The copper division consists of 20 mining entities with 14 underground mines and 6 open pit mines. The mineral reserves and resources of these mines are sufficient to support projected production for at least 20 years. The mined ore is processed in 10 concentrators and 2 smelters.  The copper division is divided into 4 administrative areas, Zhezkazgan complex, Balkhash complex, Karaganda region and East region.  In addition to producing copper, the division produces significant quantities of zinc, silver and gold, which are sold as by-products.  The division has spare smelting capacity and copper concentrate is purchased, providing additional output.
