Agglomeration and magnetic deinking for office paper

The combination of toner agglomeration followed by magnetic separation prov ides a new deinking process strategy that should have significant impact on the office paper recycling industry. Agglomeration and magnetic deinking c onsist of agglomeration of magnetic and nonmagnetic toner particles to gene rate magnetic agglomerates that magnetic separation can remove. Single-stag e, wet, high-intensity magnetic separation can achieve dirt removal of 91% and fiber recovery of 93% from office paper furnishes.
