NATIONAL URANIUM COMPANY BUCHAREST ROMANIA

2015-10-22  Around 1950 uranium exploration was subject of a joint venture between the Soviet Union and the National Uranium Company. Large geological surveys were performed in the south-western (Banat county) and north-western (Bihor county) regions of Romania. In 1952 uranium mining commenced as an open-pit excavation, in the Bihor region (BăiţaPlai).

Uranium Mining and Milling Uranium production. Uranium occurs with an abundance of 2.7 parts per million by weight in the Earth's crust. It is 600 times more abundant than gold and about as abundant as tin which makes it a rather common metal. Traces of it occur almost everywhere: in most rocks and solids, in many rivers and sea water.
