  • the specification of the variation can be generated, for example, by influencing a current flow through corresponding means, as a rule coils. This can be a targeted, easy and repeatable a variation of the magnetic forces.
  • the variation of the geometric arrangement in the deposition step is also conceivable, in order to change the magnetic forces which cause the deposition, and thereby to achieve a corresponding and desired variation of the magnetic forces.

By doing so, the use of resources is reduced; because by using the method can be achieved that less of the first substance is contained in the Restprimstoffstoffstrom at the same time the least possible effort for the preparation (connection) of the first substance to the carrier particles.
  • a content of the first substance for the secondary material flow or for the primary material flow is determined, and at least one parameter of the separation process also adjusted on the basis of the content. While the change in the content may tend to indicate the quality of the mixing step, depending on the given variation, the determination of the content of the first substance, either in absolute or relative form, allows a conclusion on how well the separation of the first substance from the primary stream overall or at a certain mixing result in terms of the connection of the first substance to the carrier particles works. In the method described above, the lowest possible content of the first substance in the residual primary stream is generally desired, while in the secondary material stream, on the other hand, the highest possible content is desired.
  • the mass of the first substance in the secondary material flow plus the mass of the first substance in the residual primary stream is equal to the mass of the first substance in the primary material flow

If, for example, the determined content is low and the amount of the change in the content as a function of the predetermined variation is small, then it is expedient to first optimize the mixing step and not the deposition step.
  • This exemplary combination of content and salary change for a given variation indicates that the mixing step is not working effectively. This is evident from the fact that the change of the content is small depending on the variation. This means that given a given variation, the change in the content is low, that little first substance is attached to the carrier particles. However, a prerequisite for a high content of first material in the secondary material flow is that the first substance is also bound to the carrier particles, since otherwise no deposition of the first substance with magnetic forces can take place. Consequently, first of all the connection of the first substance to the carrier particles has to be improved, before then an optimization of the content takes place by setting parameters of the deposition step.
  • the change in the content as a function of the variation is large (eg above a certain reference value, in particular threshold value), the content of the first substance in the secondary material flow is low, this means that the binding the first material to the carrier particles is good, however, the deposition parameters must be adjusted in the deposition step in order to increase the content.
  • the first phase serves to find economically meaningful operating parameters or parameter values.

For example. these are the mixing energy, in particular shearing energy or shear rate of the mixer, the mixing time, the mixing agents used (ie agents which cause the mixture), the concentration of magnetic carrier particles used, in particular depending on the present concentration of the first substance, the rate of addition of magnetic carrier particles in the primary material flow, the rate of addition and concentration of agents used, which cause a binding of the first substance to the magnetic carrier particles, eg Hydrophobing agent, the liquid content or solid content in the primary material flow, etc.
  • the parameters of the mixing step are adjusted such that the amount of change in the content is increased as a function of the predetermined variation, in particular for a given content.
  • the connection of the first substance is improved to magnetic carrier particles, whereby the separation is more economical with the same predetermined variation, since now an increased proportion of the first substance can be deposited when optimizing the deposition step.

  • a content of the first substance in the secondary material flow or the carrier particles in the residual primary flow is determined and at least one parameter of the separation process is also adjusted on the basis of the determined content.
  • the statements made above regarding the determination and use of the content apply analogously.
  • the content of carrier particles in the residual primary stream allows the control or regulation of the process such that only a certain content of carrier particles in the residual primary stream is included. This has a direct effect on the cost-effectiveness of the process, since carrier particles still contained in the residual primary stream can generally only be removed from the latter at great expense if they have passed the separation device once and are not traceable back into it.
  • magnetic carrier particles in particular for a "load process”, ie the bonding of a nonmagnetic first substance to magnetic carrier particles for removing agglomerates of carrier particles and particles of the first substance from a flowable primary substance stream, are required for a continuous process, these are too replace and must be rebuilt and fed into the process. It is also advantageous to determine the content of the first substance in the secondary material flow and to adjust parameters of the process, in particular of the separation step, based on this content. Because with side by side, but unbound present first substance and carrier particles, the content of the first material in the secondary material flow can be influenced by the deposition conditions.

