'aluminum-ore-bearing' is a compound formed from the modern English elements 'aluminum' + 'ore' + 'bearing'. 'aluminum' (the modern U.S. form) ultimately derives from New Latin/Latin roots related to 'alumen' meaning 'alum' (a substance containing aluminum salts). 'ore' comes from Old English and Germanic roots for a mineral deposit, and 'bearing' comes from the verb 'to bear' (to carry, contain).

'aluminum' was coined/adapted in the early 19th century (variants include 'alumium', 'aluminium' and later U.S. 'aluminum'); 'ore' comes from Old English 'ōra' (or related Germanic forms); 'bearing' comes from Old English 'beran' ('to carry'). These parts combined in modern English to form descriptive compounds like 'aluminum-ore-bearing'.

Initially, Latin 'alumen' referred specifically to 'alum' (a salt), and 'ore' referred broadly to mineral deposits; over time 'aluminum' came to name the element/metal and related ores (e.g., bauxite), so the compound evolved to mean 'containing deposits of aluminum ore' in current usage.
