When the pH reaches 1.8, the grade of CaCO 3 abruptly increases to 30.81%. Therefore, the CaCO 3 peak can be detected at this pH point, which is consistent with the XRD pattern. At the same time, it can be seen that under low pH, the grade of CaCO 3 was about 3%, so the first mineralization should be carried out under lower pH.
