:: Outotec Expands Heavy Mineral Sands Processing Plants in Sierra Leone

Outotec has signed a contract with Sierra Rutile Ltd., a subsidiary of Titanium Resources Group Ltd., for the design and expansion of Sierra Rutile's land-based processing plants in Sierra Leone, Western Africa.

Outotec is working closely with Sierra Rutile Ltd. and is responsible for implementation of the entire expansion project.

The new addition will utilize concentrate from two existing dredges and concentrators. It will first be upgraded using Outotec Spirals and a FLOATEX® Density Separator, and then dried. The dried ore will be sent to the new mineral separation plant for production of final products using advanced HE Rare-Earth Roll Magnetic Separators and eForce® High-tension Electrostatic Separators.

Outotec's laboratories in Jacksonville, USA and Perth, Australia were involved in the extensive testing program and flowsheet design.

The expanded plant, with a design capacity of approximately 300,000 tpa rutile and 70,000 tpa ilmenite, is scheduled for completion in early 2008.
