In essence, it involves the selective dissolution of valuable minerals, where the ore, concentrate, or matte is brought into contact with an active chemical solution known as a leach solution. Currently, the hydrometallurgical processes have a great number of applications, not only in the mining sector-in particular, for the recovery of precious metals-but also in the environmental sector, for the recovery of toxic metals from wastes of various types, and their reuse as valuable metals, after purification. Therefore, there is an increasing need to develop novel solutions, to implement environmentally sustainable practices in the recovery of these valuable and precious metals, with particular reference to critical metals; those included in materials that are indispensable to modern life and for which an exponential increase in consumption is already a reality, or will be in a short-term perspective. For publication in this Special Issue, consideration has been given to articles that contribute to the optimization of the kinetic conditions of innovative hydrometallurgical processes-economic and of low environmental impact-applied to the recovery of valuable and critical metals. 606 $aResearch & information: general$2bicssc 610 $aAl master alloys 610 $aAl-Ni alloys 610 $aalumina silica mass ratio 610 $aaluminothermic reactions 610 $aarsenic 610 $aarsenopyrite 610 $aascorbic acid 610 $acatalysis 610 $aChalcopyrite 610 $aclays 610 $acontaminated groundwater 610 $adesilication rate 610 $adry digestion 610 $aelectrowinning 610 $aELZPA ore deposit in Pakistan 610 $aeudialyte 610 $ageochemical characteristics 610 $agold 610 $agroundwater 610 $ahigh alumina fly ash 610 $ahydrometallurgical processes 610 $aHydrometallurgical processes 610 $aiodide 610 $aiodine 610 $akinetics 610 $aleaching 610 $aleaching kinetic 610 $alow-pressure leaching 610 $amining waste 610 $an/a 610 $ananoscale zero-valent iron 610 $aneural network 610 $anitric acid 610 $aoxygen 610 $apermeable reactive barrier 610 $aphysical-chemical activation 610 $apitchblende 610 $aprecipitation 610 $apyrite 610 $arare earth elements 610 $areaction rate 610 $areducing harmful emissions 610 $arefractory gold concentrate 610 $aresources depletion 610 $ashrinking core model 610 $athiosulfate oxidation 610 $athiosulphate leaching 610 $aU neutral leaching 610 $auranium 610 $awaste printed circuit board 610 $awastewater 610 $azero-valent iron 615 7$aResearch & information: general 700 $aUbaldini$b Stefano$4edt$01323480 702 $aUbaldini$b Stefano$4oth 906 $aBOOK 912 $a9910557691203321 996 $aLeaching Kinetics of Valuable Metals$93035605 997 $aUNINA
