摘要

Process of the specified kind characterized in that the spray-separated suspension is separated by a classifier into a fraction containing mainly the fine particles and a fraction containing mainly the coarse particles after which the fraction containing the fine particles is supplied to the thickener or separators and the fraction containing the coarse particles is passed to a separator or magnetic separators to separate the coarse impurities from the suspension with the particles being fed to the classifier and those fed to the primary separator demagnetized before entering the classifier and the separator .
