Abstract: The present invention is a segmented bowl for a batch centrifugal concentrator constructed from a plurality of segments that are each placed adjacently to one another, so that each segment is in intimate contact with its neighbouring segments, so that when a sufficient number of segments are put into place, they form the bowl of the batch centrifugal concentrator.

Abstract: A modular ore processing system for concentrating ores includes a plurality of separate modules constructed so as to be serially arranged to form a feed processing system for concentrating a desired material in the ore, wherein the modules are individually transportable to a processing site to be operationally coupled to form the modular ore processing system.

Abstract: A separation apparatus comprising, a series of compartments for holding particulate separation material, arranged so as to allow fluid to flow through the compartments in a primary direction from a first compartment in the series to a last compartment in the series, feed means for directing a flow of the fluid into the first of the series of compartments in the primary direction, barrier means for preventing flow of particulate separation material between compartments in the primary direction, and a pumping assembly arranged to pump a mixture of the particulate separation material and the fluid from the first compartment into a recovery stage.

Abstract: A magnetic separator for a mineral feed comprising, a rotatable drum having an attraction surface, an inlet for receiving a stream of the mineral feed and directing it past the rotating drum, means for generating a magnetic field to attract magnetic components in the feed to the attraction surface, a first zone for take off of non-magnetic components of the mineral feed, and a second zone for take off of the magnetic components, wherein the magnetic field generating means are adapted to subject the magnetic components to at least one reversal of polarity of the magnetic field as the drum rotates.
