While ore contained many metals along with gold and silver, the environment in which these metals were found was carbonate, sulfated, silicated, and iron oxide-containing deposits that have undergone oxidation. In mineralogical studies, there were Fe oxy/oxyhydroxides, Pb/Zn carbonates, and jarosite-bearing structures such as beudantite, calcite, dolomite, clay, and quartz in the ore. The sample used in the experiments was d(80) = 29.6 & mu;m, and the test parameters were determined by examining the TG analysis made to the ore. Preroasting experiments were carried out at a roasting temperature range of 200-800 & DEG;C, during a roasting period of 10.0 min. Three different samples were characterized by TG for temperature changes, FT-IR for bond structures and permeability, SEM/EDX for visual inspection of structural changes, and XRD Rietveld's analysis for mineral % content differences. As a result of the cyanidation experiments carried out after the pretreatment, gold was recovered with 80-90% yields and silver with 40-48% yields, respectively.eninfo:eu-repo/semantics/closedAccessGossanOxidationRefractory oreRoastingPretreatmentCyanidationGold and silverArticle4051667167910.1007/s42461-023-00832-z2-s2.0-85168484960Q2WOS:001052033400001Q3
