  • Method for concentrating magnetically separated components from ore suspensions and for removing said components from a magnetic separator at a low loss rate
    Patent number: 8646613
    Abstract: The present invention relates to a process for separating magnetic constituents from an aqueous dispersion comprising these magnetic constituents and nonmagnetic constituents by passing the aqueous dispersion through a reactor space in which the aqueous dispersion is separated by means of a magnet installed on the outside of the reactor space into at least one stream I comprising the magnetic constituents and at least one stream II comprising the nonmagnetic constituents, wherein the magnetic constituents in stream I are treated with a flushing stream, a reactor comprising a reactor space, at least one magnet installed on the outside of the reactor space, at least one inlet, at least one outlet for a stream I and at least one outlet for a stream II and at least one facility for treating stream I with a flushing stream, and also the use of this reactor in the process of the invention.
