TURBULENT TECHNOLOGIES
TENOVA. INNOVATIVE SOLUTIONS FOR METALS AND MINING
Unlock Potential, Create Value
Tenova Advanced Technologies (TAT) offers differentiated, project-specific process technologies based on decades of esearch, equipment design and project execution. Advanced solutions include solvent extraction (SX) and electrowinning (EW) for the mining and chemical industries, membrane circuits, in-house state-of-the-art R&D facilities, expertise in minerals beneficiation as well as phosphate processing from ore to purified phosphoric acid and salts.
The TT Mixing System with its advanced design, enhances separation in the settler, and provides many advantages compared to the conventional mixing systems used in solvent extraction circuits. It enables significant reduction of entrainment levels without changing the process flow and can easily be retrofitted to existing mixer settlers or installedin new plants.
TAKRAF, a Tenova Group company, is an integrated solutions provider to the global mining, bulk material handling, minerals processing and beneficiation industries, offering innovative technological solutions as well as process and commodity knowledge along the industry value chains. With the integration of the well-known DELKOR and Tenova Advanced Technologies (formerly Bateman Advanced Technologies) brand of products into TAKRAF as specialized product lines, our portfolio for the minerals processing and beneficiation sectors has been considerably enhanced.
The Turbulent Technologies Mixing System developed by Turbulent Technologies is based on a patented “Method for Coalescence Induced Liquid/Liquid Separations and Apparatus Thereof”
SELECTED PROJECTS
The Turbulent Technologies Mixing system is used to improve coalescence in mixer settler operations by applying special impeller and baffle designs inside a mixing tank.Several early adopters of this innovative technology are already reaping the benefits of installing the TT Mixing System in their operations.

THE TENOVA TURBULENT TECHNOLOGIES MIXING SYSTEM
Tenova Turbulent Technologies Mixing System is a new mixing technology which enables significant reduction of entrainment levels without changing the process flow. It can be easily retrofitted to most existing mixer settlers or installedin new SX plants.
Unique capabilities:
Advantages:
� Creates uniform dispersion in the mixing tank (avoiding formation of small droplets) � Predictable and controlled drop size distribution as a function of the mixing regime, allowing process optimization � Increase throughput while maintaining optimum mixing conditions � Increased throughput with no increase in entrainments
The Tenova solvent extraction systems are backed up by a comprehensive range of services, starting with bench scale exploratory tests through to pilot scale test work, culminating in the design, construction and commissioning of full-scale solvent extraction plants.An essential component of TAT‘s service is the expertise of its solvent extraction engineers and their access to in-house pilot-scale equipment.
� Reduces entrainment of expensive extractants � Reduces organic contamination in the product stream � Reduces aqueous contamination in the loaded organic stream � Reduces ecological impact of organics in the raffinate stream � Enables increased settling flux � Reduces operation and maintenance costs � Eliminates the need for after-settlers

HOW THE TURBULENT TECHNOLOGIES MIXING SYSTEM WORKS
Mixing a two-phase system involves a dynamic process of droplet breakage and coalesence. The TT Mixing System agitator design increases the frequency of the two processes and changes the dynamic balance between them, withoutcreating small droplets that make separation difficult. The resulting droplet size distribution has a larger average drop size, and a narrower distribution, which reduces settling time and entrainment of water in organic and organic in water phases.The TT Mixing System also provides an even distribution of the mixing energy throughout the tank, for optimal mass transfer.
