Normally even good, rich gold ore has no gold metal which is visible to the naked eye. The photo at left shows small particles of metallic gold in quartz taken from the mountains of Canada. Sections of gray colored quartz in the specimen have this appearance because of the finely disbursed sulfide crystals present in this ore.
The gold ore is then gathered up and taken to a mill for refinement. 2 Placer deposits contain large pieces of gold ore (nuggets) and grains of gold that have been washed downstream from a lode deposit and that are usually mixed with sand or gravel.

Uses of Gold in Awards & Status Symbols. What metal is used to make the crown worn by a king? Gold! This metal is selected for use because gold is THE metal of highest esteem. It would make no sense to make a king's crown out of steel - even though steel is the strongest metal.
Although there are about twenty different gold minerals, all of them are quite rare. Therefore, most gold found in nature is in the form of the native metal. Gold occurs in hydrothermal veins deposited by ascending solutions, as disseminated particles through some sulfide deposits, and in placer deposits.
When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.
Apr 25, 2017· Gold can be leached from stone through alkaline or acidic-based products, including halogens, such as chlorine, iodine and bromine. Halogens are reactive, non-metal elements with seven electrons in their outer shell which allow them to easily combine with other elements. The use of chlorine is both the cheapest and ...
Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold .
