Recovery of high-purity magnesium hydroxide from salt-lake bittern by lime precipitation: crystallization and washing optimization

This dataset contains the full L25(56) orthogonal array design matrix supporting the findings of the manuscript "Recovery of high-purity magnesium hydroxide from salt-lake bittern by lime precipitation: crystallization and washing optimization." The data were obtained from crystallization experiments performed on salt-lake bittern using lime precipitation. Six factors were investigated: Mg concentration (0.3 - 2.0 mol/L), Ca/Mg molar ratio (0.3 - 1.1), reaction time (60 - 360 min), temperature (293.15 - 353.15 K), aging time (30 - 150 min), and stirring speed (60 - 300 rpm).

For each experimental run, the particle size parameters D10, D50, and D90 were measured. The dataset is provided as a single Excel (.xlsx) file .
