Rock that contains utilitarian materials; primarily a rock containing metals or gems which -- at the time of the rock's evaluation and proposal for extraction -- are able to be separated from its neighboring minerals and processed at a cost that does not exceed those materials' present-day economic values
A natural mineral compound of the elements of which one at least is a metal (e g , copper, lead, molybdenum, zinc, gold) The term is applied more loosely to all metalliferous rock and occasionally to the compounds of nonmetallic substances and industrial minerals such as, sulphur ore In economic terms, an ore is a mineral of sufficient value as to quality and quantity that it may be mined at a profit
A natural aggregate of one or more minerals that can be mined and profitably sold under current conditions, or from which one or more minerals can be profitably extracted
A native mineral containing a precious or useful metal or metalliferous minerals in such quantities and in such chemical combination as to make its extraction profitable or a mixture of valuable ore minerals and gangue from which at least one of the metals can be extracted for profit
Ore is rock or earth from which metal can be obtained. a huge iron ore mine. Oregon. A mineral or an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined or extracted. rock or earth from which metal can be obtained. Aggregate of economically important minerals that is sufficiently rich to separate for a profit. Although more than 3,500 mineral species are known, only about 100 are considered ore minerals. The term originally applied only to metallic minerals (see native element) but now includes such nonmetallic substances as sulfur, calcium fluoride (fluorite), and barium sulfate (barite). Ore is always mixed with unwanted rocks and minerals, known collectively as gangue. The ore and the gangue are mined together and then separated. The desired element is then extracted from the ore. The metal may be still further refined (purified) or alloyed with other metals. magnetic iron ore bog iron ore hydrothermal ore deposit ore dressing
Material extracted from the Earth's lithosphere that yields metallic minerals An ore normally has two parts: the metallic mineral and waste mineral material commonly called gangue
Valuable (usually metallic) minerals that can be mined profitably Overburden: Unconsolidated rock, clay, etc Oxygen: Colourless odourless gas present in many minerals
body of rock or a deposit of sediment that is worth mining for the economically valuable mineral it contains The term is usually applied to sources of metals
An ore is a material that contains a metal in such quantities that it can be mined and worked commercially to extract that metal The metal is usually contained in chemical combination with some other element in addition to various impurities
The mineral or aggregate of minerals from which a valuable component can be removed at a profit Workers remove ore deposits from the earths crust through mining or quarrying and then separate the useful portion from the useless mass
A kind of rock made up of different minerals that might contain useful metals, such as gold, iron, or silver If there are useful metals in the rock, it is crushed and the metals are taken out using heat, electricity or chemicals
