Abstract
The present invention provides an aqueous solution evaporative treatment method that makes it possible to efficiently perform evaporative treatment of a silica-containing aqueous solution. The aqueous solution evaporative treatment method comprises a seed crystal mixing step of adding to and mixing with a silica-containing aqueous solution a silicate as seed crystals and an evaporative concentration step of evaporatively concentrating the aqueous solution together with the seed crystals. The silicate is preferably magnesium silicate and/or calcium silicate.
