The Detour Lake property represents Canada’s largest pure gold mine. Carrying the label of “World Class Asset”, Detour Lake boasts a reserve of 11.4 million ounces, easily exceeding any other single property in the country.
In April 2010, FLSmidth became a major supplier to this project when they were awarded substantial equipment orders for the SAG mills, ball mills, gyratory crusher, cone crushers, and hydrocyclones. With potential orders for thickeners, slurry pumps, and gold recovery equipment, Detour Lake has the potential to be FLSmidth’s largest combined gold project in the history of the company.
Among the world’s largest mills
FLSmidth considers these orders a significant breakthrough for its large grinding mill technology in this part of the world. And “large” is exactly what these mills are. At Ø36’-0” (11m) x 20’-0” (6.1m) long and Ø26’-0” (7.9m) x 40’-6” (12.4m) long these SAG and ball mills (respectively) represent some of the largest gear-driven grinding mills in the world with each featuring 15,000 kW of installed motor power.
The design of this 55,000 tpd grinding circuit centers around two parallel lines, each consisting of one SAG mill followed by one ball mill. The 60” x 113” (1.5m x 2.9m) ultra-duty (UD) primary gyratory crusher with 1,000 kW drive represents the largest machine in FLSmidth’s lineup and will easily feed both lines, even after the scheduled ramp up in production to 61,000 tpd.
Detour Lake is located on the Abitibi Greenstone Belt in northeastern Ontario and is wholly owned by the Detour Gold Corporation – a Canadian gold exploration and development company based in Toronto. FLSmidth will be working closely with BBA Inc. on this project. BBA is the Engineering, Procurement and Construction (EPC) contractor for Detour Lake with home offices located in Montreal. The plans are for the ground-breaking to take place on site later this year, and for gold production to begin in early 2013.
