For many years, KGHM has held a high position among the world's leading silver producers. We were also ranked 1st/2nd in the World Silver Survey last year. In turn, last week the portal dedicated to investors Kitco.com reported that KGHM Polska Miedź is the first silver producer in the world.
KGHM sells this precious metal in the form of bars and granules and is one of the largest producers of silver metal. Silver is supplied in granulated form to factories producing materials for jewellery and metal works producing Ag-containing alloys. Silver in the form of bars goes mainly to financial institutions.
Silver production at KGHM
The production of silver at KGHM takes place at Głogów smelter, where there has been a Precious Metals Division since 1993. It was created specifically to recover the precious metals, silver and gold, present in the copper ore. These are found in the so-called 'black mud', or anode slime, produced during the electrorefining of copper. From cathode silver with an Ag content of more than 99.99 per cent, metallic silver is produced in the form of granules packaged in 25 kg bags and bars weighing approximately 1,000 troy ounces, which amounts to approximately 31.1 kg.
