The possibility of application of mechanochemistry in extractive metallurgy and material science is illustrated. Surface oxidation of mechanically activated sulphides, sorption properties of CaCO3 after mechanical activation, gold leaching from mechanochemically pretreated Cu-Pb-Zn complex concentrate and pilot plant tests of mechanochemical technology (process MELT) have been selected as examples of application of mechanochemistry in physical chemistry and extractive metallurgy. The mechanochemical reduction of Cu2S with the aim to prepare nanocrystalline copper can serve as an example of a novel process for preparation of advanced materials in materials science.
