Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite, boehmite and diaspore, mixed with the two iron oxides goethite and haematite, the aluminium clay mineral kaolinite and small amounts of anatase and ilmenite . Bauxite appears dull in luster and is reddish-brown, white, or tan.

The economy of Guinea is dependent largely on agriculture and other rural activities. Guinea is richly endowed with good minerals, possessing an estimated quarter of the world's proven reserves of bauxite, more than 1.8 billion tonnes of high-grade iron ore, significant diamond and gold deposits, and undetermined quantities of uranium. In 2021, Guinea was the world's biggest exporter of Aluminium Ore 2021 trade surplus was $4.3B.
Transport in Guinea is composed by a variety of systems that people in the country use to get around as well as to and from domestic and international destinations. The railway from Conakry to Kankan ceased operating in the mid-1980s. Most vehicles in Guinea are 20+ years old, and cabs are any four-door vehicle which the owner has designated as being for hire.

The majority of Vietnam's reserves are located in the Central Highlands and have only been minimally mined. Bauxite is typically strip mined and is used to produce aluminum. According to estimates by Vietnam's Ministry of Industry and Trade, Vietnam's reserves in the Central Highlands amount to 5.4 billion tons. Despite its large reserves, Vietnam produces only 30,000 tons of bauxite per year.
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.
