Many mineral components are observed in the refractory gold ore, including quartz (SiO 2), muscovite (KAl 2 Si 3 AlO 10 (OH) 2), pyrite (FeS 2), and arsenopyrite (FeAsS). Antimony is present mainly in the form of stibnite (Sb 2 S 3). All reagents were of analytical grade. The purity of the oxygen used during the pressure oxidation process ...

A Review on Pyrometallurgical Extraction of Antimony from …

Antimony is classified as a critical/strategic metal. Its primary production is predominated by China via pyrometallurgical routes such as volatilization roasting—reduction smelting or direct reduction smelting. The performance of most of the pyro-processes is very sensitive to concentrate type and grade. Therefore, technology …

Treatment of antimonial gold ores

Gold and antimony are associated in a number of gold ores with resulting complications in the gold extraction process. The principal mineralogical forms, in which gold occurs in these ores are metallic gold, free-milling, or associated with silicate gangue, as metallic gold associated with stibnite [Sb 2 S 3] will be seen from the processes used …

Antimony Metallurgy | SpringerLink

In 1986, China developed the chlorination–hydrolysis process that directly uses antimony sulfide ore to produce antimony trioxide (antimony white). The grade of antimony ores is usually 2–25%. Antimony minerals with industrial value include antimonite (Sb 2 S 3 ), senarmontite (Sb 2 O 3 ), cervantite (Sb 2 O 4 ), and cervanite …
