Dataset associated with the paper "Electrodialysis for concentrating cobalt, chromium, manganese, and magnesium from a synthetic solution based on a nickel laterite processing route"

This dataset contains experimental results on the recovery of Co²⁺, Mg²⁺, Mn²⁺, and Cr³⁺ ions from an acid multicomponent solution generated during nickel laterite processing using electrodialysis. The data include ion concentrations, percent extraction, current efficiency, energy consumption, solution pH over time, and speciation diagrams. This dataset is suitable for studies on metal recovery, ion transport in multicomponent systems, and electrodialysis process optimization. The data used to generate the figures are provided in the corresponding Excel worksheets. Each dataset is specified below.
