Outotec has received a repeat order from London Mining for delivery of High Gradient Magnetic Separators (HGMS) to the Marampa iron ore project in Sierra Leone. London Mining, a UK-based company that is developing mines for the steel industry, purchased the first magnetic separators for the project in 2010. The combined value of the orders and services is over US$13.5 million.
Outotec partnered with London Mining to develop the flowsheet for processing tailings (haematite) from former operations at Marampa. The installation of the first Outotec magnetic separators is nearly complete with start-up expected in 2011. The rest of the equipment will be delivered in early 2012. This stage of development will take London Mining’s Marampa concentrate output to 3.6Mt/y. A recent pre-feasibility study has outlined a further expansion to 16Mt/y of premium iron ore concentrate.
Pertti Korhonen, president and CEO of Outotec, said: "This is the largest delivery of the Outotec magnetic separators of this scale to a single site. Besides this delivery, we are currently working with London Mining's technical team to provide process development services that will support the Marampa project in its later stages.”
