A magnetic drum separator (), with a drum () rotatable about a rotational axis (), a magnet arrangement () of a plurality of magnets () arranged in the interior () of the drum (), a separation zone () in the exterior space () of the drum (); a feed material () flows through the separation zone () and is there separable with the aid of a magnetic field () generated by the magnet arrangement (), into a waste stream () and a recyclable material stream (). A relative position (R) of at least one of the magnets () relative to the rotational axis () can be varied. A nominal magnitude (S) for a process value () on the drum separator () that is influenced by the separation behavior () is specified. At least one measurement device () detects an actual magnitude (I) of the process value (), and a controller (), which changes the relative position (R) of the at least one of the magnets (), whereby the actual magnitude (I) is controlled to approach the nominal magnitude (S).

Magnetic drum separator and method for operation thereof

A method obtains non-magnetic ores from a suspension containing ore particle-magnetic particle agglomerates. The method involves dividing ore particle-magnetic particle agglomerates precipitated from the suspension into a mixture of separately present ore particles and magnet particles, separating the magnetic particles from the mixture, forming a first mass flow containing magnetic particles and a second mass flow containing ore particles. At least one information describing a measure of the content of ore particles in the first mass flow and being associated with the first mass flow and/or at least one information describing a measure of the portion of magnetic particles in the second mass flow and being associated with the second mass flow are determined in order to determine the efficiency of at least one of the separation processes described above.

Method for obtaining non-magnetic ores from a suspension containing ore particle-magnetic particle agglomerates

A method obtains non-magnetic ores from a suspension-like mass flow containing non-magnetic ore particles. The method involves mixing the mass flow with magnetic particles in a mixing device and forming ore particle-magnetic particle agglomerates, feeding the mass flow as a separator feed flow to a magnetic separator for separating the ore particle-magnetic particle agglomerates from the mass flow, forming a separator concentrate flow containing ore particle-magnetic particle agglomerates and a separator residual flow containing the remaining constituents of the mass flow, and separating the ore particles from the ore particle-magnetic particle agglomerates contained in the separator concentrate flow. At least one information indicating a measurement of the content of ore particles or magnetic particles in the separator feed flow and/or the separator concentrate flow and/or the separator residual flow is determined for determining an efficiency of at least one of the mixing apparatus and/or the magnetic separator.
