In 2011, the European Union elaborated a list of critical raw materials (CRMs), taking the economic and strategic importance for the European economy and the supply risk. Although focused mainly on the energy sector, the USA, Canada, and other countries took recently similar steps. Despite the great inertia characterising the mineral raw materials sector, some steps towards the Industry 4.0 paradigm can be envisaged. Significant challenges to the mining sector are the appropriate process design using the best available technologies; the increase in energy efficiency; the responsible use of water and handling of mining wastes; the social acceptance of the activity; and the digitalisation challenge. This book aims to propose strategies that can help face those challenges, especially in increasing energy efficiency in comminution operations. 606 $aHistory of engineering and technology$2bicssc 606 $aMining technology and engineering$2bicssc 606 $aTechnology: general issues$2bicssc 610 $aball mill 610 $aball mills 610 $abond work index 610 $aBond work index 610 $acomminution 610 $acritical metals 610 $acritical raw materials 610 $aelectrofragmentation 610 $aenergy efficiency 610 $agrindability 610 $agrinding kinetics 610 $agrinding media 610 $akinetic grinding 610 $aMarx generator 610 $ametallurgical coke 610 $amodeling 610 $an/a 610 $aparticle size distribution 610 $aPenouta Mine 610 $asimulation 610 $aSn-Ta-Nb 610 $aspecific grinding rate 610 $atungsten ore 610 $awork index 615 7$aHistory of engineering and technology 615 7$aMining technology and engineering 615 7$aTechnology: general issues 700 $aMene?ndez-Aguado$b Juan M$4edt$01326295 702 $aMene?ndez-Aguado$b Juan M$4oth 906 $aBOOK 912 $a9910566466803321 996 $aGrinding and Concentration Technology of Critical Metals$93037276 997 $aUNINA
