G's) and operates by using a smooth-walled, rotating bowl to stratify the material into heavier and lighter fractions then uses pneumatic valves to control the amount of heavy material that reports to the concentrate collection stream. It does not use any fluidization water and relies entirely on centrifugal force for separation. The Falcon C concentrator is used in various process plants around the world, such as the Tanco mine in Canada, the Sekisovskoye mine in Kazakhstan and the Renison tin mine in Tasmania. Falcon Ultra-Fine The Falcon Ultra-Fine (UF) centrifugal concentrator is primarily used for the separation of heavy minerals which occur in ore concentrations above 0.1% by weight, such as cassiterite, tantalum and scheelite when the majority of the particles are smaller than 75 µm. The machine generates forces up to 600 times the force of gravity (600 G's) and uses a smooth-walled bowl for particle stratification with a pneumatically controlled rubber lip for heavy material collection. The machine is stopped periodically to rinse and collect the valuable concentrate from the bowl. Studies have found that the deposition of heavy material within the bowl can be predicted by a hindered settling model. The Falcon UF concentrator is used in a number of process plants around the world such as the Tanco mine in Canada and the Bluestone tin mine in Tasmania. Sepro Tyre Drive Scrubbers Scrubbers are material washers used to break down and disperse clays in order to prepare mineral ores or construction aggregates for further processing. Sepro Tyre Drive Scrubbers are manufactured up to 3.6m in diameter and are capable of processing up to 1500 tonnes per hour of material. Shell supported Scrubbers such as the Sepro PTD Scrubber minimize stress on the shell by spreading the power drive over the full length of the washing drum. These scrubbers operate in many applications on feeds with high clay content, and are commonly used for difficult ore and stone washing duties. A few specified applications of Sepro Scrubbers include removal of gold “robbing” carboniferous material and other contaminants from gold ores, the processing of bauxite ores for aluminum production, the washing of laterites (gold, nickel, cobalt) to liberate fine metals for gravity recovery, and the washing of crushed aggregate, gravel and sand to remove clay contamination. Sepro Tyre Drive Agglomeration Drums Sepro Agglomeration Drums are specifically designed to prepare feeds with high fines content on Gold and Base
