Abstract: The invention is directed to a process for separating particles using a wet density-based separation device, wherein at least part of said particles are coated prior to being fed to said density-based separation device. In accordance with the invention separation medium that is employed in density-based separation processes can be saved.
Abstract: A system and method for magnetic density separation of products. The system including a magnet configured to amplify a density gradient in a magnetic liquid for separating the products in the magnetic liquid according to their different density. A plate shape is disposed along a product path where respective products travel through the magnetic liquid. A driving mechanism is configured to drive the plate shape with a reciprocating motion for lowering a static friction of the respective products coming into contact with the plate shape. Accordingly, process continuity can be improved while maintaining a high separation efficiency, in particular by alleviating material build-up and clogging of products at the splitter and other surfaces with minimal disturbance to the process flow.
