Two main Kupferschiefer mining areas in Poland are the North-Sudetic trough, with 212,894 tonnes of copper and 756.7 tonnes of silver mined as of 2012 and an estimated remaining reserves of 1,460,000 tonnes of copper, and the Fore-Sudetic monocline, with more than 20,000,000 tonnes of copper and more than 14,085 tonnes of silver mined since 1949.
The copper ore deposit operated by KGHM in Poland dips monoclinally at the depth from a few hundred meters to 1500 meters. Copper minerals are hosted by three main lithological rock types: sandstone, shale and dolomite. Four base copper sulphides are most common in the ore: chalcocite, bornite, chalcopyrite and covellite.
The copper sulfide ore from the Legnica-Glogow Copper Basin in Poland, which is processed by KGHM Polska Miedz S.A., consists of three lithological fractions: dolomitic, sandstone and shale. The copper ore, depending on the mining area, contains all fractions in different ratios.

According to the latest data (Kubacz and Skorupska, 2007) the content of shale fraction in Lubin copper deposit has already reached 27 % and became the major problem in effective ore processing. The content of shale in Polish copper ores has almost doubled within last four years. Almost 64 % of all valuable metals and 60 % of
Poland, the Lubin ore deposit which is currently being exploited belongs to this type of geological formation and evaluation of potentially more efficient and environmentally sensitive processing routes is of strategic importance for the Polish copper industry. In Finland at Talvivaara, the potential exploitation of
In Poland shale is present in Silurian sediments, i.e. they are placed between 2,5 up to 4km beneath the surface. It means that in Poland the technology of resource extraction is more complicated.
Jun 12, 2013· Poland’s leaders quickly made shale gas exploration a priority, voicing ambitions that the country could surpass its own domestic requirements and becoming a gas exporter. Policymakers had high hopes that shale gas would provide Poland with a boost to its slowing economy and help reduce its high unemployment rate, currently around 14 percent.
Jan 01, 2008· In Poland, the Lubin ore deposit which is currently being exploited belongs to this type of geological formation and evaluation of potentially more efficient and environmentally sensitive processing routes is of strategic importance for the Polish copper industry.
Keywords: flotation frothers, copper shale, critical coalescence concentration 1. INTRODUCTION Copper-bearing shale, also called European Permian black shale or Kupferschiefier [1, 2] is a part the copper ore currently mined in Poland in the Legnica-Glogow Copper Basin area [3]. The shale forms a

concentrates and black shale ores from Poland. Key words: bioleaching, biotechnology, mineral processing INTRODUCTION The natural ability of microbes to degrade minerals was already used in the Roman times for copper recovery, without awareness of the role of micro-organisms. In the

The content of shale in Polish copper ores has almost doubled within last four years. Almost 64 % of all valuable metals and 60 % of
Copper ores processed in Poland are the mixtures of three lithological types: calcium and In the Polkowice processing plant, in turn, carbonate is the predominant ore type, of copper ore (carbonate, sandstone, and shale ore) were manually divided within each particle size fraction (Figure1).
The copper sulfide ore from the Legnica-Glogow Copper Basin in Poland, which is processed by KGHM Polska Miedz S.A., consists of three lithological fractions: dolomitic, sandstone and shale. The copper ore, depending on the mining area, contains all fractions in different ratios.

The copper production quantity was 66.9 kt. Silver, gold and lead are obtained there as byproducts. The existing silver reserves of the Lubin mine amount to 17 883 t, while all three mines in Poland have total reserves of almost 70 000 t, which corresponds to a lifetime of approx. 58 years.
Aurubis is the largest copper producer in Europe and is the global leader in copper recycling. It produces some 1 Mt/y of copper cathodes and more than 1.2 Mt/y of copper products per annum. It has about 4,800 employees at 12 production sites in seven European countries (Germany, Belgium, Bulgaria, Italy, Switzerland, Great Britain and Slovakia).
Nov 17, 2015· The context. European deposits of black shale ores contain considerable reserves of base and highly valuable rare and precious metals (Cu, Ni, Zn, Pb, Ag, Zn, Co, Mo, Re, V, Se, Sn, Bi, Au, Pt, Pd, etc.) of which Europe is the main consumer in the World, so availability assumes a
laboratory flotation machine. A sample of carbonaceous copper shale originated from the Kupferschiefer stratiform copper deposit (Fore-Sudetic Monocline copper ore) located in SW Poland. The advancing and receding contact angles for the investigated shale/water/air system was 42º and 24º, respectively (Bednarek, 2014). Seventy grams
Aug 01, 2018· The copper contents of the sandstone and black shale fractions used in the current experiments were similar, though in most kupferschiefer strata the copper content of the thinner black shale layer is generally much greater than that of the thicker sandstone layers. In addition, sandstone was more readily leached, both with acid and acidic
