Mechanistic study reveals magnesium extraction pathways from serpentinite rocks using ammonium sulfate, indicating potential improvements in carbon dioxide mineral sequestration efficiency.
There is a growing research interest in CO 2 mineral sequestration methods that follow an intermediate Mg extraction step (from Mg-silicates, especially serpentinite rock) by fluxing with ammonium sulfate (AS) or ammonium bisulfate (ABS).
