BotEC: Percentage of Copper in Ore Activity Collection
May 09, 2022The copper ore forms only 0.7% of the rock. We need to find a number that we can multiply by .007 to get 90 kg. Dividing 90 kg by .007 will give us that number—approximately 12,860 kg. Multiplying that number by 2.2 pounds/kg would give us the number of pounds (about 28,300 pounds).

The amount of copper in an ore can vary from 0.4 percent to more than 12 percent. Porphyry copper deposits, in which the copper materials are more or less uniformly scattered throughout the rock, account for the greatest tonnage of metal in the producing areas of the world.

Copper Statistics and Information U.S. Geological Survey
Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode. An increasing share of copper is produced from acid leaching of oxidized ores.

Copper Ore an overview ScienceDirect Topics
In most cases, the thin-layer process was used where crushed ores (80% −0.5 in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 Lhour −1 m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.

The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock.

How much copper has been found in the world? USGS
To 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 metric tons. This would fit into a cube measuring 680 meters on a side.

How much metal does the ore contain? ? World Ocean Review
In most cases copper ores contain between 0.6 and 1 per cent of copper. Consequently one tonne of ore generates a maximum 6 to 10 kilograms of copper. In the case of platinum the yield is much lower: 1 tonne of ore usually contains between 3 and 6 grams of platinum. Nonetheless it is still worthwhile mining because the platinum price is high.

Copper Ores
Jun 25, 2013Copper is extracted from copper ore by a series of chemical, physical, and electrochemical processes. Ores can be classed as ‘high grade’ or ‘low grade’ depending on the percentage of copper compounds (e.g. copper carbonate) they contain. After mining, the ore is crushed, roasted, smelted and then electrolysed to extract the copper.
