Extracting antimony from high arsenic and gold
The antimony content in crude antimony was 94.31%. Although this process with short flow could eliminate the low-concentration SO 2 pollution, the antimony recovery rate and the antimony content in crude antimony were low. In the treatment of high arsenic and gold-containing stibnite concentrate, the problem of arsenic alkali residue …Web

The Legacy of Potential Environmental Soil Contamination in an Antimony
In the Valongo Belt, with an extension of about 90 km, located very close to Porto, northern Portugal, dozens of ore deposits of various metallic minerals and coal were exploited in the 19th and 20th centuries. One of the metals most intensely exploited was antimony, with or without associated gold mineralization. This research intends to verify the extent of the …Web

Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the residue, thereby realizing the value-added use of antimony and the recovery of gold. In this study, the thermodynamic conditions of antimony sulfide were analyzed …Web
