NEW ZEALAND - The world's largest flotation cells, TankCells built by OUTOTEC of Finland, have been commissioned at the Macraes gold project on the South Island. The project is owned by OCEANAGOLD of Melbourne, Australia.
The new installation of three 300-m tanks combined with existing Outotec 150- m tanks has successfully replaced the two original trains of column and conventional flotation cells. This represents a significant reduction in process plant footprint and the upgrade is expected to reduce maintenance and operating costs, according to OceanaGold.
The Macraes plant produces an average of 180,000 oz of gold per year by treating ore from the company's Macraes, Frasers and Reefton mines in New Zealand. See www.OceanaGold.com.au for details.
