Extraction of gold and other precious metals from their ores by treatment with mercury is called amalgamation. Gold dissolves in aqua regia, a mixture of hydrochloric and nitric acids, and in sodium or potassium cyanide. The latter solvent is the basis for the cyanide process that is used to recover gold from low grade ore.
Gold is often classified and labeled according to its size. Various sized pieces of gold are labeled as to their different mesh sizes. Coarse gold or nuggets are agreed to be any pieces of gold which will not pass through a 10 mesh screen. Medium sized pieces of gold, flakes and so forth, are of the 10 20 mesh range, of which it

as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation. Advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size 28 mesh which means that ore grinding costs are minimized.
It sounds absurd, but our resident alchemist, Mikey B got it to work. The gold that we got this way looked a bit black and bitty, but it was definitely gold. I don't know how efficient the process was, but we probably got a couple of grams of gold from several large sacks of our gold bearing rock.
A. Technological inventions can increase the efficiency of gold extraction from the ore. B. New sources of the gold ore are found through better exploration techniques. C.

Normally, the ore is crushed and agglomerated prior to heap leaching. High grade ores and ores resistant to cyanide leaching at coarse particle sizes, require further processing in order to recover the gold values. The processing techniques can include grinding, concentration, roasting, and pressure oxidation prior to cyanidation.
As you can see in the example above, the deposit does not have to be enormous in size only 500 meters long by 100 meters wide to contain a valuable deposit approximately $6 billion worth of minerals. However, in order to be as realistic as possible about this valuation, you can not assume thatplete ore body contains the same grade i.e. 2 copper and 1.5 gram per tonne gold.
