“…According to numerous studies, the concentration effect of the leaching chemicals is the most important factor in the ability of the hydrometallurgical method to recover metals from waste or ore. Additionally, other parameters in which this method is generally examined are leaching time, leaching temperature, and solid-liquid separation (Havlik and Friedrich, 2004;Onol and Saridede, 2013;Alkan et al, 2023). The experiments on the effects of the acetic acid concentration were carried out at 60℃, with a 10% solidto-liquid ratio, for 1 h, and at acid concentrations of 0.125, 0.25, 0.5, 0.75, and 1.0M (Fig.…”

“…In this study, metal recoveries increased up to 1 M concentration. Alkan et al (2023) studied Pb/Zn metal extraction and recovery by the leaching of ammonium acetate (AmAc) from zinc filter cakes (ZFCs). As the temperature increased over time, the recovery efficiency of both metals increased.…”

“…In particular, recycling processes have many advantages. Some of these advantages are reducing the environmental impact of harmful components in waste (Kaya et al, 2020), recycling valuable ingredients such as zinc (Alkan et al, 2023), and reducing the need for the landfill processing of fine-sized waste (Mikula et al, 2022;Yoğurtcuoğlu, 2023a).…”

“…As a result of leaching, a zinc recovery rate of 87.67% was achieved (Onukwuli and Nnanwube, 2022). The powerful acids mentioned above have drawbacks as well, such as their potential to easily evaporate, high consumption rates, and difficulties in recycling, while they dissolve several contaminants during the leaching process (Alkan et al, 2023).…”

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.

The purpose of this work is to obtain the optimum conditions for leaching the zinc contained in an industrial lead smelting slag. In this type of slag, zinc oxide, sulfide, and ferrite are contained. Zinc extraction from these compounds consists of using a single aqueous medium, where oxidant alkaline leaching with NaOH and NaClO was used. The parameters evaluated during the experiment were as follows: percentage of solids, NaOH/NaClO ratio, and temperature. The maximum amount of recovered Zn obtained during the leaching was 58%. This percentage was achieved by using the following optimal conditions: temperature of 60 °C, 0.22 of NaOH/NaClO ratio, 10% of solids, and a reaction time of 40 min. The calculated values of activation energy confirmed that the rate-limiting step of the reaction using the decreasing particle model is diffusion. The maximum percentage of zinc obtained could only have been achieved if the zinc oxide and part of the zinc sulfide (both present in almost equal proportions in the sample) were leached into the alkaline aqueous medium in the presence of NaClO.
