THe question seems wrong . It should be that Why all minerals are not ores ?
Those substances which occurs naturally in the Earth's crust are called Minerals .And minerals which can be extracted from the Earth's crust profitably is called ores . Therefore all ores are minerals . Metals with high concentration can be acheived profitably but  not all minerals. 
Therefore all minerals are not ores.

All ore are mineral but all minerals are not ore because 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)
