3.1.1.1 Historical slags
Historical slags used in this PhD work were collected in the study area representing historical
centre of copper mining and smelting. This site is located in the vicinity of Miedzianka and
Ciechanowice towns in Lower Silesia, (South-western Poland) (Figure 3.1). The beginning of
mining in this historical district is dated on middle ages. The industrial activity developed
there due to occurrence of Cu-rich ores (mainly chalcopyrite with minor bornite and pyrite)
that were exploited at the time. Pollymetalic (Cu, Ag and As-rich) veinlets were formed as the
result of intrusion of granitoid magma (western part of Rudawy Janowickie Mountains) into
the surrounding metamorphic rocks (eastern part of Rudawy Janowickie Mountains) 300-350
million years ago (Variscan Orogeny) (Figure 3.1).
