摘要: Abstract Single-stage mineral carbonation is undertaken at relatively high pressures (up to 18 MPa) and temperatures 185 °C), where in contrast, two-stage operates low ( Multi-stage grinding was investigated an effort obtain a higher level of Mg extraction. However, it observed that the average particle size ground product increased during second stage multi-stage grinding. It suggested this increase limited extent extraction phase The determined be due agglomeration fines subsequently polyacrylic acid, commercially available media aid applied order reduce agglomeration.
