The present invention provides for a device and process for extracting heavy particles from lighter particles. The inventive device uses a unique riffle action, causing separation of heavy mineral from waste material, in combination with centrifugal force to retain the separated minerals in the concentrator. The concentrator processes a wide range of particle size feed for the extraction of heavy minerals. The device and process of the invention can extract a great percentage of very fine particles, as well as coarser particles. The machinery of the process can be installed in a roadworthy trailer for delivery and use at the excavation site.
