Understanding the variability of leaching kinetics is extremely challenging due to the nature of leaching processes. Common experimental setups, such as column leaching experiments, only allow for quantification of apparent leach kinetics at the macroscale (e.g. at the particle or column level), failing to capture grain-scale variability. In this paper, we study variability in leaching kinetics at the micro- and macroscale using a combination of 4D imaging and standard chemical measurements.

氯离子对黄铜矿浸出的影响：多尺度、多模式评估


由于浸出过程的性质，了解浸出动力学的变异性极具挑战性。常见的实验设置，例如柱浸出实验，仅允许在宏观尺度（例如颗粒或柱水平）量化表观浸出动力学，无法捕获颗粒尺度的变化。在本文中，我们结合 4D 成像和标准化学测量来研究微观和宏观尺度浸出动力学的变化。
