Precious metals

Precious metals, due to their rarity and unique physical and chemical properties, are the most precious and most widely explored natural resources in the history of civilisation. In the copper production process, KGHM also obtains precious metals, like: silver, gold, palladium and platinum. 

General information

Silver and gold have always had a permanent value. Due to its unique properties, silver is widely used both in industry and for investments. It is applied in jewellery, numismatics, electronics, photography, medicine and production of cutlery. As far as gold is concerned, as much as 90% of world production is treated as investment and jewellery gold, and only 10% is applied in industries. The majority of palladium and platinum production is utilized by automotive, chemical and electronics industry.

Production

KGHM is the world the biggest producer in metallic silver. The company produces around 1200 tonnes of this precious metal a year. Cathode silver, with more than 99.99 Ag content (so called, four nines), is produced in the form of bars (gąska) weighing 1000 of troy ounce (32,15 kg) and granules. The silver in the form of bars is registered under the KGHM HG Brand and has the certificate of being listed at NYMEX, New York Mercantile Exchange as well as the “Good Delivery” certificate issued by the London Bullion Market Association.

99,95% Au pure gold is recovered from gold-bearing slime obtained during the process of electrolytic silver refining and sold in the form of bars. Once the recovery process is complete, small amounts of rich platinum and palladium concentrate are left which are then delivered to other refineries. Yearly, KGHM produces 3 thousand ounces of palladium and platinum.

The "Głogów" Copper Smelter holds certificates of compliance with the Integrated Management System as regards its production of round billets and granules from electrolytic silver and its gold production. The company fully implements the guidelines laid down in EN ISO 9001:2008, EN ISO 14001:2004 and BS OHSAS 18001:2007.
