Abstract
A process for separating foreign matter from calcium carbonate, i.e. lime sludge, formed in the chemical recovery system in connection with the production of cellulose, in which process lime sludge is soaked in a solution containing carbonate or sodium bicarbonate in order to dissolve foreign matter, after which lime sludge is separated out from the solution containing dissolved foreign matter.
