This study investigates scandium recovery from Indonesian limonitic laterite ore using atmospheric pressure acid leaching (APAL) with sulfuric acid (H2SO4) and acetic acid (CH3COOH) as lixiviants. Leaching temperature (30–90 °C) and pH (ranging from − 1.2 to 1.24 for H2SO4; 2.13 to 2.87 for CH3COOH) were varied to evaluate their influence on extraction efficiency. Response Surface Methodology (RSM) was applied to model process performance and identify optimal conditions. Results showed that lower pH (i.e., more acidic conditions) and higher temperatures significantly enhanced scandium recovery. Sulfuric acid achieved a maximum recovery of 92.94% at 90 °C and pH − 1.2, while acetic acid reached 56.47% at 90 °C and pH 2.13. XRF analysis confirmed scandium content of 79 ppm in the ore, indicating its potential as a feedstock for critical metal extraction. Compared to high-pressure acid leaching, the APAL approach offers a lower-energy, safer, and cost-effective alternative, especially in decentralized or infrastructure-limited regions. The use of acetic acid also presents a more environmentally friendly option.
