Abstract. The term «bauxite» was introduced by Berthier (1821) and refers to rock samples belonging to the laterite type. Lateritic bauxites have been studied by many, mainly by prospection and exploration geologists, and by geologists, soil scientists and geomorphologists interested in the mechanisms of bauxite formation and evolution.

2020.12.15 Today, bauxite is mostly mined in tropical areas like Guinea, Brazil or Australia. Hence, the majority of the bauxite used in Europe is imported, i.e. about 14-15 Mt/year, with the exception of Greece which produces 2 Mt/year used locally. Mining bauxite leads to an impact to land and in usage of raw materials, energy, air emissions and tailings.
