xerographic paper rotogravure heat set including coated and uncoated stock and high gloss multi colored paper such as magazines moreover the process enables the de inking of higher pulp densities than typical prior art methods as noted above in conventional de inking processes the waste paper is first pulped and the ink particles are removed by using a flotation technique in this step the pulp at a solids loading of 1 0 1 25 wt is treated with various reagents to separate the ink particles from the fiber the ph of the pulp is adjusted using naoh reagents are then added to emulsify or discharge the ink particles from the fiber interface and a collector is added to float the liberated ink particles air is sparged into the pulp stream in order to aid the flotation process typical de inking process chemicals currently used are shown in table 1 in the method of the invention in the de inking step the pulp is treated with a novel reagent scheme which is far less costly than conventional de inking and flotation reagents briefly to a pulp stream are added a soluble peroxide and a soluble alkaline agent capable of undergoing a reaction with the peroxide to liberate a bubble of gas which functions to float the ink particles in the pulp stream to the surface fig1 depicts a flow sheet of a typical de inking process of the invention the pulp stream is reagentized with 0 5 1 0 wt hydrogen peroxide and 0 1 0 2 wt ammonia as ammonium hydroxide the ph in this stage is about 9 5 10 0.
