A farewell to the shaft furnaces

On July the 16th, 2016, the Głogów Copper Smelter/Refinery extinguished its shaft furnaces. Thus ended 45 years of the shaft technology era at the facility, which will be replaced by a flash furnace, marking a turning point in the history of Polish metallurgy.

“It's like getting out of an old Opel and getting into the latest model Mercedes,” Piotr Walczak, Vice-President of KGHM Polska Miedź for production, explained. “Economic and environmental reasons stood behind our decision to implement the new technology. I hope it will start beating like the second heart of our facility in October.”

Reporters and employees took part in the celebrations marking the phasing out of the old furnaces. Sirens marked the moment when copper ingots stopped flowing into the furnace.

“On July the 17th, 1971, the first shaft furnace was ignited. Today the last one is being shut down. It was a truly emotional moment for all those who have spent many years here and who are also present here today,” Zbigniew Gostyński, Production Manager at KGHM Polska Miedź, commented.

As of October, 2016, production at the Głogów 1 Copper Smelter/Refinery will be based on one-stage flash furnace smelting technology. Blister copper will be produced directly from dried concentrate. This technology combines the three stages of concentrate roasting, smelting matte and converting into a single process.

The investment in flash furnace technology is an essential element of the Pyrometallurgy Modernisation Program, which has been carried out in KGHM Polska Miedź since 2010. It will enable an increase in production through the use of the best and most cost-efficient technologies. It also eliminates environmental risks. Flash furnace technology is one of the most modern in the world. Its implementation in the Głogów 1 Copper Smelter/Refinery puts Polish metallurgy among the world’s top producers, guaranteeing the reduction of processing costs and more efficient recovery of valuable associated metals (by-products of copper smelting).
