(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?”.

Book of abstracts now available

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.
