Abstract: A process and a system for producing a stock solution for production of a ferrofluid is provided. The process includes contacting an acidic solution in a reaction container filled with an excess of a bulk material containing Fe(III) and optionally Fe(II). The acid reacts with the bulk material to form the stock solution (Ls) having dissolved ferric (Fe(III)) and optionally ferrous (Fe(II)) ions which is then separated from the bulk material.

Abstract: A separation apparatus, comprising an identifier arranged to identify the particles in a group of particles that have a specific property, an affinity modifier arranged to modify an affinity of the identified particles relative to that affinity of non-identified particles in an group, and a separator arranged to separate the particles in the group based on their difference in the affinity.

Abstract: A planar magnet for magnetic density separation, comprising an array of pole pieces succeeding in longitudinal direction of a mounting plane, each pole piece having a body extending transversely along the mounting plane with a substantially constant cross section that includes a top segment that is curved to distribute the magnetic field associated with the top surface of the pole piece such that its strength transverse to the mounting plane is substantially uniformly distributed in planes parallel to the mounting plane, the curved top segments having a width (w) in longitudinal direction of the mounting plane and a maximum height (h) transverse to the mounting plane, wherein the top segments of successive pole pieces are unequal in height and/or width.

Abstract: A magnetic density separator includes a process channel, a magnetization device, a laminator, and a feed including an entraining device. The process channel may permit magnetic process liquid and particles to be separated to flow through in a flow direction. The magnetization device may be arranged to extend in flow direction along at least one of the walls of the channel and to apply a magnetic field to the process liquid in a separation zone of the channel to establish a cut density of the magnetic process liquid to separate the particles in the process liquid based on their density. The laminator may be configured to introduce magnetic process liquid into the channel to flow laminarized in flow direction along the separation zone. The feed may introduce a mixture of process liquid and particles to be separated into the process channel to join the laminarized process liquid.
