    So you can see that substracting LOI without relating to same basis makes you underestimate the calcination degree, but as you stated, the difference will come to zero if calcination is complete. You are also right that the dust cycle influences apparent calcination, but anyway, what is important is the material entering the kiln and cycled dust is part of this.
