The concentration of a mineral in the ore body ( % or g/t) 2% copper and 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 width in which the mineralization is found in a drill hole: 100 meters: Specific
When bioleaching is complete, 80 to 90 percent of copper has been extracted from the ore. The process can be used on ores that are only to one percent copper, too little for conventional refining. The solution is then drained in to an electrolytic cell and copper extracted from it. In addition, studies show that zinc, nickel and cobalt can also largely be extracted by the process of
The largest mass of elemental copper discovered weighed 420 tonnes and was found in 1857 on the Keweenaw Peninsula in Michigan, US. only a tiny fraction of these reserves is economically viable with presentday prices and technologies. Estimates of copper reserves available for mining vary from 25 to 60 years, depending on core assumptions such as the growth rate. Recycling is a major
transportation to render mining a viable the surface rock and dig out the ore) two percent copper, could be economically feasible when #187; More detailed! Gold: The Element. Sep 26, 2011 #183; Its atomic mass is amu. Harvesting sea to obtain gold is not economically viable, more than 95 percent of gold extraction is
Ore, a natural aggregation of one or more minerals that can be mined, processed, and sold at a profit. An older definition restricted usage of the word ore to metallic mineral deposits, but the term has expanded in some instances to include nonmetallics. Although more than 2,800 mineral species
Jackling demonstrated that the mining of lowgrade ores, containing only two percent copper, could be economically feasible when mined and processed in mass production. Jackling also utilized new methods of metallurgical extraction, primarily those involving an improved flotation process for the concentrating of lowgrade ores. (quot;Concentratingquot; is the process of separation of copper minerals
Answer. A block weighing about 12,860 kg (almost 28,300 pounds, or over 14 tons)!! The copper ore forms only % of the rock. We need to find a number that we can multiply by .007 to get 90 kg.

24/03/2017#0183;#32;As a rule of thumb, open pit mining can process ore for 10 per tonne and, where the ore grade is more than double that at 20 per tonne, results would be economic
This is not enough to make it commercially viable to extract the rock. Copper mines are only set up where there is more than 5kg of copper per tonne of rock (% by mass). Ideally, the figure should be closer to 2%. The flow chart shows you how copper is extracted from its ore and converted into pure metal.
