Operations have been ongoing for nearly 150 years in this copper mining district. Its operation nearly doubled its production capacity during World War II at the urging of the U.S. government to meet wartime needs. It is now North America's largest producer of copper, and the world's largest producer of copper cathode from the solvent extraction-electrowinning process.
As part of a major mining and milling expansion to process additional sulfide ore, TNT engineered and supplied 15 new in-plant conveyors and modifications to three existing conveyors, including all mechanical, structural and instrumentation. These conveyors range from 54” to 96” wide, totaling 12,500 feet in length and 6,000 tons of steel.
TNT also supplied 18” and 24” grinding-ball handling conveyors, two 54” concentrate belt feeders and a 24” concentrate conveyor complete with custom-designed sampling system.
