The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony ore. The antimony in this study occurs as the mineral stibnite (Sb2S3) in association with small amounts of pyrite, arsenopyrite, galena and lead sulfantimonides.
The main purpose of this study is to characterize and separate antimony from a stibnite concentrate through a low-temperature sulfur-fixing smelting process.
A new process for one-step extraction of antimony in low temperature from stibnite concentrate by reductive sulfur-fixation smelting in sodium molten salt, using iron oxide as sulfur-fixing agent, was presented.
In the present study, a process for the separation and recovery of antimony from a stibnite flotation concentrate by chlorination leaching, purification, and electrowinning was introduced.
At present, flotation is the main beneficiation method for stibnite. Gravity separation is mainly used for the beneficiation of antimony oxide ore and the separation of coarse stibnite. Therefore, the beneficiation process of single antimony sulfide ore includes single flotation process and gravity separation-flotation combined process.
