Overview

Flotation Deinking Paper Recycling DeInking Waste Paper

The pulping consisted of disintegration of the wastepaper structure and dispersion of the fibers The disintegration was accomplished by conditioning 250 grams of wastepaper, under moderate agitation, with hot steam (84 to 90 °C), deionized water and reagent as desired After disintegration the pulp was further dispersed in a high speed blender All pulping experiments were done at a

Introduction to Mineral Processing Chevron Phillips Chemical
