Separation of polymer fiber from shredded carpet pieces involves mixing a second solid rich phase with a water-containing separating solution and a strong acid and the separation of the extracted suspension

A suspension is taken from a stirring tank containing carpet pieces and a separating salt-containing aqueous solution and centrifuged to produce two solid-rich phases and a fluid phase. The second solid rich phase is mixed with a water-containing separating solution in a second tank. A second suspen...
