Get PricePicture 4 shows the distribution of these deposits. About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. The ore is a mixture of minerals and rock (called gangue). The most common copper ...
Get PriceTo date, roughly 700 million metric tons of copper have been produced around the world. This would fit into a cube measuring about 430 meters on a side. Identified deposits contain an estimated 2.1 billion metric tons of additional copper, which brings the total amount of discovered copper to 2.8 billion
Get PriceCopper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

Get PriceAs 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 (i.e. 2% copper and 1.5 gram per tonne gold).
Get PriceIron ore pellets accounted for 29.1% ($1.9 billion) of the volume, and concentrates accounted for the remaining 70.9% ($3.4 billion).. Imports. Canada imported 10.1 million tonnes of iron ore (valued at $1.0 billion) in 2018, up from 8.0 million tonnes in 2017. Most of these imports (98.9%) were in the form of pellets from the United States.
Get PriceThis additional mine area would extend the life of the mine for two years to 2017, allowing the company to continue to explore the area without closing. The additional mining would result in an estimated 4.2 million tons of ore and 52.6 million tons of non-ore rock (waste). What is the percentage of ore to waste (by weight) for these new sections?
