Abstract
The present invention provides an aqueous solution evaporative treatment method that makes it possible to efficiently perform evaporative treatment of an aqueous solution containing calcium, magnesium, and silica. The aqueous solution evaporative treatment method comprises a seed crystal mixing step of adding to and mixing with an aqueous solution containing calcium, magnesium, and silica at least any one of magnesium salt and silicate together with calcium salt as seed crystals, and an evaporative concentration step of evaporatively concentrating the aqueous solution together with the seed crystals.
