abstract: Laterite nickel ore is the main source of nickel, which is widely utilized through hydrometallurgical processes, one of which is Atmospheric Acid Leaching (AAL). The success of the AAL process is influenced by several operational parameters, especially leaching time and solid-liquid ratio (S/L). Therefore, this study was conducted to determine the effect of leaching time and solid-liquid ratio on the Atmospheric Acid Leaching process, as well as to determine the optimum conditions capable of producing nickel extraction percentage ≥ 80% from laterite nickel ore from Konawe. This study began with the characterization of raw materials using X-Ray Fluorescence (XRF) to determine the initial composition of laterite nickel ore. The AAL process was carried out using a 5 M sulfuric acid solution at a temperature of 90°C, a stirring speed of 400 rpm, and a particle size of -100#. The research variables used included leaching time (2, 4, and 6 hours) and solid-liquid ratio (5%, 10%, and 15%). The leaching filtrate was analyzed using Atomic Absorption Spectroscopy (AAS) to determine the nickel concentration, while the residue was analyzed using XRF. The results showed that leaching time and solid-liquid ratio affected the nickel extraction percentage. The nickel extraction percentage increased with increasing leaching time until it reached an optimum condition at 4 hours, then tended to decrease at 6 hours. In addition, a lower solid-liquid ratio provided a higher extraction percentage than a larger ratio. The highest nickel extraction percentage was obtained at a combination of 4 hours leaching time and 5% solid-liquid ratio, with an extraction value of more than 80%, namely 92.30%.
