The principal minerals that serve as major sources for iron, copper, zinc, and lead are as follows:

Iron: The most important sources are hematite, magnetite, limonite, and siderite.12
Copper: The principal sources are chalcopyrite, bornite, and chalcocite.1
Zinc: The chief source is the sulfide mineral sphalerite, along with its oxidation products smithsonite and hemimorphite.13
Lead: The primary source is galena, a lead sulfide.41

These minerals are often found within mineral deposits mixed with valueless rock known as gangue. Because mining and processing these materials can have significant environmental impacts, it is essential that the industry adheres to strict environmental protection standards to manage residues and effluents responsibly.15
