About us

“Central mining sites” in Ljubija are the oldest iron ore mine in the Ljubija metallogenetic area. Production of iron ore in this mine began in 1916. The progress of mining production enabled the construction of infrastructure and production capacities, surface mines, mechanical preparation, wet separation, service workshops.

The projected production capacity is 1.0 million tons of iron ore concentrate per year. The production of iron ore at the “Central mining sites” – Ljubija was suspended in 1992 and has not been started to this day. In the period from 1916 to 1992, 44,643,358 tons of iron ore and concentrate were produced. The buyers of iron ore and concentrate were Yugoslav steel mills and, to a lesser extent, foreign buyers. The exploitation field “Central mining sites” still has about 150,000,000 t of iron ores explored and certified. Four types of iron ores are represented in this locality: limonite, limonite-barite, basic ores (carbonate and oxide) and siderite ores.

At the “Central mining sites” ore preparation and beneficiation facility, it is possible to treat the ore with a dry or wet process, depending on the type of iron ore. The dry process of iron ore preparation consists of three-stage crushing and multi-stage classification, and the final product is aglo ore, size class -10+0 mm. The wet process of iron ore preparation consists of one-stage crushing, washing and classification on sieves, mechanical classifiers and hydrocyclone. The products obtained by the wet preparation process are APR ore, size class -40+10 mm and BPR ore, size class -10+0 mm.

Production of iron ore at the “East mining sites”- Tomašica started in 1965. In 2004, production was suspended and has not been started to this day. In the period from 1965 to 2004, 20,690,037 tons of iron ore were produced. The exploitation field “East mining sites” still has about 35,866,200 t of iron ores explored. In this locality, the limonite-brand iron ore type prevails.

The projected production capacity is 1.2 million tons of iron ore per year. At the “East mining sites” separation plant, iron ore is prepared using a dry process. The preparation consists of one-stage crushing, drying and grading on sieves, which results in products with the trade names AS ore, size class -100+10 mm, and BS ore, size class -10+0 mm.

In the period from 1975 to 1985, work on research and valorization of fine-grained iron ores, brand, as a raw material for the production of natural iron oxides-pigments, was intensified. In 1985, the factory for the production of natural iron oxide-pigments, Ferox, began operating. The projected production capacity of this plant is 10,000 t of iron oxides per year. Work at the factory was suspended in 1992, and to this day the factory has not been revitalized.
