Investigation of the characteristics of stibnite (Sb2S3) flotation
An example of this material is the tailings from the stibnite flotation process (Güven et al., 2012, Radková et al., 2020). In general, this type of tailings contains toxic elements such as remaining unrecovered antimony (Sb), arsenic (As), and iron (Fe) in sulfide mineral form and precious metals such as Au and Ag (Wu et al., 2019).

The hydrometallurgical approach utilizes the differential solubility of arsenic and antimony compounds to facilitate their separation. Utilizing the sulfur-affinity of arsenic and antimony, Na 2 S was employed as the leaching agent, by which 95 % of As and Sb can be decomposed as Na 3 SbS 3 and Na 3 AsS 3 (Gu et al., 2019). A subsequent ...

Low-Alkalinity flotation separation of antimony and arsenic …
Polyacrylamide is modified and innovatively used as an inhibitor of arsenite. Modified polyacrylamide can suppress the recovery rate of arsenite to less than 5%, while the recovery rate of stibnite is almost unaffected. Modified polyacrylamide is a naturally degradable, non-toxic, relatively inexpensive green agent, which has great potential application value in antimony …
