Algeria has deposits of iron ore, phosphate, Barite, pozzolana (used in concrete) petroleum, base metals, gold, uranium, Salt, Zinc, Marble, Calcium carbonate, other Industrial minerals including Bentonite, Kaolin, Domestic salt. Currently all mining and exploration activities are being promoted by the Ministry of Energy & Mines which manages 32 mines, 26 quarries and 8 processing plants as well as several suppliers of goods and services to the mining industry.
Algeria's phosphate deposits at Djebel Onk mine, which are among the largest in the world. The mine is located 300 km south of Annaba. The 2400 million tonne Djebel Onk phosphate mine, covering about 2,072 sq km (800 sq mi), with the production of 1 Mt/y of phosphoric acid, together with ammonia.
There are deposits of high-grade iron ore at tonne Quenza, Djebel Onk and Bou Khrada iron ore mines with the 5000 million, near the Tunisian border. Major deposits of medium-grade ore exist at Gara Djebilet near Tindouf. Production totaled 1.65 million tons in 2000, down from 2.25 million tons in 1996; half is exported. The main mining centres are Ouenza and near the eastern border with Tunisia and at El-Abed in the west. Nearly all the high-grade iron ore from the open-cut works at Ouenza is used to supply the domestic steel industry.
Two gold projects in Algeria, are Amesmessa and Tirek, locating in the southern Hoggar region, which are being developed by the South African Council for Mineral Technology. Production was scheduled to begin in 2001. Resource estimates were 4.96 million tons at grade of 14.1 grams per ton gold for Amesmessa, and 1.17 million tons at an average grade of 17 grams per ton for Tirek. Algeria's major mining operations include the 3 million ounce Tirek Amesmessa gold mine.
Several industrial mineral mines produce salt, bentonite and barite. There is limited diamond potential in the Reggane area, which has known alluvial deposits. De Beers have apparantly expressed interest in the kimberlite potential of this region. Among other mineral production in 2000, zinc concentrate output was 10,452 tons, up from 3,690 in 1997; bentonite, 22,708 tons, up from 15,491 in 1999; lead concentrate, 818 tons, down from 1,215 in 1999; mercury, 215,625 kg, down from 447,034 in 1997; crude barite, 51,925 tons, up from 31,348 in 1996; salt, 182,000 tons; hydraulic lime, 96,000 tons, up from 65,000 in 1998; and marble, 700,000 tons. Silver, kaolin, sulfur, fuller's earth, and strontium are also mined.
