  Rezumat:  The Gyöngyösoroszi lead-zinc mine was once a 150,000 tonne/year underground facility. The combined historic production since 1952 until its suspension was 3,6 M tonnes of low-grade vein type Pb-Zn ore. The mining stopped in 1986, and provisional mine-water treatment facilities have controlled its ARD-producing mine water before entering into the natural drainage. Several surface installations – like the 2,1 million tonnes tailing pond – remained unprotected and impose considerable environmental hazard. Recent efforts aiming to reduce or eliminate these hazards and finding a cost-effective long-term solution are summarized. The mine water geochemistry and treatment methods, the present status of the tailing material is shown.
