Aug 21 2020 Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0 percent copper. The refining techniques employed by copper producers depend on the ore type as well as other economic and environmental factors.
Aug 21 2020 Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0 percent copper. The refining techniques employed by copper producers depend on the ore type as well as other economic and environmental factors. Currently about 80 percent of global copper production is extracted from sulfide sources.

Tenorite Cu 2 O is an ore of copper. Given that copper has a mass of 63.5 and oxygen a mass of 16 calculate the percentage by mass of copper in tenorite. Reveal answer.
The average copper content of ore deposits is usually below the average yield of the ore accessed in the early years of production. The initial grades of new mines have not declined over the past forty years and there has been no perceptible tendency for the average grade of porphyry deposits brought into production to decline over time.
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 12860 kg. Multiplying that number by 2.2 poundskg would give us the number of pounds about 28300 pounds.
The principal copper ore mineral is chalcopyrite CuFeS 2 which is commonly smelted to yield a matte containing 50 copper. In the presence of silica flux iron is selectively oxidized to a slag.
The principal ores of copper with the approximate percentage of copper found in each is as follows: Cuprite a copper oxide which contains 89 per cent of copper. This is the ore that is richest in copper frequently shading to crystals of native copper. Chalcocite a copper sulphide containing 80 per cent of copper.
The zinc content of mined ore is usually between 3 and 10 percent. Almost all ores contain the lead sulfide mineral galena and small quantities of cadmium sulfide. Chalcopyrite and copper-iron sulfide is often present. The most common gangue constituents
