Abstract

In a delignification of pulp with hydrogen peroxide catalysed with molybdate molybdate can be recovered by bringing the aqueous solution containing molybdate into contact with a carrier material that comprises a layered silicate ion exchanged with a quaternary ammonium salt at a pH value ranging between 2 and 7 and subsequent flotation without the need to add a tenside for the flotation.
