L'invention concerne un dispositif (1, 1', 1") de séparation de particules magnétiques et/ou magnétisables (11) d'une suspension (10) contenant par ailleurs des particules non magnétiques et/ou non magnétisables (12). Le dispositif (1, 1', 1") comprend une conduite (2) destinée à faire passer la suspension (10) et comprenant au moins une dérivation (2a, 2a'). Au moins un dispositif (3, 3') destiné à produire un champ magnétique dans la zone de la ou des dérivations (2a, 2a') est agencé à l'extérieur de la conduite (2). La conduite (2) comporte dans la zone de la dérivation (2a, 2a'), sur sa paroi intérieure (20) tournée vers la suspension (10), un revêtement anti-adhérence (4) qui empêche des particules magnétiques et/ou magnétisables (11), à séparer de la suspension (10), d'adhérer à la paroi intérieure (20).
