Metals above carbon in the reactivity series must be extracted using electrolysis metals less reactive than carbon can be extracted from their ores by reduction copper silver gold and platinum can occur native and do not need to be extracted sometimes cop,How Many Ppm Does Copper Ore Have To Be To Be Valuable.

Nov 22 2018 iran copper ore conveyor products and the songun copper deposit has 1 billion tons of copper ore with an average 070 percent copper and 50 ppm molybdenum a boehmite or a copper ore beneficiation plant copper ore a valuable mineral source for all countri copper ore is an ore which can produce copper gypsum mining equipmentChat Online
Oct 21 2015 thanks guys like i saiid i am new to dredging and all of your comments make sense i also have to thank you for the references i have some more research to do there is never enough hours in the day we had thought about a bolt thru the nozzle to lmit the size of rock we are trying to push thrChat Online
Copper ore price the page provides a list of copper ore and concentrate selling and purchasing offers the proposals related to copper commodity and copper ore of different grades of purity and volume of supply from various countries the information on copper ore international price copper concentrate price per ton could be foundChat Online
high concentrations of uranium 10 ppm occur in many types of intrusive igneous rocks generally the uranium content of large igneous bodies does not exceed 20 ppm however the last part of the intrusion to crystallize may show significant enrichment of uranium inChat Online
The minimum concentration of silver should be above an average of 30 ppm gt to be recovered as bye product the producible concentration of silver or optimum grade may be very different on types of ore deposits precious metals such as au ag cu ect can beChat Online
Looking at copper for example we can see that while average rock has around 40 ppm parts per million of copper a grade of around 10000 ppm or 1 is necessary to make a viable copper deposit in other words copper ore has about 250 times as much copper as typical rockChat Online
Copper is found alongside many other types of ore it can be found near gold silver zinc lead and other types of metal deposits when mixed in with other ores copper is not usually found in great abundance until the development of the modern copper mining process it was typically a byproduct of mining for other metalsChat Online
high concentrations of uranium 10 ppm occur in many types of intrusive igneous rocks generally the uranium content of large igneous bodies does not exceed 20 ppm however the last part of the intrusion to crystallize may show significant enrichment ofChat Online
Mountain groundwater sinks down into crust and follows a curving path that eventually brings it back to the surface somewhere below the temperatures reached by the groundwate dissolves metals when the water returns to the surface and enters cooler rock the metals precipitate in ore mineralsChat Online
As you can see in the example above the deposit does not have to be enormous in size only 500 meters long by 100 meters wide to contain a valuable deposit approximately 6 billion worth of minerals however in order to be as realistic as possible about this valuation you can not assume that the complete ore body contains the same grade ie 2 copper and 15 gram per tonne goldChat Online
If you cant grow it then it has to be mined and many types of ore are needed in our world for us to live the way we do from the metals which give high strength steel its tenacity to those which enable the view screens on our computers these ores must be made available or we go back to living like it was the dark ages all over againChat Online
1943 copper lincoln penny is one of the most soughtafter coinsabout 40 have been found that year the us mint switched to making pennies from zinccoated steel instead of 95 copper5 zinc and tin but by mistake some copper pennies still were made and those may be worth 25000 to 100000 or even 2 million in pristine conditionChat Online

Copper mining and processing processing of copper ores copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 9999 pure copper called cathodes which will ultimately be made into products for everyday useChat Online
Tin sources and trade in ancient times tin is a relatively rare element in the earths crust with about 2 parts per million ppm compared to iron with 50000 ppm copper with 70 ppm lead with 16 ppm arsenic with 5 ppm silver with 01 ppm and gold with 0005 ppm valera valera 2003 p 10Chat Online
Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals with the remainder of the ore being unwanted rock or gangue minerals typically silicate minerals or oxide minerals for which there is often no value in some cases tailings have been retreated to recover lost value as the technology for recovering copper has improvedChat Online
The upper 10 kilometers of the crust is thought to contain an average of about 33 ppm of copper for commercial exploitation copper deposits generally need to be in excess of 05 copper and preferably over 2 the known reserves of highergrade ore in the world amount to nearly 1 billion tons of copperChat Online
Typical mines today have ore grades of only 06 percent copper since metal concentrations occur at much lower grades the copper concentrations are measured in parts per million ppm if a sample has 1ppm copper this means that in 1 million lbs of rock there is 1 lb of copper 4Chat Online
The scrap copper melt value calculator shown below can figure the total copper value of scrap copper items measured by the weight unit of your choice the copper value is figured based on the total amount of actual copper content not including any other metals used if it is an alloyChat Online
Dec 10 2019 the copper in a penny a pre1982 copper penny contains about 295 grams of copper and there are 45359 grams in a pound the price of copper in june 2016 was 217 a pound which made the value of copper in each penny worth about 14 cents the meltdown value of a penny was 40 percent more than the face valueChat Online
An ore deposit will consist of ore minerals that contain the valuable substance gangue minerals are minerals that occur in the deposit but do not contain the valuable substance since economics is what controls the grade or concentration of the substance in a deposit that makes the deposit profitable to mine different substances requireChat Online
If you have 6 tons of ore thats a lot of ore and you have a lot of hard work ahead of you if want the ounce of gold disbursed in it it will take time and energy to win the metal and it mightChat Online
The goal of assaying and testing any potential gold and silver bearing materials is to determine their metals content while it is sometimes possible to look at a sample and guess its possibilities more often than not in order to have an accurate idea of how valuable in ore is it must be analyzedChat Online
There are many types of copper ore found throughout the world picture 4 shows the distribution of these deposits about 80 of all copper extracted comes from sulphide ores a typical ore contains only 05 to 20 copper it is a measure of the value of copper that itChat Online
