Rudabánya is a mining town with a long and famous history. The settlement is located 50 km north of Miskolc in Northern Hungary and mining has been going on there since times before written history, albeit not without hiatuses of varying durations. Earth pigments, copper, silver and iron ore represent the notable mineral raw materials of the area. Another very interesting feature of the locality is related to significant palaeontological findings in connection with Hominidae. For mineralogists, it is considered one of the archetypal European mineral localities, especially with respect to its secondary copper minerals. Azurite, malachite, native copper, and cuprite specimens from Rudabánya can be found in numerous museums and private collections worldwide.
Throughout the almost 40 years which have passed since the closing of Rudabánya’s commercial iron ore mine, knowledge concerning the complex mineral formations of the area has improved considerably. This is the result of renewed ore prospecting efforts, leading to a better understanding of mineralization phases and parageneses. Alongside such progress, the number of recognized mineral species from the mining site has significantly increased thanks to the thousands of samples gathered by collectors and also due to the work of experts studying these samples.
Only about 40 mineral species were known when the mine was closed in 1985, but by the time of publication of the present book the number of mineral species found and documented at Rudabánya had increased to around 180. Some of the minerals discovered in recent decades are rarities worldwide and these include samples of silver-mercury-sulpho-halides, and silver and copper amalgams. In 2018 rudabányaite was registered as a new mineral species and accordingly received its name after the mining town. With regard to its mineralogical fame, Rudabánya stands out not only for the splendid occurrence of secondary copper minerals but also because of its unique mineral associations.
