The Batra mine is a large chromium mine located in central Albania in Dibër County, 40 kilometres (25 mi) east of the capital, Tirana. Batra represents one of the largest chromium reserve in Albania and one of the largest in Europe, having estimated reserves of 0.73 million tonnes of ore grading 38% chromium metal. [1] The mine is part of the Bulqizë Massif, a 370 square kilometres (140 sq mi) area which has a rock thickness between 4 kilometres (2.5 mi) and 6 kilometres (3.7 mi) and contains 65 verified chromium deposits and occurrences. [1] The deposit has been explored to depths of up to 1,560 metres (5,120 ft) and the geological reserves amount to 12 million tonnes of which 7.5 million tonnes grading over 38% chromium metal. [1]

Chromium Chemical element with atomic number 24

Chromium is a chemical element with symbol Cr and atomic number 24. It is the first element in group 6. It is a steely-grey, lustrous, hard and brittle transition metal. Chromium boasts a high usage rate as a metal that is able to be highly polished while resisting tarnishing. Chromium is also the main additive in stainless steel, a popular steel alloy due to its uncommonly high specular reflection. Simple polished chromium reflects almost 70% of the visible spectrum, with almost 90% of infrared light being reflected. The name of the element is derived from the Greek word χρῶμα, chrōma, meaning color, because many chromium compounds are intensely colored.

Albania country in Southeast Europe

Albania, officially the Republic of Albania, is a country in Southeast Europe on the Adriatic and Ionian Sea within the Mediterranean Sea. It shares land borders with Montenegro to the northwest, Kosovo to the northeast, North Macedonia to the east, Greece to the south and a maritime border with Italy to the west.

Dibër County is one of the 12 counties of the Republic of Albania, spanning a surface area of 2,586 square kilometres (998 sq mi) with the capital in Peshkopi. The county borders on the counties of Durrës, Elbasan, Kukës, Lezhë, Tirana and the country of North Macedonia. It is divided into four municipalities, including Bulqizë, Dibër, Klos and Mat.. The municipalities are further subdivided into 290 towns and villages in total.

The Batra mine began operating in 1967. Between 1964 and 1967 it produced chromium ore only from occurrences. [1] In 1967 production from the mine started. The total combined chromium ore production from the mine between 1967 and 2006 amounted to 5,561,000 tonnes. [1] The deepest level of the mine is the Level +1560 which reaches a depth of 1,560 metres (5,120 ft). The chromium ore reserves of the mine are split into two categories above and below Level +1560. The proven ore reserves located above the Level +1560 amount to 730,000 tonnes of ore grading 38% chromium metal. [1] The proven ore reserves located below the Level +1560 are currently not estimated or calculated but are expected to be grading 45% chromium metal. [1] The mine was privatised in 1999.

Ore rock with valuable metals, minerals and elements

An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted from the earth through mining; they are then refined to extract the valuable element, or elements.

Mining The extraction of valuable minerals or other geological materials from the earth

Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, lode, vein, seam, reef or placer deposit. These deposits form a mineralized package that is of economic interest to the miner.
