General Kazakhmys PLC is an international natural resources company, listed in the UK, with its principal operations in Kazakhstan and the surrounding region. The core business is the production and sale of copper.  Kazakhmys is fully integrated from mining ore through to the production of finished metal.  The copper division also produces significant volumes of other metals as by-products, including zinc, silver and gold.

In 2007 Kazakhmys added two new divisions, Kazakhmys Petroleum and Kazakhmys Gold, in keeping with the Group’s strategic aim of diversifying and participating in the development of the significant natural resource opportunities in Central Asia.  MKM is a wholly owned subsidiary, based in Germany, which was acquired in 2004.  MKM produces a range of pre and semi finished copper and copper alloy products.

Kazakhmys is the largest copper producer in Kazakhstan and in the top ten worldwide.  The copper division has operating sites across Kazakhstan with 20 open pit and underground mines, 9 concentrators, a zinc plant and two smelting and refining complexes.  The Group owns coal mines and power plants, which supply sufficient energy for its operations and market excess capacity commercially.

Fully integrated production and good by products, make Kazakhmys one of the lowest cost copper producers in the world.  These advantages, combined with a large reserve base give the Group a strong platform for future growth and development.
