For some minerals, this induced mechanochemistry can enhance recovery in flotation [37]. However, in fine and ultrafine grinding for ore liberation, wet grinding dominates due to the greater efficiency, and because subsequent separation processes tend to require wet operation, making the advantages of dry milling in terms of water usage redundant.
