Outotec Oyj: Outotec to deliver tailings treatment plant for Yara's Siilinjärvi mine


Outotec to deliver tailings treatment plant for Yara's Siilinjärvi mine

Outotec has agreed with Yara Suomi Oy on the design and delivery of a paste
plant for tailings treatment.The contract, valued at over EUR 40 million, has
been booked in Outotec's third quarter order intake.

Outotec's EPC delivery includes engineering, equipment supply, construction
and commissioning of the paste plant as well as spare parts and services. The
new plant is expected to become operational in the first half of 2017.

Siilinjärvi mine produces about one million tonnes of apatitite concentrate,
which creates approximately 10 million tonnes of tailings per year. The
tailings, a mixture of sand and water, are currently disposed in the tailings
storage facility as conventional tailings slurry. The new high density
tailings disposal system with dewatering will increase the percentage of
solids in the slurry, making it possible to deposit as paste and extending
the lifetime of the tailings storage facility. Reclaim water is returned to
the process water circulation.

"Yara is our long-term partner with whom we have developed and pilot tested an
optimal thickened tailings solution based on Outotec's paste thickener
technology. Extended lifetime of the existing tailings surface facilities and
efficient water circulation are noteworthy from the environmental point of
view", notes head of Outotec's Minerals Processing business area Kalle
