Joint venture Bauxit mines and alumina operations in historic Northwest Guinea about 80% of Guinea`s foreign exchange. The bauxite is refined into alumina, which is then melted into aluminum. The Guinea Bauxite Company (CBG), which exports about 14 million tonnes of high-quality bauxite per year, is the main player in the bauxite industry. CBG is a joint venture 49% owned by the Guinean government and 51% by an international consortium called Halco Mining Inc., itself a joint venture controlled by aluminum producer Alcoa (AA), global miner Rio Tinto Group and Dadco Investments.  The CBG has exclusive rights to bauxite reserves and resources in northwestern Guinea until 2038.  In 2008, protesters who were energizing about poor power supplies blocked the tracks the CBG uses.

Tribes is a step-by-step process to achieve specific learning goals.
Four agreements are respected: in 2014, the Ebola virus broke out in Guinea. In response, the Ministry of Health prohibits the sale and consumption of bats, designed to carry the disease. Despite this measure, the virus eventually spread from rural areas to Conakry and spread to neighbouring Sierra Leone and Liberia in late June 2014. In early August 2014, Guinea closed its borders with Sierra Leone and Liberia to limit the spread of the virus, as there were more reported new cases of the disease in these countries than in Guinea.
