Jan 01, 2016 · The rate of oxidation of stibnite is strongly dependent on pH with appreciable dissolution at pH 12, reducing to low levels at pH 10. Figure 52.1 shows Hedley and Tabachnick's (1958) results of the cyanidation of a synthetic ore containing 0.25% stibnite at pH values of 10, 11, and 12. At higher pH values, higher levels of antimony pentoxide have been observed on gold surfaces, which then

An antimony recovery process is disclosed in which antimony-containing material is leached in a solvent including elemental sulfur and a caustic to preferentially leach antimony. The antimony-containing leach liquor from the leaching step is separated from the insoluble residue by filtration, and the antimony compounds in the separated leach liquor are crystallized to separate the antimony

Feb 08, 2016 · Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from its use as flame retardant in plastics, coatings, and …
