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 …
Effect of Arsenic, Antimony, and Bismuth in Co-processing …
Antimony had a similar effect to arsenic on the nickel extraction (Fig. 8), with a decrease in the rate and extent of nickel extraction as the antimony addition to the system increased (i.e. higher percentages of antimony sulphide in the concentrate mixture). Reduced leaching of aluminium from the solids and precipitation of aluminium …
