In What Rock Formations Can Gold Be Found? | Sciencing
· Intrusive rock is typically very hard and erodes slowly. This allows the surrounding rock to be worn away by wind and water, leaving only the harder rock in place. Heavy particles, such as gold, are likely to accumulate against the harder rock while the lighter materials are more easily moved away.
GEOLOGY OF SEDIMENTARY ROCKHOSTED GOLD DEPOSITS
sedimentary rockhosted gold deposits in China. These breccia bodies are conformable with stratigraphic units in the host rock. An example of this is the Shuangwang gold deposit (Fan, and Jin,, 1994), which is a large Carlintype gold deposit in the Qinling area, hosted by stratabound breccia bodies (fig. 29),
Tons of Rock for an Ounce of Gold
· But the bottom line is that it takes tremendous amount of rock to yield just specks of gold. In Q1, it took Barrick anywhere from 2 tons to 91 tons of rock to produce just 1 ounce of gold.
What is Placer Gold and How do You Find it ...
· Placer gold deposits are usually not far off from where lode gold deposits are. The gold in hard rock is released during the weathering process and then it carried off by glaciers or running water (streams, rivers, flood water) to someplace where it is deposited and concentrated in a placer deposit.

Gold CIL CIP Gold Leaching Process Explained CCD
· The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carboninleach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks.
A Guide to the Four Main Methods of Mining
· Famously, "panning for gold" can be part of the placer mining process. In placer operations, the extracted sedimentary material is rinsed and sluiced to pull out the desired minerals. In addition to gold, gemstones, platinum, tin and other materials can be extracted via place mining.
Extraction of Gold
The process is applicable directly to gold bearing sand, and to goldbearing rocks after crushing. The crushing is effected by stonecrushers, rollingmills, and stampmills. 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 ...

Gold in Quartz
Free gold taken from hard rock ores always contains at least a little silver, with the average gold fineness typically being in the range of around 80 percent, but it does vary quite a bit. Any associated sulfides in the ore are likely to carry more silver in proportion than the native gold. Some types of quartz veins can carry a significant amount of silver, with the greatest amounts found in ...
