Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.
Characteristics of Gold-Bearing Quartz Veins (Part 1) (Iron-stained or "rusty" quartz like this is a common gold-bearing vein material.) The single most common gold-bearing matrix in the world as a whole is the quartz vein .

Quartz is a crystalline structure that has a white to clear appearance. Bright white quartz with streaks of gray are a good indicator of the presence of silver ore. Bright white quartz with streaks of gray are a good indicator of the presence of silver ore.
Gold and silver are obtained from a variety of ores. Most people think of nuggets and such, but the truth is that very little comes from nuggets - nearly all newly mined gold comes from ores mined from the natural hard rocks that contain gold in tiny, even microscopic particles.
Visible gold in quartz is relatively uncommon: most productive gold mines are either dredge based for alluvial (moved by water) deposits, or cyanide float or mercury extraction of microscopic gold particles, either distributed in soil or hard rock (often quartz bearing) that are too small to see with the naked eye.
It features patches of "Cloud Gold" which is a speckling of small "dust"-like areas of Gold which are intergrown with white Quartz and associated with Galena, Sphalerite and Chalcopyrite, but the most INTERESTING aspect of this specimen is the fact that it features pink bands of the rare Manganese Silicate, Pyroxmangite! This association of Gold with Pyroxmangite is very rare, and possibly ...
Real gold in nature can come in many different forms, not just as gold nuggets. It can also be crystalline, mixed with quartz, fine flakes and dust. Gold look very different than most other minerals, but many people still confuse it.
Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging.

Finding Gold in Quartz One way that gold prospectors look for gold is too try and locate its source, the place where to gold forms in the earth. In epithermal gold deposits, it is quite common for sizable gold veins to run through quartz rock, and these specimens can be located using a quality metal detector .

Lode deposits of gold containing minerals are the result of volcanic activity, so minerals like quartz may appear near gold. Another type of gold ore is the result of cementing within hosts of sedimentary rocks after making its way down a river.
