A selective process for extracting antimony from refractory gold ore .

To avoid the adverse effects of antimony on the cyanide leaching process used for the recovery of gold from refractory gold ore, a cleaner production process was proposed that would selectively remove antimony as sodium pyroantimonate. The process included three steps: 1) leaching of antimony from the refractory gold.

ore processing - Midas Gold

10.1 PROCESS OVERVIEW. Ore processing for the Stibnite Gold Project is the separation of gold, silver and antimony from its host rock. The processing will result in production of an antimony concentrate and a gold- and silver-rich doré and barren tailings. The Project is expected to produce for sale approximately 4-5.

The extraction of Antimony from its ore - Levity

The following photographic documentation of the process of extracting antimony from its ore made by one of my French correspondents and one of his colleagues. He says:- "These pictures describe an experiment undertaken a few years ago related to the Dry path of antimony (or Stibnite Path) as followed by E. Canseliet.

Mineral Resource of the Month: Antimony | EARTH Magazine

No marketable antimony has been mined in the United States since 2001, when the Sunshine Silver Mine in Idaho, which produced antimony as a byproduct, closed. The U.S. relies heavily on imports from China, which dominates global mine production of antimony ores and concentrates and which restricts the amount of.

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

Abstract Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Anti- mony is produced from stibnite ore (Sb2O3) which is pro- cessed into antimony metal and antimony oxide (Sb2O3). The industrial importance of.

Antimony Mobilization through Two Contrasting Gold Ore .

Apr 22, 2009 . waters had low dissolved Sb (\0.1 mg/L). A second stage of gold mineralization at Reefton involved brecciation and cataclasis of quartz veins and wall rocks, with addition of stibnite (Sb2S3). Processing of this ore has resulted in higher dissolved Sb in mine waters (0.1–1 mg/L), even after water treatment.

US3174848A - Process for treating high antimonybearing gold ores .

An object of the present invention is to provide a process for treating high antimony bearing gold ores which results in a substantially increased gold recovery therefrom. In accordance with the invention, a roasting charge of gold ore concentrates containing 2% to 20% antimony is treated by the addition of 3 to 15% common.

Extraction of Antimony - Element Antimony, Sb, Metalloid

Antimony is extracted mainly from ores containing antimony trisulphide in the form of stibnite. . It is further suggested that it is inadvisable to extract antimony from rich ores by fusing the sulphide with iron on account of the high fusion temperature required; if this process is adopted a reducing atmosphere should be.

Draft Toxicological Profile for Antimony and Compounds

Most of the primary antimony generated in the United States was generated as antimony trioxide. Antimony trioxide is produced by oxidizing antimony sulfide ore or antimony metal in air at 600–800°C (Avento and Touval 1980). In 1987 and 1988, 18,758, and 18,226 metric tons of the oxide were produced, respectively.
