Antimony Production

Antimony ores are concentrated by flotation and gravity methods The element is extracted mostly by pyrometallurgical method which is precipitation of the fusion with iron Alternatively partially oxidized ores as well as for ores containing precious metals are subject of oxidizing roasting with sublimation

Effective stabilization of antimony in Waste

Recycling of iron-bearing waste for stabilizing antimony (Sb) in Waste-to-Energy (WtE) fly ash is a low-cost and sustainable approach In this work two laboratory iron–rich residuals (LIR–1 and LIR–2) were collected and their effectiveness for stabilizing Sb in WtE fly ash were evaluated by toxicity characteristic leaching procedure (TCLP) and continuous acid leaching tests The results

A correlation between sulfur and antimony grain boundary segregation has been observed on inter-granular surfaces of iron by Auger electron spectroscopy (AES) The slope of a plot of S/Sb indicated a ratio of two antimony atoms per sulfur atom arriving at the grain boundary while the ratio for the total S/Sb at the grain boundary was about 1 2

Notes-Antimony oxide is used as an opacifier in low fire glazes and porcelain enamel (mainly leadless but it has been replaced to an extent by titania) Antimony is easily reducible thus an oxidizing agent like potassium nitrate may be required to prevent it from going into solution and losing its opacifying power and affecting color
