the ore particle magnetic particle agglomerates a can be carried out for example chemically in particular by changing the ph value and or by adding chemical separating agents t also conceivable is the use of ultrasonic waves introduced with an ultrasonic device associated with the second separating device altogether what takes place herein is a mixing process which by applying shear forces and chemical substances in the form of the separating agents t based on surfactants brings about dehyrophobization of the magnetic particles m and the ore particles e thus separating the ore particle magnetic particle agglomerates a into the constituents thereof it is possible that in the second separating device a particular content of gangue g is present which was not able to be properly separated in the previous box 4 process in the box identified as 6 the u201c unload u201d process is largely completed i e a mixture of ore particles e and magnetic particles m which are present together but separately has been created the magnetic particles m present in isolation are magnetically separated via a third separating device comprising a magnetic device in particular a moving field magnetic separator from the non magnetic ore particles e and are transferred to a first mass flow ms 1 containing magnetic particles m evidently the first mass flow ms 1 can be fed back so that the magnetic particles m contained therein can be reused at the start of the process arrow 10 accordingly the whole process can be optimized from the economic and ecological standpoints the ore particles e are transferred to a second mass flow ms 2 which.
