摘要: Environmental context Antimony enters the environment from tailings and mines but there are widely divergent statements about its mobility in environment. This work addresses question of Sb by a combination mineralogical geochemical studies. Abstract characterises two occurrences with an abundance supergene minerals brandholzite [Mg[Sb(OH)6]2·6H2O], klebelsbergite [Sb4O4(OH)2(SO4)] peretaite [CaSb4O4(OH)2(SO4)2·2H2O]. Brandholzite forms near-neutral waters, where stibnite (Sb2S3) decomposes presence abundant carbonates. The SbIII sulfates form acidic marcasite or pyrite (FeS2). These initial rapidly (brandholzite within weeks) supply into local waters. Calculation saturation indices underground water (present study) many waters discharged (data literature) show that (and related soluble minerals) undersaturated. Hence, if they do exist, should dissolve. Insoluble phases, such as tripuhyite (FeSbO4) grossly supersaturated, not (or very slowly). we conclude antimony observed studies is due to solubility minerals. immobility stated slow persistent formation insoluble tripuhyite. When kinetics these taken account, can be reconciled.
