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.
Gold is relatively non-reactive, a characteristic property of gold.Gold is found in natural state. It is gold and does not need to be refined or processed. All that may be needed is to extract it from a containing rock or just picked up off the ground. Gold does not tarnish or deteriorate
No one person. Gold is rare and useful- the rarity makes it expensive. If there was gold sitting around everywhere, it would not be expensive.
gold is more expensive than iron simply because iron is more common and gold is also a purer metal
totalySilver is very expensive compared to other elements such as iron or steel, and is the most expensive after gold.
it was expensive
It sold we cannot break it easy as we think
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.
people use gold because its a un reactive metal {very easy to extract}
Gold is a natural element. It is normally found as a solid metal and is relatively rare and expensive.
Platinum is more expensive than gold because of the difficulty associated with mining it. Platinum is harder to mine than gold, which means it requires more energy and effort to extract.

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.
you take the gold out of it
by chipping the rock of the gold
yes you can, but it is very expensive to do for just one camera, and you will get at most 2-5 grams of gold. however if you do it on a big scale (think thousands of cameras a day) then its a bit more profitable.
you dont.
