Mining and concentrating
Kazakhmys operates 16 underground and open pit mines across Kazakhstan. In 2011, the company mined 33 million tonnes of copper ore, which is processed in our 10 concentrators. Kazakhmys also produces and sells significant quantities of zinc, silver and gold as by-products. Extracting value at every step Kazakhmys is responsible for 90% of all copper produced in Kazakhstan. The company's integrated structure, owning and managing everything from mining to production, has helped make Kazakhmys one of the world's most flexible and lowest-cost copper producers.
Smelting and refining
Kazakhmys operates two smelting and refining plants, which smelt copper concentrate to produce copper plates (anodes). We then send the anodes to our electro-refineries to produce copper cathode with a minimum copper content of 99.95%.
