The CaCO3 content of limestone is more than 80%. After being modified by NaOH, the pH of the coal gangue is raised to neutral. Obviously, the pH of the leaching solution is also neutral.
The CaCO3 content of limestone is more than 80%, and after NaOH correction, the pH of coltan is raised to neutral, it is obvious that the liquid pH is also neutral. ...
