How much is a gram of gold mine?

Generally speaking, the gold content of ore is 90 ~ 120 yuan/ton. A gram of gold mine is not worth much.

The price of gold is also changing with the change of international market, time and brand. If the international market changes, the price of gold will also fluctuate. In addition, time also

Will affect the price of gold. For example, there will be preferential activities on major festivals. At this time, the price of gold will be lower and will reach the original price on weekdays.

Of course, different brands will take root.

According to the workmanship and grade of this brand, the price of gold will be slightly different, which shows that the price is changing every day.

Introduction:

The types of gold deposits are complex and diverse. There are mainly conglomerate type, greenstone belt type, chronological pulse type, ductile shear belt type, Carlin type, porphyry type, epithermal type, volcanic type and Cenozoic placer.

The crust formed in the early development of the earth is rich in gold. Therefore, it can generally represent the Archean greenstone belt composed of early residual crust. Especially the combination of mafic and ultramafic volcanic rocks, the gold abundance value is higher than all kinds of rocks in the crust, which may become the earliest "source bed" of gold deposits.

Gold in the earth is 2.6× 10-6 in the core, 0.005× 10-6 in the mantle and 0.004× 10-6 in the crust. The abundance of gold in the crust is only1107 for iron and 1/2 1 for silver. More than 99% of the gold on the earth enters the core.

To sum up, the abundance value of gold in the crust is very low, and it has the properties of sulfur-loving, sulfur-loving, iron-loving and high melting point. To form an industrial deposit, gold must be enriched several thousand times to form a rich mine, and gold must be enriched several thousand times, tens of thousands of times or even higher. It is generally believed that large-scale gold deposits generally go through a long geological period, and can only be formed through superposition of multiple sources, geological structure evolution and multiple mineralization.
