“…The most common enrichment method for these ores is the physicochemical (flotation) method (Yoğurtcuoğlu, 2023b) where the surface is sulfurized, and anionic collectors such as xanthates (Ahmed et al, 2021) are applied (Şentürk et al, 1993; Önal et al, 2005). There are also zinc recovery studies in which anionic and cationic collectors have been applied together for oxide and mixed-type ores (Hosseini and Forssberg, 2006;Hosseini and Forssberg, 2007;Hosseini and Taji, 2015;Magela et al, 2021;Henrique et al, 2022).…”

Non-sulfide lead flotation tailings draw attention in terms of their valuable contents. Dissolution studies have been carried out with strong inorganic acids, especially in ore form, but these acids have been unfavorable in removal in the context of metal recovery processes. Organic acids, on the other hand, are notable for their environmentally friendly properties and selective metal recovery opportunities. In this study, the effects of acetic acid on metal recovery from oxidized waste were investigated with different experimental parameters at a laboratory scale. Optimal conditions were determined depending on the increase in acetic acid concentration. At 0.75-1.0 M acid concentrations, 49-55% Pb and 49-54% Zn recovery efficiencies were obtained with grades of 7.0-7.2% and 19.5-19.7%, respectively. The recovery of Pb/Zn by the leaching process with acetic acid and the selective non-recovery of iron were also observed through characterization studies. With the Rietveld XRD method, an increase in iron minerals such as goethite and a decrease in smithsonite-hydrozincite minerals were determined. These changes were seen as a decrease in the contents of these minerals in SEM/EDX analysis and as a decrease in smithsonite mineral bond structures in the FT-IR analysis. This study showed that acetic acid has many advantages in the utilization of zinc-lead-containing oxide flotation tailings, which have high economic value, such as selective metal recovery, easy biodegradability, environmental friendliness, and non-corrosiveness.

Commercial strong anion exchange resins provided by Purolite, namely MTA4801PF, and MTA4601PFSO4, were utilized for extracting uranium from sulfate leach liquor. The study focused on investigating the kinetics, isotherms, and thermodynamics of the sorption process. Both resins demonstrated similar kinetics and isotherm performance, with sorption capacities of approximately 66 and 71 mg g−1 respectively. The sorption process was proven to be endothermic, feasible, and spontaneous, and U(VI) desorption of around 95% was achieved using 0.5 M sulfuric acid. Commercial resins showed excellent sorption performance when applied to sulfate leach liquor of Egyptian ores despite the complexity of the solution.
