Ore deposits are crustal concentrations of useful elements that can be exploited at a profit. Like all crustal rocks, they consist of minerals formed by geological processes. There are four basic geological requirements for any ore deposit to form (Figure 1): i) a source for the ore components (metals and ligands); ii) a mechanism that either transports these components to the ore deposit ...

Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element ...
Lead is a naturally occurring, bluishgray metal that is found in small quantities in the earth's crust, predominatly in lead ore, the most important of which is galena. (1,2) Lead is present in a variety of compounds such as lead acetate, lead chloride, lead chromate, lead nitrate, and lead oxide. (1,2) Pure lead is insoluble in water; however, the lead compounds vary in solubility from ...
