Source sentences:
text: If the fluorine concentration of the solution exceeds 20% by weight, the concentration of the formed calcium fluoride slurry becomes too high that it can hardly be handled, and the SiO 2 concentration of the solution becomes too high and gelling of SiO 2 is accelerated so that a mixing amount of SiO 2 in CaF 2 to be recovered is unfavorably increased.
text: If the residence time is too short, an amount of unreacted calcium carbonate is unfavourably increased.
