(1) Hand selection The hand selection process of antimony ore is carried out by utilizing the differences in color, luster and shape between antimony-containing mineral deposits and gangue in antimony ore. Although this method is primitive and labor-intensive, it still has special significance when used in antimony ore beneficiation.
