'bauxitic' originates from French, specifically the word 'bauxite', which itself is named after the village 'Les Baux' in Provence; the English adjective was formed by adding the suffix '-ic' to indicate 'relating to'.

'bauxite' was borrowed from French 'bauxite' (named for 'Les Baux'); English formed 'bauxitic' by attaching the adjectival suffix '-ic' to refer to material related to or composed of bauxite.

Initially it meant 'of or pertaining to bauxite (the ore)', and it has retained that technical meaning in modern usage.
