Difference between Ore and Minerals. Minerals are naturally occurring substances of metals present in the earth's crust called minerals. For eg - Clay is a mineral of Aluminium. Ores are those minerals that can be used for the extraction of metal easily and profitably. For eg - Bauxite is an ore of Aluminium.

An ore is a type of rock that contains minerals with important elements including metals.The ores are extracted through mining; these are then refined to extract the valuable element(s).. The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore.The cost of extraction must thus be weighed against the ...
