Xstrata Nickel’s Koniambo project in New Caledonia is commissioning as it prepares for first ore by the end of 2012. The project design relies heavily on the use of Profibus DP, a digital communications bus, to link field instrumentation and electrical motor controls to the ABB Distributed Control System that is used for control and monitoring of the facilities. Ian Pearce, Chief Executive of Xstrata Nickel, said in November: “We are very excited about the progress being made at Koniambo, including the successful delivery of Line 1.
It is a testament to our dedicated project and operation teams at Koniambo Nickel that we can now focus on moving to first production. “With the completion of Line 1, the majority of our construction resources will now be devoted to the second production line, which is forecast to be complete in the second quarter of 2013. Koniambo Nickel will ramp up to a steady state annual production run rate of 60,000 t of nickel in ferronickel within two years, by the end of 2014.
“Koniambo Nickel’s mine is already operating with the geological integrity of our resource forecasts intact. The ore-preparation plant and overland conveyer are in operation and the team is working to ensure we have 30,000 t of on-spec ore ready for the metallurgical plant by the end of the year.”
Gary O’Connell, Project Technical Director, along with Thierry Bonnet de Larbogne, KNS Process Control Manager, requested XPS Process Control group to assist in troubleshooting of the Profibus installations when problems were experienced during pre-operations testing. The Process Control group has two certified Profibus professionals (Alan Hyde & Phil Nelson) within the group.
