Sep 1, 2013 · Sphalerite has historically been the main and only target for In recovery among deposits enriched in Zn (Cook et al., 2011b). At present, there are only few available data regarding trace elements such as In and Au in Pb–Sb-bearing minerals from tin-polymetallic deposits. An enrichment of In in jamesonite, and potentially other sulfosalts, as ...

Aug 20, 2024 · The sphalerite leaching process involved the formation of zinc chloride ion complexes and evolution H 2 S gas. An unexpected finding is the presence of lead sulfate in the leach residue, which may be attributed to sulfide oxidation to sulfate species. The Avrami kinetic model provided an excellent fit with the sphalerite dissolution data in ...

Feb 1, 2024 · Both unsupervised and supervised multivariate and ML methods are used to classify deposit types based on trace elements in sphalerite. The workflow for data preparation, transformation, deposit type classification, model construction, and prediction are shown in Fig. 3.For unsupervised multivariate and ML methods, the whole data set (4012 analyses for five …

Jun 1, 2024 · Sphalerite is a commonly occurring mineral in natural systems and a prominent indicator mineral used in resource exploration. Its chemistry and associated mineral assemblages are both controlled by the physicochemical conditions of the local environment, such as temperature and sulfur fugacity. Accordingly, the chemistry of sphalerite and the ...

Apr 1, 2018 · Sphalerite in sample WSH-65 shows colloform and banded texture with grain size of ∼0.1 mm; in contrast, sphalerite in sample WSH-95 shows well-defined and various grain sizes, which systematically decrease (lower to upper) from ca. 1 cm to ca. 0.1 cm, indicating the deposition rate increased upwards. The two hand specimens display different ...
