Some copper ores can be converted into copper(II) sulphate solution by leaving the crushed ore in contact with dilute sulphuric acid for a long time. Copper can then be extracted from the copper(II) sulphate solution. But, in many cases, it is possible to separate the metal compound from unwanted rocky material by physical means.

copper is extracted and concentrated by froth flotation in which ground ore is mixed with reagents in an aerated tank filled with water. The hydrophobic copper sulfide particles attach to the air bubbles and float to the surface where they form a froth that is skimmed off (see Lesson Plan on Copper Extraction for more details on this process).

Extraction of metals. The process of extracting metal ores buried deep underground is called Mining. The metal ores are found in the earth's crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridges.

Ground water leaches ore minerals and redeposits them in zones near the water table. This leaching process concentrates these minerals as ore that can be mined. Of the 15 major types of mineral deposits in the Western Hemisphere formed by action of ground water, 13 occur in deserts. The copper ore mined here is in a bed that averages 150
