NEWS-CONTINUED (Australia/Oceania Regional News - from p. 16) plant. Run-of-mine ore at an average grade of 0.87 g/mt gold will be crushed in a single 42-65 gyratory crusher. The grinding circuit consists of a 10.2-m-dia, 11-MW SAG mill operating in open circuit, with a pebble crusher reducing oversize mill discharge. A 7.9-m-dia, 15-MW ball mill (Europe Regional News - from p. 22) The company has been targeting shipment of 1.5 million mt of high-quality iron ore concentrate during 2013 and has a goal of reaching its design operating rate of 4 million mt/y by the third quarter of 2014. operating in closed circuit achieves a final grind size of 80% passing 90 µm. Five leach and five adsorption tanks, each of 4,050 m3 capacity, provide a total leach and adsorption residence time of 24 hours. Acid washing and elution of loaded carbon will be performed in separate columns using the split Anglo American Research Laboratories (AARL) process. Carbon-in-leach plant discharge will be thickened using a 34-m-dia, high-rate thickener prior to deposition in the tailings storage facility. The study lists principal project infrastructure consisting of access roads, a 142-person accommodation facility, borefield, tailings storage facility, and electrical power supply. Northland previously announced that it had entered into off-take contracts with three companies for the entire production from the Kaunisvaara project over the next seven to ten years. Northland got into its current financial bind in part because it decided to fast- track construction by foregoing basic engineering before starting work on the project. Cost estimates were not fully verified and proved to be too optimistic. As of the end of December 2012, the company had invested more than $900 million in the project.
