Stibnite - an overview | ScienceDirect Topics

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 ...
