Galena has a defined vision to develop Abra as a high-grade, high margin mining operation. Metals are found in the Earth either as compounds or, in the case of very unreactive metals, as the crust of the uncombined element. The rock that contains the metal is called an ore. Common metal ores include bauxite (aluminium oxide), haematite (iron oxide), zinc blende (zinc sulphide), galena (lead sulphide), and cinnabar (mercury sulphide).Although lead makes up only about 0.0013% of the earth's crust, it is not considered to be a rare element since it is easily mined and refined. Most lead is obtained by roasting galena in hot air, although nearly one third of the lead used in the United States is obtained through recycling efforts.
