What's the golden stone from mining

1. Judging from the characteristics of the stone you mentioned, it should be pyrite, and the possibility of natural sulfur is not ruled out. Pyrite is the most common associated mineral in coal mine. Its main components are sulfur and iron, which are usually stuck together with coal. Coal with high sulfur content will proce sulfur dioxide gas in the process of combustion. This gas is pungent and bad smelling, which is harmful to human respiratory system. A large amount of sulfur dioxide gas will destroy the ozone layer and form acid rain when it is diffused in the air or evacuated. At present, according to the sulfur content of coal in China, the sulfur content of coal is divided into three levels: high sulfur coal with sulfur content greater than or equal to 3%, medium sulfur coal with sulfur content between 3% and 1%, and low sulfur coal with sulfur content less than 1%. In order to protect the environment, the state environmental protection administration stipulates that coal with sulfur content higher than 3% shall not be mined in principle; Large scale coal-fired units must be equipped with desulfurization devices or take necessary desulfurization measures. At present, there are two common desulfurization methods in China, one is desulfurization before combustion, the other is desulfurization after combustion. Desulfurization before combustion generally adopts magnetic method, that is, coal is ground into powder, and then pyrite containing sulfur and iron is removed from coal by magnet or electromagnetic device. Desulfurization after combustion mainly adopts the method of spreading quicklime in the exhaust system of combustion device. Quicklime reacts with sulfur dioxide in flue gas to form gypsum, so as to rece the emptying amount of sulfur dioxide
the situation you introced should be reported to the relevant authorities in time, so that the relevant departments can test the coal in your mine. If the existing resources or the mining is mainly high sulfur coal, then we should listen to the opinions of the relevant parties, stop mining or adjust the matching mining; If it is natural sulfur, it should also be determined by relevant parties to see if the reserves of natural sulfur have instrial exploitation value. This is not only responsible for the society, but also for your mine and yourself.

2. The photos are too blurred. The preliminary observation is like small pieces of placer gold or pyrite.

3. It's just a thing. Even if the gold mine can't be g ring construction, it's controlled by the gold army. You can't build here. Maybe it's a relic left behind

4. It's crystal 9717

5. What's the weight? Is it your local stone? How much do you want?

6. Ferrosulfide?

7. I can't see your picture clearly, but are you sure it's a stone? It looks like "gold foil" in a hazy way.

8.

It's pyrite, also known as fool's gold, and copper ore

Pyrite (FeS2) is often mistaken for gold because of its light brass color and bright metallic luster, so it is also called & quot; Fool's gold;. It usually contains cobalt, nickel and selenium, and has NaCl crystal structure

chalrite: chalrite, with mottled blue, purple and brown yellow film on the surface, streaked green black and metallic luster
streak method: mark the porcelain pieces with minerals to see the color of the powder left on the white porcelain plate.

10. It's a gold ore, copper green, iron red, and gold yellow
