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
Rock, generally containing metallic and non-metallic minerals that can be mined and processed at a profit
Rock that can be mined for extraction of a mineral commodity under conditions that allow a profit to be made
a monetary subunit in Denmark and Norway and Sweden; 100 ore equal 1 krona a metal-bearing mineral valuable enough to be mined
A native metal or its compound with the rock in which it occurs, after it has been picked over to throw out what is worthless
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
material that contains one or more minerals, at least one of which can be recovered at a 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
(Osmanlı Dönemi) Fls: Varlığı kendinden olan, var olmak için kendi dışında başka birşeye muhtaç olmayan varlık. Allah'a inanan filozoflar iki çeşit cevher kabul etmişlerdir. Yaratıcı cevher, Allah.
