Mining of coal and metallic minerals in Washington began in the mid to late 1800s. Coal production in Washington hit a high in 2003 with an estimated total production of 6,232,000 short tons, yet production ceased in 2006. Metals mining during the same general time period occurred on both sides of the Cascade divide, but was largely concentrated in the northeastern portion of

 · Where Does Metal Ore Come From? Most metals that we use come from metal ores found in the earth's crust. Metal ores are made up of different compounds. Bauxite for example contains about 99 percent aluminum and magnetite about 72 percent iron. These metal ore deposits that contain large percentages of a single element are the easiest to extract.

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 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 ...

The structure of Galena is identical to that of halite, NaCl. The two minerals have the same crystal shapes, symmetry and cleavage. Some Galena may contain up to 1% silver in place of lead. The large volume of Galena that is processed for lead produces enough Silver as a by product to make Galena the leading ore of Silver.
