Archaeological evidence shows that mining in the area dates back to the Bronze Age (1900 - 1700 BC). The main ore exploited in those times was native copper from the oxidation zone of the deposit. Later on, iron ores brought about a gradual switch from copper to iron mining.
Mining was an activity of the Dacians, the ancient inhabitants of present day Romania. After the Roman conquest in 106, mining was expanded in the Roman province of Dacia. At Berzovis (present day Berzovia, ten kilometres northwest of Ocna de Fier) a Roman metallurgy school, Schola fabrorum, was established, showing the keen interest the Romans had in metal extraction. At Cracul cu Aur (= "Golden Hill" in Romanian), north of Ocna de Fier, old Roman gold mining galleries can still be seen. They look like the much better preserved ones at Rosia Montana ("Verespatak"), in the Apuseni Mountains.
The Constantin Gruescu Iron Aesthetic Mineralogy Museum is located in Ocna de Fier.
