Mineralization. However, much copper pyrites in a gold ore causes difficulties in extraction with cyanide. Other minerals found in gold deposits are galena, zinc blende, mispickel, stibnite, bismuthinite, and the sulphurarsenic and sulphurantimony compounds of lead and copper; also molybdenite, and pyrrhotite.
Much of the gold mined is actually from gold ore rather then actual Gold specimens. The ore is often brown, ironstained rock or massive white Quartz, and usually contains only minute traces of gold. To extract the gold, the ore is crushed, then the gold is separated from the ore by various methods.
gold miners Smallscale miners Some SSM communities continue to practice the same method of gold extraction developed by their forefathers, whereas other groups are innovative and try to improve working techniques to increase gold recovery rates. An excellent example of this is a group of SSM in the Benguet province in the Philippines.
Specimen gold is generally found and retrieved from lode gold deposits. These are usually highgrade occurences found in quartz veins, or less commonly calcite. Gold may also be found as specimens in, or with iron oxides, adularia (a lowtemperature feldspar), sulfides, and with other silicarich minerals such as tourmaline, amythest, or clay minerals.
Gold Quartz Discovery Site. This is where George McKnight discovered gold in Grass Valley in October, 1850 and where California quartz gold mining began. Jenkins Street and Hocking Avenue. Hardrock Gold Mining. An estimated 500 million in gold has been mined within a onemile radius of this historic marker. Near the creek in Memorial Park.

Gold is one of the first minerals used by prehistoric cultures. The Latin name for this mineral was "aurum" and Jöns Jakob Berzelius used Au to represent the element when he established the current system of chemical symbols.
In the case of quartztype gold deposits, gold ore can be associated with pyrites both within the quartz vein and on the periphery (the alteration halo effect), as well as purely with the quartz material itself,– though generally in lesser concentrations.
1 In lode or vein deposits, the gold is mixed with another mineral, often quartz, in a vein that has filled a split in the surrounding rocks. Gold is obtained from lode deposits by drilling, blasting, or shoveling the surrounding rock. Lode deposits often run deep underground.
of northern Yuma County .and much of the country around Quartz site and farther west to the reservation line.
