separation of lead from crude antimony by pyrorefining
Nov 28, 2016 While societies from thousands of years ago used it in the form of stibnite for decoration, in modern times it is used to make semiconductor devices, batteries, low-friction metals, cable sheathing and flame-proofing materials, paint, ceramic enamels, glass and pottery. The traditional method of producing antimony metal is through heat smelting. Oct 31, 2019 Despite its low crustal abundance, antimony is a common constituent of many rocks and minerals, just not in concentrations suitable for extraction as ore. The most common antimony ore mineral is stibnite (Sb 2 S 3), but more than 250other minerals also contain antimony (Boyle and Jonasson, 1984 Anderson, 2012).
