The oolitic brown ores of Lorraine and Luxemburg are known as "minette," a diminutive of the French mine (ore), in allusion to their low content of metal.
Germany gets about two-thirds of her total ore supply from the great Jurassic " Minette " ore deposit of Luxemburg and Lorraine, which reaches also into France and Belgium.
France draws most of her iron ore from her own part of the great Minette ore deposit, and from those parts of it which were taken from her when she lost Alsace and Lorraine.
