Gold in Quartz Rock RareGoldNuggets Jul 20 Finding Gold in Quartz One way that gold prospectors look for gold is too try and locate its source the place where to gold forms in the earth In epithermal gold deposits it is quite common for sizable gold veins to run through quartz rock and these specimens can be located using a Gold is a chemical element with the symbol Au from Latin aurum and atomic number 79 making it one of the higher atomic number elements that occur naturally In its purest form it is a bright slightly reddish yellow dense soft malleable and ductile metal Chemically gold is a transition metal and a group 11 element It is one of the least reactive chemical elements and is solid

that contains a frothing agent which causes the water to foam a collecting agent which bonds onto the gold forming an oily film that sticks to air bubbles and a mixture of organic chemicals which keep the other contaminants from also bonding to the air bubbles Aqua regia dissolves gold though neither constituent acid will do so alone because in combination each acid performs a different task Nitric acid is a powerful oxidizer which will actually dissolve a virtually undetectable amount of gold forming gold ions Au 3

chemical extract gold from quartz Home Quartz and gold are commonly found together but this is where the two minerals similarities end Quartz is a plentiful mineral whereas gold is rare and prized Even though the minerals are found together physically Pyrite and Coal Mining Sulfur occurs in coal in three different forms 1 organic sulfur 2 sulfate minerals and 3 sulfide minerals mostly pyrite with minor amounts of marcasite When the coal is burned these forms of sulfur are converted into sulfur dioxide gas and contribute to air pollution and acid rain unless they are removed from the emissions

In these cases metal extraction is due to the production of organic acids and chelating and complexing compounds excreted into the environment At present bioleaching is used essentially for the recovery of copper uranium and gold and the main techniques employed are heap dump and in situ leachingGold is one of the important noble metals It is widely used by all people in India In pure form it is yellow in color Gold is mainly found in the native state either mixed with quartz in ancient rocks vein gold or scattered in sand and gravel placer gold or in the alluvial sand alluvial gold

To dissolve or partially dissolve the quartz from around gold silver etc you need to use fairly concentrated HF and then the process will be slow a day or two or more depending upon on how much you want to remove Massive quartz bull quartz chalcedony and opal are attacked much more quickly than the surface of regular quartz crystalsPreg robbing is an important phenomenon that inhibits gold recovery due to the presence of naturally occurring carbonaceous matter In case of certain ores gold recovery by cyanidation is limited by the presence of naturally occurring carbonaceous material that adsorbs gold from alkaline cyanide solution unless steps are taken to prevent this adsorption reaction from occurring
