The overall investment cost for the calciners is around 62 million euros, out of which roughly 50 million euros will be booked in Outotec’s order intake in the third quarter.
Outotec’s scope of delivery includes process technology and design, civil work, detail engineering and construction as well as spare parts for the two alumina calciners, each with a capacity of 3,500 tons of alumina per day.
The project is scheduled to be completed at the end of 2013.
“Outotec calcination technology is clearly the industry benchmark thanks to its very low energy consumption, and I am confident that our partner will also benefit from very low emission levels as well as the sustainable use of raw materials, reliable operation, high material recovery and low lifetime costs,” said Outotec CEO Pertti Korhonen.
“Our strong experience in large projects is demonstrated by the fact that we have designed and delivered the world’s largest sulfuric acid plant complex for Maaden at the same Ras Al Khair site and our track record includes over 50 alumina calciners worldwide.”