  • a machine-readable program code 6 is present, which is stored for example by means of data carrier 5 or by means of a network connection to the control and / or regulating device 4 memory-programmed.
  • FIG. 5 shows a diagram in which curves to the content of the ore fraction in the secondary material flow as a function of the magnetic flux density B is shown.
  • the different curves show the ore content at different operating states E1 to E4 of the segregating device 2 ', ie parameterized according to a degree of solution.
  • the ratio of previously bound ore particles S1, which are now dissolved by the carrier particle M, to the total ore content of the material stream is referred to as a degree of dissolution.
  • the degree of dissolution should ideally be 1, i. After passing through the demixing step, no ore particles S1 should be more attached to the carrier particles M.
  • the carrier particle fraction in the residual primary stream R (S1) can be done, for example, via the magnetization of the carrier particles M and a corresponding coil arrangement. In this way it can be determined whether the separation device 3 is set optimally. If this were the case, both non-dissolved ore-carrier particle agglomerates MS1 and the carrier particles M dissolved by the ore would be enriched in the secondary stream S (M). If, on the other hand, significant quantities of carrier particles M in the residual primary fuel stream (RS1) still remain, this is an indication that the operation of the separating device 3 is to be improved. No figure is shown for this measurement.
  • FIG. 6 a flowchart is shown which represents a schematic representation of an exemplary sequence of the method according to the invention.
  • a first method step 100 ' segregation takes place in the demixing device 2' of the separating device 1 '. instead of.
  • the bonds between ore particles S1 and carrier particles M are solved. This is done, for example, by adding appropriate chemicals tailored to the bonding chemistry with which the bond between ore particles S1 and carrier particles M was generated. Also, other mechanisms are possible that cause a solution.
  • the primary material flow P (M / S1) thus contains separately no longer bound ore particles S1 and carrier particles, see FIG. 4 ,
  • carrier particles M and ore particles S1 present in dissolved form are separated by means of magnetic forces in the separation device 3.
  • Carrier particles M are enriched in the secondary material flow S (M).
  • residual primary stream R (S1) ore particles S1 are enriched.
  • a predetermined variation of the parameters influencing the magnetic forces for deposition takes place.
  • the above statements apply analogously.
  • a method step 103 the change in the content of ore particles S1 in the secondary material flow S (M) caused by the variation of the parameter (s) is determined and from this the change in the content of ore particles S1 as a function of the variation is determined in a method step 104.
  • a reference value should be selected in the form of a first threshold value SW1 'greater than zero, but so small in magnitude that this only a possibly existing change of the physical entry by the variation considered. That is to say, as soon as ore carrier particle agglomerates MS1 are present in a specific, not insignificant concentration in the primary material flow P (M / S1), the first threshold value SW1 'is exceeded.
  • a factor greater than or equal to 1 can also be multiplied by the ore content corresponding to the natural limit (by physical input) in order to generate a threshold which is to be undershot.
  • any carrier particles M should no longer be contained in the residual primary stream R (S1). If a change in the parameter influencing the magnetic forces also causes a change in the content of carrier particles M in the residual primary stream R (S1), this indicates that the separator 3 is not operated optimally and carrier particles M are lost. However, in the case of the carrier particles M in the residual primary stream R (S1), the content, ie the relative or absolute content of carrier particles M in the residual primary stream R (S1), is determined. This can be done, for example, by means of a corresponding coil arrangement which uses the magnetization of the carrier particles M as the measurement basis.
  • the threshold value of the ore content in the secondary material stream S (M) does not fall below in method step 105, a setting of the operating parameters of the demixing device 2 'takes place in a method step 106 in order to achieve a better solution of ore particles S1 and carrier particles M.
  • the secondary material flow S (M) and the residual primary flow R (S1) are preferably returned to the demixing device 2 'until the first threshold value SW1' is exceeded.
  • a method step 107 the content of the carrier particles M in the residual primary stream R (S1) is now detected. This is then compared in a method step 108 with a reference value in the form of a second threshold value SW2 '.
  • the second threshold value SW2 ' indicates what loss of carrier particles M in residual primary stream R (S1), which in this example consists essentially of an aqueous suspension with ore particles S1, is still acceptable to the operator.
  • the loss of carrier particles M also has a great influence on the economy of the process since the carrier particles M contained in the residual primary stream R (S1) must be replaced sooner or later. In general, therefore, one will select a second threshold SW2 ', which is 1% or less of the amount of carrier particles M used. However, the choice of the second threshold value SW2 'can be adjusted depending on the first substance S1 and the carrier particle M used.
  • the deposition conditions are adapted in a method step 109 in order to control the discharge of the carrier particles M from the primary substance flow P (M / S1) to improve and reduce the content of the magnetic carrier particles M in the residual primary stream R (S1) to below the second threshold SW2 ', preferably to zero.
  • the entire process is carried out as a controlled by a control and / or regulating device 4 and continuously optimized, for example, the purity of the secondary material stream S (M) and the residual primary stream R (M) is maximized, wherein the coupling of the streams is taken into account so that the separation device 1 'is operated optimally economically.
