The mining industry of Guinea was developed during colonial rule. The minerals extracted consisted of iron, gold, diamond, and bauxite. Guinea ranks first in the world in bauxite reserves and 6th in the extraction of high-grade bauxite, the aluminium ore. The mining industry and exports of mining products accounted for 17% of Guinea’s gross domestic product (GDP) in 2010. Mining accounts for over 50% of its exports. The country accounts for 94% of Africa’s mining productioget price

Bauxite The Aluminum Association

ResourcesEnvironmentFutureDiscoveryBauxite ore is the worlds primary source of aluminum. The ore must first be chemically processed to produce alumina (aluminum oxide). Alumina is then smelted using an electrolysis process to produce pure aluminum metal. Bauxite is typically found in topsoil located in various tropical and subtropical regions. The ore is acquired through environmentally responsible strip-mining operations. Bauxite reserves are most plentiful in Africa, Oceania and South America. Reserve
