3. what is mineral ore used for? ans: ore is a deposit of one or more precious minerals in the earth’s crust. the most important ore deposits such as copper silver and iron contain metals that are essential to industry and trade. copper ore is mined for a wide range of industrial applications.

Apr 23 2011 sulfide copper ores are the most profitable ores because they have high copper content and the copper can be more easily separated from the unwanted minerals. it is important to note that sulfide ...
At first glance sustainability and mineral resource development appear to be in conflict. mining depletes finite resources and in a strict sense therefore is inherently unsustainable. for instance there is only a finite amount of copper in the earth’s crust and each unit of copper extracted ...
Copper is mined and extracted from copper ores. to extract the metal from the ore the rock is melted at a temperature greater than 900 c which requires a lot of energy. extracting metal from rock is so energy intensive that if you recycle just 40 aluminum cans you will save the energy equivalent of one gallon of gasoline.
Copper is most commonly present in the earth’s crust as copper-iron-sulphide and copper sulphide minerals for example chalcopyrite cufes2 bornite cu5fes4 and chalcocite cu2s.
Copper ores and concentrates copper content 2603.00.0010 1.7 kg on lead content. unrefined copper anodes 7402.00.0000 free. refined copper and alloys unwrought 7403.00.0000 1.0 ad val.
Copper ores. an ore is a rock containing enough valuable mineral to make it worth extracting. in the case of copper it is worth extracting when there is about 2 kg of copper per 1000 kg of ore 0.2. copper minerals are found in over one hundred varieties although only a few have been worked for copper on a large scale.
Copper ores. collectable copper ores and minerals. this is a selection of the most commonly collected copper ores. also included are a few other interesting ores of metals often alloyed with copper such as zinc lead and bismuth. illustrations are being added where available.
Even though native copper is sometimes mined on its own for the copper content. chat online; list of copper oreswikipedia. following is a list of minerals that serve as copper ores in the copper mining process name formula copper when pure copper when pure copper-bearing minerals last edited on 2 june 2020 at 09 19.
Geologic occurrence. azurite is a secondary mineral that usually forms when carbon-dioxide-laden waters descend into the earth and react with subsurface copper ores. the carbonic acid of these waters dissolves small amounts of copper from the ore. the dissolved copper is transported with the water until it reaches a new geochemical environment.

Ore minerals. the copper deposits of the white pine mine are large stratiform deposits in the nonesuch shale of upper precambrian age. the ore is typically finely disseminated barely seen in the shale. copper concentrations average 1-2 copper. higher grade zones occur in open fractures from a second pulse of mineralization and the copper can ...
Place these products in the extraction process in ascending order of copper content. use the flow chart as a guide: matte ore cathode copper blister anode copper copper concentrate fire refined copper; use a periodic table to find the atomic masses of the elements in cuprite and chalcocite. then work out the percentage of copper in each mineral.
Properties of copper ores the problem minerals from which copper can be extracted to make money are called copper ores. there are several copper ores but they all fall into two main categories: oxide ores and sulfide ores. oxide ores contain oxygen. sulfide ores contain sulfur. azurite malachite and chrysocolla are a few examples of oxides ores.

Samples of copper ore such as malachite could be shown if available. for the second question work out the concentration of copper in say test-tube 3: concentration cu as cu 2 410 x 1 m 0.4 m. work out the concentration of copper ions when 5 g of copper carbonate is dissolved and made up to 100 cm 3 of solution: formula mass of ...
Separation of special copper ores such as those containing molybdenite or with high zinc or lead content canada is also possible by flotation methods. flotation of non-sulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper
Sulfide ores are more important commercially. half of the world's copper deposits are in the form of chalcopyrite ore. ores are removed either by open-pit or by underground mining. ores containing as little as .15 copper can be mined profitably in open-pit mining but underground mining is profitable only if an ore contains 6 to 7 copper.
That is because they have high copper content and the copper in them can more easily be separated from unwanted minerals. however copper oxide ores have
The average grade of copper ores in the 21st century is below 0.6 percent copper with the proportion of ore minerals being less than 2 percent of the total volume of the ore rock.
The concentration of a mineral in the ore body i.e. or gt 2 copper and 1.5 gram per tonne gold: strike length: the length in which the mineralization is found in the ore body horizontally 500 meters: depth: the depth in which the mineralization is found in the ore body vertically 200 meters: width
The milpillas mine is a huge underground excavation which mines a manto deposit of the copper-rich mineral chalcocite. manto orebodies are irregular to rod-shaped ore occurrences which usually occur in horizontal layers. the orebody is covered by 800 to 2400 feet 250-720m of gravels.
World primary and secondary production of refined copper was 8.825 mt in 1992. ore processing smelting and refining copper minerals are separated from ores mainly by the process of froth flotation. the ore 0.5–2 cu is crushed and ground to produce a fine suspension in water which is passed through a series of flotation cells. air jets ...
