NV (Belgium) as an Early Stage Researcher (ESR12) within the EU-H2020-MSCA-ITN-ETN-SULTAN project and is a PhD researcher at the Catholic University of Leuven (Belgium). His research is focused on the sustainable use of (cleaned) sulphidic mining waste in building ceramics. Helped to found and raise a Portuguese start-up company (Geonatour), which does geological consulting jobs and promotes geodiversity through a mobile application. Worked as an intern geologist in a Portuguese technology start-up company (Primelayer), where he did consultancy jobs on e-waste management. Was also a co-founder of an entrepreneurial project (WEEE-DO) aiming to maximise the efficiency of the collection, reuse, and recycling of electronic waste in Utrecht (The Netherlands). Recently, co-founded the Energy and Climate Forum (FEC), a Portuguese NGO focused on promoting and supporting climate resilient and sustainable projects around 9 Portuguese-speaking countries (Angola, Brazil, Cape Verde, Guinea-Bissau, Equatorial Guinea, Mozambique, Portugal, São Tomé and Príncipe, and East-Timor).

In addition, she has 4+ years of international experience in geometallurgical characterization of industrial and metallic minerals and critical raw materials in England and France (Portuguese and German deposits). She has taken the role of main research engineer in the recovery of critical minerals from old tailings dumps and from primary raw materials.
Ville Heikkinen is Research manager in Terrafame Sotkamo mine and holds an MSc in Physical chemistry, Graduated from University of Oulu, Finland. Ville has 18 years of experience in R&D and operations in hydrometallurgical industry. He has worked with the Terrafame process for 16 years involving positions in R&D, metals recovery and bioleaching.
Dr. Anne-Gwénaëlle Guezennec is an expert in biohydrometallurgy and more specifically in bioleaching process design. Her research work focuses on three main areas: the characterization of mass and energy transfer in bioleaching reactors and their influence on microorganisms activities; the design of innovative bioreactor; the adaptation of bioleaching processes to unconventional resources such as electronic wastes, complex mining wastes, lateritic resources. She has developed a novel and original research methodology relying on the association of innovative numerical modelling and multiscale experimental approaches to study the complex interactions occurring in a bioleaching reactor between the microbes and the G/L/S phases.
