Antimony - Minerals Education Coalition

One use of antimony, which is declining, is to make type metal for printing newspapers and magazines. Antimony is one of very few substances (bismuth and water are two others) which expand when it cools and freezes. Antimony-bearing type metal thus fills every corner of a mold used to prepare sharp type for printing.

Antimony trioxide - Wikipedia

Antimony(III) oxide is the inorganic compound with the formula Sb 2 O 3.It is the most important commercial compound of antimony.It is found in nature as the minerals valentinite and senarmontite. Like most polymeric oxides, Sb 2 O 3 dissolves in aqueous solutions with hydrolysis.A mixed arsenic-antimony oxide occurs in nature as the very rare mineral stibioclaudetite.

Clean antimony production from stibnite concentrate with goethite ...

In view of the issues of low efficiency and environmental pollution existing in current antimony production, this work proposes an innovative and cleaner process to extract antimony from stibnite concentrate and co-treat goethite residues. The mechanisms of antimony extraction and zinc, iron, sulfur conservation was thermodynamically and experimentally investigated.

Antimony trioxide - Wikipedia

As of 2010, antimony (III) oxide was produced at four sites in EU27. It is produced via two routes, re-volatilizing of crude antimony (III) oxide and by oxidation of antimony metal. Oxidation of antimony metal dominates in Europe. Several processes for the production of crude antimony (III) oxide or metallic antimony from material.

Antimony Recovery from End-of-Life Products and Industrial Process ...

Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from its use as flame retardant in plastics, coatings, and electronics ...
