Agglomeration and magnetic deinking for office paper

The combination of toner agglomeration followed by magnetic separation provides a new deinking process strategy that should have significant impact on the office paper recycling industry. Agglomeration and magnetic deinking consist of agglomeration of magnetic and nonmagnetic toner particles to generate magnetic agglomerates that magnetic separation can remove. Single-stage, wet, high-intensity magnetic separation can achieve dirt removal of 91% and fiber recovery of 93% from office paper furnishes. Application: Toner agglomeration with magnetic separation is an effective deinking process strategy for recycling of office paper.
