Leaching Kinetics of Ironmaking Blast Furnace Slag as a Source of Calcium for CO₂ Sequestration by Makhitha Masipa, Itumeleng Kohitlhetse, Hilary Rutto, Kentse Motsetse, Malibongwe S. Manono

“…However, with the smallest particle size fraction, more calcium can be extracted before the surface is obstructed, thus ensuring maximum extraction efficiency. Based on the activation energy value of 70.51 kJ/mol, it is less likely that the leaching of blast furnace slag in ammonium nitrate is a product-layer-diffusion-controlled process, as the activation energy for this type of process is usually below 20 kJ/mol. …”
