May 27, 2016Coal ash from the Appalachian Mountains saw the lowest extraction percentages, while ash from the Powder River Basin saw the highest. Hsu-Kim thnks this might be because the rare earth elements in the Appalachian Mountain coal ash are encapsulated within a glassy matrix of aluminum silicates, which nitric acid doesn't dissolve very well.diergetos179.jpg" />

Water that has dissolved silica, from silicon-based rocks (like 90% of earth's crust) crystallizes into quartzes, which include Amethyst; Rose quartz; Tiger's eye; Chalcedony and carnelian; Agate and onyx; Opal is also formed from silicon-carrying water inside cracks or voids.diergetos271.jpg" />

Silica is the name given to a group of minerals composed of silicon and oxygen, the two most abundant elements in the earth's crust. Silica is found commonly in the crystalline state and rarely in an amorphous state. It is composed of one atom of silicon and two atoms of diergetos339.jpg" />

But the amount of gold in the earth is extremely small, so that mining is not really worthwhile. Generally there are two types of gold primary gold ("mountain gold" from mines) and secondary gold ("stream gold", "nuggets"). Above all the extraction of primary gold is associated with considerable effort.diergetos16.jpg" />

Underground copper mining in Butte, Montana since the 1870's has resulted in over 49 miles of vertical shafts and 5,600 miles of horizontal workways. In 1955, high copper prices drove Anaconda Copper Mining Company to open a new pit mines including the Berkeley Pit.
