Ore is rock that contains economic amounts of a particular element, eg gold ore, iron ore, molybdenum ore, or praseodimium ore In contrast, rock that is not judged to contain economic quantities of an element is categorized as waste rock The metals in ore can occur in many different minerals (compounds) in the rock As an example, ,
Concentration includes all the processes that will increase (upgrade) the iron content of an ore by removing impuriti Beneficiation, a slightly broader term, includes these processes as well as those that make an ore more usable by improving its physical properties (eg pelletising and sintering)
Regardless of its setting, hematite is usually found with other iron-bearing minerals, especially magnetite, goethite and siderite In Early Proterozoic (25 to 16 billion year ago) iron ore deposits, layers of hematite and other iron oxides alternate with bands of chert (microcrystalline quartz) to form distinctively layered deposits known as .
