BotEC: Percentage of Copper in Ore

Mar 14, 2021 The 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).

Copper Mining and Extraction Sulfide Ores

Copper mines are only set up where there is more than 5 kg of copper per tonne of rock (0.5% by mass). Ideally, the figure should be closer to 2%. The world’s largest copper ore deposits are found in Chile on the west coast of South America. This is due to the volcanic activity that is part of the process that created the Andes mountain chain.

Infographic: Visualizing Copper's Global Supply Chain

Nov 20, 2020 Copper-containing rock or ore only has a small percentage of copper. Most of the rock is uneconomic material, known as gangue. There are two main copper ore types in mining: copper oxide ores and copper sulfide ores. Both ore types can be economic, however, the most common source of copper ore is the sulfide ore mineral chalcopyrite, which
