Summary. Antimony has a range of industrial uses in batteries, chemicals, ceramics and glass but by far the most important is in fire retardants. The economically most important ore mineral and principal source for the production of antimony is stibnite. Majority of antimony-bearing ore deposits are associated with the subduction-related ...Web

Human Exposure. In the United States, antimony (III) trioxide (Sb 2 O 3) is the most commercially significant form of processed antimony. In nature, Sb 2 O 3 exists in minerals such as valentinite and senarmontite ( ATSDR 2017; Roper et al. 2012 ). Antimony is found in nature in these and other mineral species, often in association with arsenic ...Web
Antimony is a silvery-white metal that is found in the earth's crust. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide. Little antimony is currently mined in the United States. It is brought into this country from other countries for processing. However, there are companies in …Web

In the process of electrolytic refining, the required antimony content of lead anode plate is approximately 0.4–0.7 wt%. When antimony content of lead anode plate is more than 1.2 wt%, antimony firmly adheres to the residual lead anode plate during the refining process, which leads to difficulty in cleaning.Web

We study the evaporation of antimony trioxide from an antimony-rich slag by bubbling nitrogen gas through a submerged top lance at 1000–1300 °C. Experiments are carried out with 300 g slag at gas flow rates of 20–60 l/h with the lance height of 1.5 and 10 mm. Slag samples are taken and analyzed to identify changes in the antimony trioxide ...Web
