METHOD FOR CLEAN FIBER RECOVERY FROM CONTAMINATED ARTICLES INVOLVING THE ADDITION OF MAGNETIC PARTICLES

摘要

A method (10, 110) for cleaning fibers from a contaminated article is disclosed. The method (10, 110) can include providing a contaminated article comprising contaminates and at least one of fibers and filaments. The method (10, 110) can further include adding a plurality of magnetic particles (18, 118) to a first solution and pulping (20, 120) the contaminated article to separate the at least one of fibers and filaments from the contaminated article to provide dissociated pulped fibers. The method (10, 110) can further include applying a magnetic field (22, 122) to the suspension including the dissociated pulped fibers and removing (26, 126) at least some of the plurality of magnetic particles and at least some of the contaminates from the suspension. The dissociated pulped fibers can be dried (34, 134) to provide clean fibers.
