Extracting value at every step Kazakhmys is responsible for 90% of all copper produced in Kazakhstan. We also produce and sell significant quantities of zinc, silver and gold as by-products. Our integrated structure, owning and managing everything from mining to production, has helped make us one of the world's most flexible and lowest-cost copper producers.
