Around 30.000 children and adults celebrated the 4th edition of the European Minerals Day on 24-26 May 2013 at their next door quarrying or mining operations, to explore the fascinating world of minerals and discover how essential they are to our daily life. Overall, more than 170 events took place, organised by mineral raw materials producers and national geological surveys at around 113 sites – quarries, mines or plants - in 24 countries all over Europe, and beyond. Through guided visits, visitors got the opportunity to learn more about today's sustainable mining practices, from exploration, extraction, sorting and mineral beneficiation processes, as well as the wide range of end-use applications, as well as good environmental practices. The event reports will be published on www.mineralsday.eu.
