Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.

A quarry is a place where rocks, sand, or minerals are extracted from the surface of the Earth. A quarry is a type of mine called an open-pit mine, because it is open to the Earths surface.Another type of mine, a sub-surface mine, consists of underground tunnels or shafts.. The most common purpose of quarries is to extract stone for building materials.
Large open-pit copper mines can produce up to a million tons of waste and ore per day and can be mined at that rate for decades. Quarrying is similar to open-pit mining except the term is commonly applied to the extraction of dimension stone and aggregates.
This is to avoid rupture, which can be dangerous and expensive. Examples of Copper Structures. Copper is not easy to quarry, not to mention in low abundance.
