Lubin

The Lubin mine is the oldest mine in the Polish Copper Belt. The mine extracts polymetallic ore containing mainly copper and silver, and in small amounts, nickel, cobalt and molybdenum.

General Information

The Lubin mine is located in south-west Poland, on the northern border of the town of Lubin, in Lower Silesia. It is the oldest mine in polish Copper Zone. Industrial Resources of Lubin-Małomice deposit (according to state on 31.12.2015) are over 328 million Mg of copper ore. Average copper grade in ore amounts to 1,28% and silver 54,5 g/Mg.

In Lubin-Małomice deposit, there are high grades of silver in addition to copper mineralization, which average grade of Ag in geological resources amounts to 55g/Mg. Dominant lithological type of copper ore are sandstone rocks – nearly 70% of resources.

Lubin-Małomice deposit is characterized by intensive tectonical displacements within orebody, especially in it south-west part - the deposit lays  here in small depth, under loose Cainozoic sediments but with dense grid of faults with big displacements. In areas with such intensive tectonic events exploitation is very hard, in some cases impossible. The depth where copper orebody occurs in Lubin-Małomice deposit range from 368 m up to 1006 m in depth.

History

The team led by Jan Wyżykowski discovered those valuable deposits of copper ore on 23 March 1957. Their discovery held good as a convincing argument to start the construction of Zakłady Górnicze "Lubin" (The Lubin Mining Site) on 1 January 1960.  The mine commenced its operation eight years later and reached its full production capacity of 4.5 million tonnes of ore annually in 1972. After the expansion of the mine a year later, its capacity increased to 7.6 million tonnes of copper ore per year. It continued at that rate until 2012. Year 2013 saw an increase to 7.8 million tonnes with an expected output of 8.0 million tonnes in 2014.

Production

Operations in the Lubin mine are carried out over an area of 158 km2, in three regions: Eastern, Central and Western. The deposit is mined by the room-and-pillar method, using natural roof settlement as well as hydraulic backfill. There are seven shafts from 494 to 963 m deep in the mine. One is an extraction shaft, while the rest are used for material transport and ventilation purposes. The production process comprises preparatory work, access and extraction, and transport of ore from the faces to the surface. The total output of ZG Lubin currently (2015) amounts to 8 ml Mg out of which 68.334 K Mg accounts for copper and 319 Mg for silver.
