Gold Its Occurrence in Illinois. Gold is not known to occur in minable deposits anywhere in Illinois, so prospecting essentially refers to recreational panning. Gold has never been mined in Illinois, not even as a by-product of other types of mining such as fluorite, zinc-lead, or sand and gravel. Information about panning for gold is available at sites such as Mining Links.
Occurrence of Gold. Gold is one of the worlds most precious metals. It is called a noble metal because it does not react with air under ordinary conditions. Gold is deposited from solutions containing dissolved gold. There are two main types of gold deposits. When gold is found at the place where it was formed, the deposit is called a primary deposit, or lode deposit.
The Burnt River and its tributaries have yielded gold. Farther to the west, placer mining (particularly dredging) has been carried on for many years in the John Day River valley. In southwestern Oregon, tributaries of the Rogue River and neighboring streams in

Early Gold Finds and Production. Gold was produced in the southern Appalachian region as early as 1792 and perhaps as early as 1775 in southern California. The discovery of gold at Sutters Mill in California sparked the gold rush of 1849-50, and hundreds of mining camps sprang to life as new deposits were discovered.
Gold usually occurs in its metallic state, commonly associated with sulphide minerals such as pyrite, but it does not form a separate sulphide mineral itself. The only economically important occurrence of gold in chemical combination is with tellurium as telluride minerals.

Apr 16, 2019 Historically, mercury has been widely used in placer gold mining to form mercury-gold amalgam with smaller gold particles, thereby increasing the rate of gold recovery. In the 1960s, large-scale mercury use stopped. In artisanal and small-scale gold mining (ASGM), however, mercury is still used, often clandestine, gold prospecting.

Arsenic is a common element in the natural environment and is frequently a significant component in gold deposits of the western United States. Such deposits contain various forms of arsenic arsenides, sulfides, and sulfosalts. Upon weathering such minerals routinely lower the pH of nearby waters, mobilizing arsenic and other metals. Arsenic may also be mobilized in aqueous environments where ...
