1. A separating method for separating magnetic particles and non-magnetic particles present in a suspension, the separating method comprising:
(a) feeding-in the suspension via an inlet and thus loading a stirring vessel of a stirring stage with the suspension including the magnetic particles and the non-magnetic particles;
(b) continuously stirring the suspension in the stirring vessel by a stirrer;
(c) conveying, by a conveying device, the suspension through a pipe system, thereby:
(c1) feeding the suspension to a screening stage and screening the suspension by a wet screen, thereby screening out particles which are larger than a mesh width of a screen base of the wet screen to provide screened-out particles,
(c2) further feeding the suspension to a particle filter stage and filtering the suspension in at least one particle filter of two particle filters, the two particle filters each comprising a bag filter and each having a filter membrane having a pore diameter in a range from 0.5 μm to 5 μm or in a range from 50 μm to 500 μm,
(c3) unloading the screen base of the wet screen by moving the screen base from a screening position into an unloading position and discharging the screened-out particles into the stirring stage,
(c4) further feeding the suspension to a magnetic filter stage and, by a magnetic filter, filtering the magnetic particles and thereby separating the magnetic particles from the non-magnetic particles, and
(c5) feeding the non-magnetic particles to the stirring stage; and
(d) after at least one cycle of (b) to (c5), discharging the filtered and screened suspension from the stirring vessel via an outlet.
