The invention concerns an online method and system for monitoring properties of an aqueous stream of an industrial process. The method comprises providing an initial aqueous stream originating from said process, the aqueous stream containing solid matter exhibiting a first settling behavior; adding modifying agent to the initial aqueous stream at an addition rate sufficient to provide a modified aqueous stream containing solid matter exhibiting a second settling behavior different from the first settling behavior; conducting a sample of the initial aqueous stream or modified aqueous stream, any combination stream comprising the modified aqueous stream or any substream of the modified aqueous stream batchwise from a sampling point to a settling vessel having a volume; and measuring the settling behavior of the solid matter in the sample locally in the settling vessel as a function of time. The invention can be used for efficient monitoring and, optionally, controlling the degree of agglomeration of pulp and paper or board manufacturing processes.

A means to exploit the Dean Vortices for dynamic filtering on a macro scale intended for application in utility and industrial processes is disclosed. This method relies on an apparatus of computed construction to optimize the centripetal force and minimize the effect of gravity on the separation and effectiveness of the Dean Vortices. The method is also supported by an apparatus of construction which results in an optimized elliptical flow channel that enhances the formation and persistence of the Dean Vortices.

Method and apparatus are provided to select target metal particles from aggregate ore. A feed stream of aggregate is directed along a path and a higher density portion is segregated therefrom. Detectors are arranged in-line and along the flow of the higher density portion. High resolution detection of a target particles within the feed stream triggers ejection of a select portion of the feed stream and target particle as a concentrate and the balance continues to a further phase of detection/ejection. The concentrate is processed in further stages or collected as product. Multiple parallel detector/ejectors across the path can isolate target particles and minimize the ejected gangue portion associated therewith. Dry or hydrodynamic transport of the feed stream is available determined by aggregate characteristics. A compact footprint of the apparatus is achieved with arcuate paths and multi-level conveyance whilst low energy requirements enables use in artisan installations.
