Various investigators studied the extraction of PMs, copper, lead and zinc from e-waste using hydrometallurgical routes [11,37,38,39,40,41]. These routes are based on traditional hydrometallurgical technology of metals extractions from their primary ores. Similar steps of acid or caustic leaching are employed for selective dissolution of PMs ...

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.

Copper oxide minerals are the products of weathering and hydrolysis of primary copper sulfide (e.g., chalcopyrite), mainly including malachite, azurite, chrysocolla, arnimite, tenorite, and cuprite. Copper sulfide is the main raw mineral material for copper, and its copper output accounts for over 80% of total output.

The position of the metal on the reactivity series influences the method of extraction. Those metals placed higher up on the series (above carbon) have to be extracted using electrolysis. Metals lower down on the series can be extracted by heating with carbon. The Extraction Method Depends on the Position of a Metal in the Reactivity Series.
