    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,

    Stibnite: The mineral stibnite information and pictures

    Stibnite is named after the latin stibium, which is the old name of the element antimony (Sb). Stibnite was and continues to be the primary ore of antimony. Stibnite forms some of the most outstanding natural crystals that exist, in way of sharpness, luster, and size.It can form in groups of huge metallic lustered crystals that are elegantly crafted and exceptionally shiny.

    Stibnite - Wikipedia

    Stibnite, sometimes called antimonite, is a sulfide mineral with the formula Sb 2 S 3.This soft grey material crystallizes in an orthorhombic space group. It is the most important source for the metalloid antimony. The name is from the Greek στίβι stibi through the Latin stibium as the old name for the mineral and the element antimony.

    Antimony sulfide contained in an antimony sulfide bearing ore, such as stibnite, is converted to high purity antimony trichloride by reacting the antimony sulfide bearing ore with a source of chlorine to form high purity antimony trichloride and sulfur or hydrogen sulfide as separable by-products. The high purity antimony trichloride may be hydrolyzed to form high purity antimony

    THE STIBNITE GOLD PROJECT

    A CN regeneration plant was considered, but due to the characteristics of the Stibnite ore and process flowsheet, it would not result in a significant reduction in NaCN consumption, and therefore was not included. However, NaCN solutions used in the ore processing plant will be neutralized before tailings are discharged from the process plant.
