FIELD: chemistry.
SUBSTANCE: natural calcium carbonate with an activated surface or an aqueous suspension containing natural calcium carbonate with an activated surface with pH higher than 6.0, measured at 20°C, is added to the medium. The natural calcium carbonate with an activated surface is a product of reaction of natural calcium carbonate with carbon dioxide and one or more acids.
EFFECT: improved removal of resin from aqueous medium.
