Gold Mining Methods
Today, gold is extracted in hardrock mines that directly mine the source rock, or "lode" of gold, where it was originally deposited by geochemical processes. Most ore accessed this way today contains only microscopic grains of gold, and it takes tons of rock to produce ounces of gold. Hardrock mines can be either underground mines or strip mines, and are usually more environmentally

Extraction of Gold
The process is applicable directly to gold- bearing sand, and to gold-bearing rocks after crushing. The crushing is effected by stone-crushers, rolling-mills, and stamp-mills. The washing is carried out either by subjecting the material to the prolonged action of flowing water, or by mechanical agitation with water in deep iron pans or " cradles." In California hydraulic jets are employed to

How Is Gold Formed? Origins and Process
In these events, gold formed during the r-process. Gold sank to the Earth''s core during the planet''s formation. It''s only accessible today because of asteroid bombardment. Theoretically, it''s possible to form gold by the nuclear processes of fusion, fission, and radioactive decay. It''s easiest for scientists to transmute gold by bombarding the

Extraction of Gold
Gold can be extracted by washing only when it is present as metal in the form of particles which are not too minute. The washing removes the specifically lighter parts of the material, the heavier gold particles sinking to the bottom. The process is applicable directly to gold- bearing sand, and to gold-bearing rocks after crushing.

The Mining Process – Waihi Gold
The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

How to Test Ore or Rock for Gold Content
If no gold or native silver can be seen in the rock, take a representative sample of about 300 grams and grind it up to pass a No. 30 sieve. Weigh out 250 grams and carefully pan down until most of the gangue is removed. Examine the heavy residuum for metallics. Should any be found it will be well to see how much can be amalgamated.

Finally, once the rock is fully crushed we get to the part about separating out the gold from the crushed rock. Often, this is accomplished simply by very careful panning. Panning is the most suitable method if you only have an amount of rock less than about 15 or 20 pounds. On the other hand if you are going to be processing large quantities of rock on a regular basis such as would come from

Gold Cyanidation
Process. Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock.
