    The aqueous speciation and mineralogy of antimony (Sb) in waters and tailings at Beaver Brook antimony deposit have been analyzed to understand Sb mobility during the initial stages of stibnite (Sb2S3) weathering in a nearsurface environment. Dissolution of stibnite in oxidizing conditions releases Sb in drainage water and Sb is incorporated into the mineral structures of several secondary ...

The most important naturally occurring forms of antimony (Sb) are the ore mineral stibnite (Sb 2 S 3) and its principal weathering product antimony trioxide (Sb 2 O 3).Moreover, most Sb is released into the environment as Sb 2 O 3 from manufacturing, formulations, processing, and the use and disposal of Sb products. In this study, birnessite (δMnO 2) was employed to promote Sb 2 O ...
