In the old days it was extracted from mines with pick axes. Gold nuggets were dug from veins of crystal quartz that often included silver, Mercury, and lead.
Today most of that ore has been tapped, and new methods are employed. The gold is no longer even visible to the naked eye--it is dust, scattered throughout an ore body in a zone. Strip mined ore is piled on slanted V shaped sheets of plastic where it is sprayed with a solution of cyanide. The cyanide bonds with the gold which settles into a pond. The pond is drained, the rich ore scooped up and further processed to recover the gold.
A profitable ore body may contain as little as 0.02 oz of gold per ton of ore. I have toured several gold mining operations in northern Nevada, and have staked claims for other mines there.

How is gold extracted form the ore?
Gold is typically extracted from gold ore through a process known as cyanidation, where cyanide solution is applied to the crushed ore. The cyanide solution helps dissolve the gold, which is then separated from the ore using processes such as carbon adsorption or zinc precipitation. Finally, the extracted gold is further refined to achieve high purity levels.
What is the metallurgy of gold?
Gold is typically mined as ore containing gold particles, which are then extracted through various methods such as cyanidation or smelting. Once extracted, gold can be refined through processes like cupellation, where impurities are removed through oxidation. In terms of purity, gold is often measured in karats, with 24 karat gold being the purest form.
How was gold exracted from gold ore?
Gold is typically extracted from gold ore using a combination of chemical processes. The most common method involves cyanidation, where cyanide solution is used to dissolve the gold from the ore. The dissolved gold is then extracted from the solution through adsorption onto activated carbon, followed by refining to obtain pure gold.
An Olympic medal contains 71.5 percent of gold by mass How much gold could be extracted from a medal that weighs 115 grams Answer in units of mol?
To calculate the amount of gold in moles, we need to first determine the mass of gold in the medal. From the information provided, 71.5% of the medal's mass is gold. Therefore, the mass of gold in the medal is 0.715 * 115 grams. Next, we convert this mass into moles using the molar mass of gold, which is approximately 197 grams/mol. The amount of gold that could be extracted from the medal in mol is (0.715 * 115) /197.
How did gold extracted from gold ore?
Gold is extracted from gold ore through a process called cyanidation, which involves the use of cyanide solution to dissolve the gold from the ore. The dissolved gold is then separated and purified through various refining processes to yield pure gold.
What metal is extracted from gold?
Metal cannot be extracted from Gold, as Gold itself is a metal.
Where is gold extracted?
Gold is extracted from the earth itself, near the place underground where coal miners work.
Is gold being or has gold been extracted from seawater?
Gold has been extracted from seawater, but the cost is not worth the effort for the very small amount that can be obtained.
What is a rock which gold is extracted?
Gold is commonly extracted from a type of rock called quartz. Gold is often found in quartz veins that run through the rock, and the gold can be separated by crushing the quartz and then using chemicals to extract the gold.
What minerals are obtained from gold and copper?
Gold and Copper are chemical elements. No "minerals" can be extracted from them other than 'gold' and 'copper'. They can be extracted from the minerals or 'ores' named in the other answers herein.
How is gold extracted form nature?
Something else.
How is gold extracted form the ore?
Gold is typically extracted from gold ore through a process known as cyanidation, where cyanide solution is applied to the crushed ore. The cyanide solution helps dissolve the gold, which is then separated from the ore using processes such as carbon adsorption or zinc precipitation. Finally, the extracted gold is further refined to achieve high purity levels.
How much gold is extracted from the amazon each year?
It's challenging to quantify the exact amount of gold extracted from the Amazon each year due to illegal mining activities. Estimates suggest that tens of tons of gold are extracted annually from the Amazon region, leading to significant environmental and social impacts.
How is gold extracted from gold ore?
Gold is typically extracted from gold ore through a process called cyanidation, which involves leaching the gold out of the ore using cyanide solution. The gold then forms a soluble cyanide-gold complex that is extracted from the solution through various methods, such as carbon adsorption or precipitation. Finally, the gold is further purified and refined to remove impurities and obtain pure gold.
Can Gold be extracted from sea water?
yes yes yes
What did the miners do when the gold is once extracted from the ground?
the pounded by there and not boiled
What did they do with gold once they extracted from the ground?
Gold that is extracted from the earth is in its ore form, meaning that the gold is mixed with other minerals in the rock. The gold ore is processed by breaking it up into small pieces and heating it to remove the gold, which is extremely soft and melts at a very low temperature, leaving the rock behind.
