The search process of precious metals

Hi back again with me at @ muklis, this time I will discuss about gold. Why I discuss about gold because in my country that is very much Indonesia contains gold so let me share a little how to get gold.

Geologically Indonesia is an area that there are many ancient mountains. In addition to fertilizing the land of ancient mountains in Indonesia a lot of gold metal deposits, silver, copper and other metal minerals.
In the search process of a place or area that has potential gold content, the process of location survey is very important and must be done. In order for us to know the area contains the potential of gold metal or not. All gold mines are either small or large mines to locate gold content in an area through a survey activity, be it rock type surveys or survey the characteristics of the formation of rocks.

A very simple way early stage for the survey to find the location of the gold content or can not by finding the gold content of eluvial or commonly known as free or free gold, which is a type of gold in the form of granules. This method can be used in the search location survey of new gold content.
The incidence of eluvial or gold placer deposits is formed by rainfall and the concentration of gold sediments from the occurrence of primary gold. For millions of years the extreme weather has transformed mountains and hills, resulting in the erosion and breaking of rocks on mountains or hills. Then the easily crumbled and broken rocks experience an erosion of natural processes, be it from rainfall, earthquakes, or other natural events that cause the material to move down to the bottom of the hill and into the waters of the river. From this event the mineral ore mineral material will be separated from the rock which then becomes a grain of gold grains.

Simple Ways And Techniques For Finding Areas That Have Gold Content Or Survey Location The presence of Gold.

In searching for eluvial gold we need to find the location of mountainous areas or hilly areas that have strong granite or crystal deposits as well as ancient mountains or hills. Usually the greatest potential to find gold for the region of Indonesia, the potential of gold metal deposits is located in 15 km or 20 km to the coast.

After finding the location to be surveyed, the first step we can find the flow of water or the river at the bottom or the base between the hills, trenches or hollow basins or rock material avalanches from the top of the hill can we survey, because the eluvial gold process occurs when the water flowing down from the top of a hill or mountain will carry eroded material and quickly towards the river, or basin.
After finding the water flow area, we try to survey rock and downstream direction or the bottom of river flow first. Do a repetition to see if there is a gold content or not. The process of repeating the most prospective gold in the flow of river bends, because at the bend of the river usually gold ore often stuck there. we can try to extract or dig sediment of soil or sand from the river and then do the replication with a tool or a pot, and other tools.
If downstream we do not find a gold point in the process of repeating, the process of repeating is done again in the uppermost part of the river from the first repeating location, and this step is done periodically and continuously, If finding rocks from the hill in the river, the identification process can be done by splitting some or panning from rock avalanches. The process of survey and identification to find locations containing gold like this is also done by the world's largest gold mining surveyor PT Freeport.

If the river flow has found a gold point, one or two points of the precious metal then the location of the discovery of gold seeds can be given a sign. Then the repetition is done back in the upper stream section of the first location where the gold point is found. Search up the top of the stream, to where the gold metal is not rediscovered.

If the flow of the river that has gold content is only located in the first location, or found also at the top of the river flow, it can be concluded that gold mineral content is in the hill location located in the area of ​​the discovery of the last gold point. Then in the hills or mountains can be in search of quartz avalanches or rocks that can be used to identify golden rock.
