Mechanochemical Treatment in Metallurgy : An overview

This review paper deals with the application of mechanochemical treatment with the aim to recover metals from both primary and secondary resources. For primary resources, the focus is on minerals like chalcopyrite, tetrahedrite and scheelite i.e. minerals with high activation energies where leaching in autoclaves at high temperature is needed to have acceptable leaching kinetics. In these cases, a mechanochemical treatment might enable leaching to be performed under atmospheric pressures. For secondary resources, emphasis has been on recycling of elements regarded as critical by the EU due to limited availability or high risk of future supply within the union.Godkänd; 2016; 20160623 (andbra
