Rock Contact Zones and Faults: Many quartz veins and other hard rock gold deposits occur in quot;zonesquot; along faults or at the contact of two different types of rock. Correct Topography: As a general concept, the coarser gold does tend to hang up farther upstream.
The gold can be such small particles as to be invisible to the naked eye, or as larger aggregates of easy to see blobs, leaves and crystals in cavities in the quartz. The gold fills cracks and spaces in the quartz as the ascending goldbearing solutions infiltrate the existing quartz vein, filling in
While the presence of quartz alone is not a very good indicator of where gold can be found, there is no doubt that there are many gold districts where gold and quartz have a strong correlation. I generally consider quartz to be a good indicator once I know that I am in a known gold bearing area, and I have identified that there is a relationship between gold and quartz in that particular area.
Quartz is one of the most common minerals in the Earths crust. As a mineral name, quartz refers to a specific chemical compound (silicon dioxide, or silica, SiO 2), having a specific crystalline form (hexagonal).It is found is all forms of rock: igneous, metamorphic and sedimentary.

These veins are where hard rock gold mines follow and remove the gold bearing quartz. Usually, the ground where gold lodes are now used to be near volcanoes that perished many millions of years ago. To get an idea of the time span involved, some major goldbearing quartz finds which are considered younger are about 400 million years old.
Of all the methods of extracting gold amp; processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery

Gold prospecting and identifying goldbearing areas have become increasingly more feasible, due to research developments on the geological process of gold formation. (See References 1.) Gold bearing areas, mostly throughout the western United States, have drawn and sprouted entire communities based on prospecting.
Quartz is one of the most common minerals in the Earths crust. As a mineral name, quartz refers to a specific chemical compound (silicon dioxide, or silica, SiO 2), having a specific crystalline form (hexagonal).It is found is all forms of rock: igneous, metamorphic and sedimentary.
When gold dissolution is complete, the goldbearing 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.
Separating fine gold particles from black sands is one of the biggest challenges that gold prospectors have to deal with. This article will describe a simple and inexpensive method of capturing fine gold. Most small scale prospectors do not need to invest thousands of dollars to capture small placer gold dust. Using fine gold recovery methods, you can retain the vast majority of gold in your
Gold is easy to spot in white quartz. Use your geology hammer and sledge to break open quartz and potential goldbearing rocks. Place an iron or steel anvil in a large flat pan to prevent loss of rock powder and contained gold. Look for large pieces of gold that you can collect manually or with tweezers.
