Operation

The Metso Outotec OKTOP® Agitators enable reliable and efficient operation in demanding mining, minerals processing and metallurgy applications. Agitators are used in various mixing, solids suspension and gas dispersion duties and are used in both in atmospheric reactors and autoclaves. References range from Conditioners and filter feed tanks to CIL, CIP, BIOX, strong acid leach and precipitation reactors. Currently Metso Outotec agitators have over 600 references around the globe in very diverse applications.

The agitator design and selection is based on our long history of operation on plants and wide range of research in the Metso Outotec research center in Pori, Finland. In Pori we can perform process kinetics, solids suspension, gas dispersion and materials testing for the agitators. We have readily available very experienced CFD experts and CFD is used extensively in product development.

The new SandSense measurement probe has enabled us to measure solids suspension performance of agitators in industry scale equipment with full visibility on the level of solids suspension. Largest diameter of agitator that has been tested with SandSense had diameter of 5600 mm.

For all OKTOP® agitators mechanical design and manufacturing is made by Metso Outotec to ensure high quality of the equipment. Metso Outotec has vast knowledge of material durability in various hostile environments, taking in consideration corrosion and abrasion. Productized quality assurance procedures are utilized and Metso Outotec has history also in using demanding materials often utilized in hydrometallurgy, such as duplex steels, titanium and others.
