December 11, China's largest overseas Copper Project - Toromocho copper mine commissioning ceremony was held in Lima, Peru, the world's largest single copper mine beneficiation production line put into operation.

Compared with the same scale Copper Mine Project, Toromocho is the world's Copper Mine Project in the shortest construction period, construction equipment, the highest level of copper resources is Peru's largest mining project. The copper equivalent has about 120,000 tons of copper resources, accounting for China's total domestic copper resources, project design annual production capacity of 220,000 tons of copper concentrate 19% of the more than 30-year design life, will greatly ease China's refined copper mineral resources and supply shortages.

Chinese copper chronic shortage of resources, dependence on foreign resources, up to 80%, and from reserves, the Peru Copper is the world's ninth largest copper mine, has a copper equivalent metal resources of about 12 million tons, equivalent to its reserves fifth Chinese domestic copper reserves, annual production of copper metal scale up to about 250,000 tons, equivalent to one-third of China's annual production of copper concentrate.
