بيت /extraction of copper different stages
Malachite is a copper ore consisting mainly of basic copper(II) carbonate, (OH)2. In this experiment, students learn how to produce copper from copper(II) carbonate by heating it to produce copper(II) oxide, which is then reduced to the metal using carbon as a reducing agent.

· The important ores of copper are copper pyrites ((CuFeS_2)), cuprite and copper glance. The copper ores are mostly found in the north of India. The extraction of copper also involves many steps. The ore used for extraction is copper pyrites, which is crushed, concentrated and then heated in the presence of air.

Steps of Extraction of Metals. Concentration of ores: Removal of impurities, such as soil, sand, stone, silies, etc. from mined ore is known as Concentration of Ores. Ores which are mined often contain many impurities. These impurities are called gangue. First of all, concentration is done to remove impurities from ores.
