  • Mining industry of Algeria Wikipedia

    Hydrocarbons are the leading sector in Algeria's mineral industry, which includes diverse but modest production of metals and industrial minerals.In 2006, helium production in Algeria accounted for about 13% of total world output. Hydrocarbons produced in Algeria Mining LKAB,Ore is extracted from LKAB's underground mines by means of sub-level caving. This mining method is based on creating cavities in the orebody through drilling and blasting, and allowing the ore to fall down to underlying levels by means of gravity, from where it is transported onwards by train or loader.
