'bauxite-containing' originates from English, specifically the word 'bauxite' combined with the present-participle/adjective-forming 'containing', where 'bauxite' comes from French 'bauxite' (named after the village 'Les Baux') and the suffix '-ite' originally meant 'stone', and 'containing' ultimately derives from Latin 'continere' ('con-' = 'together' and 'tenere' = 'to hold').

'bauxite-containing' developed as a modern English compound by joining the mineral name 'bauxite' (from French 'bauxite', named after Les Baux) with the English participle/adjective 'containing' to describe materials or deposits that hold bauxite.

Initially it simply described something 'containing bauxite'; over time the phrase has remained stable in meaning and is used primarily in geological and industrial contexts to indicate the presence of bauxite.
