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.

Open cast mining is commonly used to extract minerals such as coal, copper, iron, gold, and bauxite. It is a surface mining technique where the rock or minerals are extracted from the earth through an open pit.
Gold is considered a natural resource because it is a naturally occurring metallic element that is typically found in the Earth's crust. It is mined and extracted from the ground through various mining processes. Gold is valued for its beauty, scarcity, and various industrial uses, making it an important natural resource.
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.
Gold is typically harvested through mining, where gold ore is extracted from the earth using various techniques such as open-pit mining or underground mining. Once the ore is extracted, it is processed to separate the gold from other minerals, usually through a combination of crushing, grinding, and chemical processes. Finally, the extracted gold is refined into pure gold bars or other forms for commercial use.

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.

Metal cannot be extracted from Gold, as Gold itself is a metal.
The Gold Rush ended on 1855 by which time alluvial gold areas were depleted and gold had to be extracted from rock, which required mechanical equipment not available to diggers.

Gold is one of the few metals that is found as pure metal in the ground. It can be extracted from the rock containing it by mechanical or chemical processes.
Gold is extracted from the earth itself, near the place underground where coal miners work.
Gold has been extracted from seawater, but the cost is not worth the effort for the very small amount that can be obtained.
Gold does not occur as ores!It is naturally pure metal when extracted and doesnot need to be separated as it does ot have any chemicals.Yes,if rocks or debris is attached,then it may be crushed and the worthless rock may be removed.
