Gold has captivated humanity for millennia, but did you know that most of Earth’s gold is incredibly scarce? Let’s explore how this precious metal concentrates in riverbeds and the modern methods used to recover it.<\/p>\n

How Much Gold is There in The World?<\/h2>\n

First, we need to know that the most common chemical element in the earth’s crust is oxygen, which accounts for 48.6% of the total weight; followed by silicon, which accounts for 26.3%; the following are aluminum, iron, calcium, sodium, potassium, and magnesium.<\/p>\n

The above eight elements accounted for 98.04% of the total weight of the Earth’s crust, and the remaining 80 elements accounted for 1.96%. The average content of Au (gold) elements in the earth’s crust is <0.01ppm (that is, <0.00001\u2030), and the content is very, very small.<\/p>\n

Through a series of mineralization activities such as magmatism and crustal movement, gold is enriched to 1 gram per ton, that is, one gram of gold per ton of ore, i.e., 0.001\u2030.<\/p>\n

\"\"<\/p>\n

 <\/h2>\n

How Is Placer Gold Formed?<\/h2>\n

Because of the movement of the earth’s crust, the gold in the depths of the earth has been “squeezed out” (also from the volcano), which is why it is generally found in gold mining areas in the middle of the two plates or in the deep valleys of the mountains.<\/p>\n

After coming out of the crust, a small amount of gold is enriched in the rock, but after the weathering and erosion, as well as the structure and other broken rocks, the gold-rich ore is shattered (takes a very long time).<\/p>\n

Under the action of flowing water, gold ore fragments are brought into the river and further shredded during the handling process, slowly separating the gold from the ore.<\/p>\n

Since gold is a large specific gravity mineral with a specific gravity of 19.32 g\/cm3, fine gold will deposit at the corner of the river (slow flow rate), forming the placer gold deposit where you are looking for.<\/p>\n

 <\/p>\n

 <\/p>\n

The actual formation of geological structures varies widely. River gold is generally in the sand layer and not in the rocks. In order to get the gold sand, it is often necessary to drill about 20 meters deep (forget the human labor).<\/p>\n

What you see in the above picture, gold mining by hand, is either the scene of the original operation in Africa or the final screening operation after the mechanical process is done.<\/p>\n
