Abstract

Fragments of recycled paper, of very diverse composition and origin are subjected to chemical and physical treatment to obtain a material of uniform appearance, compsn. and props. for making new paper. Removal of impurities separating from the fibres is carried out by addn. of a surfactant with an organic sequestrating agent, in order to form a micro-foam which acts as a collector and separates the contaminants by entrainment.
