It wag thought that the methods could be compared beet by using them on antimony saanpleg of known strength. A standard solution of antimony wag accordingly made by slowly boiling about 10 grams of C. P. antimony powder with 500 cc. of concentrated hydrochloric acid and 50 cc. of a saturated solution of bromine in hydrochloric acid,
Like most mineral processing, antimony ore processing consists of ore crushing, grinding, classification (gravity separation and cyclones) and flotation. The feed ore typically contains stibnite along with other gangue minerals. In China, it is pyrite, quartz, calcite, barite, kaolin, and gypsum.
beneficiation methods for antimony oxide ore. In view of this goal, we present a brief overview of recent advances in antimony oxide ore beneficiation pro-cesses, based on a review of sorting methods used for antimony oxide ores, both nationally and internation-ally. This review provides critical information for
Introduction Antimony ore, primarily composed of stibnite (Sb2S3), is a valuable resource due to its wide applications in various industries. The enrichment of antimony ore to increase its quality ...
The extraction of antimony involves both underground and surface mining methods, depending on the ore deposit's characteristics. After extraction, the ore undergoes crushing and flotation processes to concentrate the antimony content. The concentrate then goes through a smelting process to produce antimony metal or antimony oxide.
In HCl solution, antimony is dissolved in the form of SbCl 3 by adding oxidizing agents such as Cl 2, FeCl 3, SbCl 5, or H 2 O 2 (Zhao, 1987). Methods for the recovery of antimony from the SbCl 3 leaching solution include hydrolysis, replacement, distillation, and electrowinning. Although the foregoing methods afford high antimony recoveries ...

Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature. Stibnite (Sb 2 S 3) is the predominant ore mineral of antimony. The most important use of antimony metal is as a hardener in lead for storage batteries.
antimony ores, the most common beneficiation method is flotation. Therefore, antimony ore consisting of stibnite mineral obtained from Tokat-Turkey region was used in this study.
