OUTOKUMPU TECHNOLOGY TO DELIVER NEW ZINC LEACHING TECHNOLOGY TO CHINA

Outokumpu Technology has agreed with the leading Chinese zinc producer, Hunan
Zhuye Torch Metals Co. Ltd., a fully owned subsidiary of Zhuzhou Smelter Group
Co. Ltd, for the design and delivery of a zinc plant expansion with new
environmentally sound leaching technology. The plant is located close to the
city of Zhuzhou, Hunan province in China. The contract value is nearly EUR 30
million.

Outokumpu Technology’s delivery includes the engineering of a zinc plant with
new Atmospheric Direct Leaching Process, iron precipitation and solution
purification processes, main equipment supplies as well as supervision of
installation and commissioning. The expansion will increase the plant capacity
by 100 000 tonnes of zinc per year and the plant is estimated to be operational
by July 2008.

Outokumpu Technology has developed a new process for zinc concentrates, called
Atmospheric Direct Leaching Process, which eliminates the conventional roasting
phase in zinc processing. The process is already in use in Boliden’s Kokkola
zinc plant in Finland and Odda zinc plant in Norway. Hunan Zhuye Torch Metals
selected this process for its expansion because it is an environmentally sound
way to produce zinc, it includes recycling of process residues, and it
represents the latest technology. A wider selection of zinc concentrates can be
used as raw materials in the process, which improves the use of resources.

In order to expand the use of Atmospheric Direct Leaching Process in China,
Outokumpu Technology has also signed a Collaboration Agreement with Zhuzhou
Smelter Group Co. Ltd.
