In this work, we investigated in situ isotopic compositions of antimony (Sb) minerals from two substages of the ore deposits near Pezinok (Slovakia). The δ123Sb values of the primary Sb minerals range from −0.4 and +0.8‰ and increase progressively along the precipitation sequence. In the substage II, the early-formed gudmundite …

This study aimed to introduce a comprehensive process for separating and recovering antimony from a complex stibnite concentrate. Antimony is first leached through a chlorination–oxidation procedure to obtain SbCl 3 solution. Antimony is then recovered in the forms of cubic crystal Sb 2 O 3 (99.9%), high-purity cathode antimony (99.98%), …

The most common antimony ore mineral is stibnite (Sb2 S3 ), but more than 100 other minerals also contain antimony. The presence of antimony in surface waters and groundwaters results primarily from rock weathering, soil runoff, and anthropogenic sources. Global emissions of antimony to the atmosphere average 6,100 metric tons per year.
