It is in a metallic state, so mechanical processing can get quite a bit if it is in a nugget form.
By reduction-oxidation reaction you can extract metals, including Gold, from ore.
Gold is formed independently from rocks so unlike iron or copper there is no 'ore' to extract it from. In general gold is acquired by finding nuggets in rocks. The gold is simply chipped off from the rock. It is extremly difficult if not impossible to extract the small traces of gold that can be found in many rocks and as far as i am aware no commercial technique for acccquiring such gold.
you take the gold out of it
Yes coal is easy to extract. Especially surface mining. Underground mining is a little more difficult
You can !!! However, gold is a very inert element and is found 'native'; as nuggets. So there is no need to reduce goild with carbon.
It sold we cannot break it easy as we think
people use gold because its a un reactive metal {very easy to extract}
.
Because it is found deep down in gold mines; it is hard to find. It is also because it is shiny so it is used for jewelery quite often, and so it's expensive because people want to make a profit out of it.
It's a sort of vicious circle. Gold is expensive so it is much in demand. So gold is extracted from rocks where it forms an ounce or less in every ton of rock - which is expensive! Iron is not so rare and is easier to extract.

by chipping the rock of the gold
limestone is commonly used because it is easy to extract and carve
you dont.
sure
