The present invention relates to an apparatus for the separation of magnetic constituents from a dispersion comprising these magnetic constituents and nonmagnetic constituents, comprising at least one loop-like canal () through which a dispersion flows having at least two inlets () and at least two outlets (), further comprising at least one magnet () that is moveable alongside the canal (), wherein the canal () is arranged relative to gravity in a way that nonmagnetic constituents are assisted to go into at least the one first outlet () (stream I) by sedimentation and by the current of the dispersion and magnetic constituents are forced into at least one second outlet () (stream II) by magnetic force against a current of flushing water. Furthermore, the present invention relates to a process for the separation of magnetic constituents from a dispersion comprising these magnetic constituents and nonmagnetic constituents.

Apparatus for continuous separation of magnetic constituents and cleaning of magnetic fraction

An apparatus for separating magnetic particles from a dispersion that includes magnetic particles and non-magnetic particles, the apparatus comprising; at least one arcuate canal forming 90 to 350&#xb0; of a circular arc through which the dispersion flows, at least one magnet that is movable adjacent to the canal and which forces the magnetic particles into at least one first outlet, and at least one second outlet through which the non-magnetic particles exit the canal, the apparatus further comprising treating the dispersion, or a part of the dispersion, with a hydrophilic liquid, and treating the dispersion, or a part of the dispersion, with a hydrophobic liquid.

Apparatus for resource-friendly separation of magnetic particles from non-magnetic particles

The present invention relates to a stable mixture comprising surface-modified particles which are obtained by reacting metal oxide or semimetal oxide particles with at least one compound selected from among silicon-comprising compounds bearing at least one metaloxy radical and optionally further alkoxy and/or hydroxy radical(s) and at least one solvent, at least one surface-active substance or a mixture thereof, a process for producing the mixture, the use of these particles in systems in which they are brought into contact with at least one solvent, where the mass ratio of solvent to modified particle is greater than 500, and also the use of these particles in agglomeration-deagglomeration cycles.

Hydrophobic, functionalized particles
