193. The Gold Mine Is Worth Tens Of Millions, And The Hole Is Washed And Doubled, And The Highly Tox
The others didn't know why, but when they heard Fang Yang's yelling, they all ran back without even thinking about it.
This time it retreated a full hundred meters before stopping.
Fang Yang stopped and breathed heavily, touched his chest at the same time and turned to look at the photographer: "How is it, has my face changed color?"
The photographer looked confused: "Brother? What's wrong with you, it looks like nothing happened!"
Wang Dui also hurriedly asked with concern: "What's wrong with Fang Yang, are you okay?"
Fang Yang quickly took out his mobile phone to take pictures of himself, looked left and right, without saying a word, making everyone around him confused.
It wasn't until he was sure that there was nothing wrong with him that he breathed a sigh of relief: "I'll go! It's so dangerous, I almost confessed here today!"
The photographer hurriedly asked: "Brother, what did you see, do you want to call an ambulance for you?"
Fang Yang waved his hand: "I'm fine, don't worry. By the way, Brother Wang, I suspect that the five people before should have entered the mine.
Wang Dui was taken aback when he heard the words: "How do you know?"
"Because of the place that collapsed just now, there were several corpses underneath, some of which were covered by stones and mud, and I didn't have time to look at the specific numbers carefully, but it looks a bit similar in terms of body shape, all of them are wearing protective clothing, gas masks and oxygen tanks!"
"And I probably know why they appear here."
Everyone was shocked when they heard the words.
"With a gas mask and an oxygen tank?"
Cheng Liang hurriedly asked: "If it's really them, then what they packed when they went up the mountain were all oxygen cylinders?"
Wang Dui frowned: "You said you were wearing a gas mask. You can't confirm it just by your body shape. I have to go and check it."
After speaking, he was ready to walk towards the entrance of the cave.
Fang Yang hurriedly grabbed him: "Don't! Don't go there, don't you ever wonder why they died!"
Wang Dui's hairs trembled suddenly, a palpitation appeared in his heart, and he couldn't help but backed away.
The photographer asked curiously: "Brother, how are you sure they are dead? If they are not dead, maybe they need first aid!"
Fang Yang shook his head: "Impossible! I'm 100% sure I'm dead!"
As soon as this remark came out, everyone was curious and wanted to get an answer from him.
"Do you know why I was so scared just now?"
Everyone shook their heads: "I don't know!"
"Because at the moment I approached, I smelled a highly toxic gas called hydrogen peroxide gas.
Now everyone is even more confused, they have never heard of this thing.
At this time, it happens to be in the afternoon, which is also the hottest time of the day.
Everyone was sweating profusely after the intense running just now.
Fang Yang looked at the entrance of the cave with lingering fear and continued to explain: "It is generally impossible for this kind of chemical substance to appear here for no reason. According to the situation at the scene, I probably guess what they are doing up the mountain." [! "
Cheng Liang was impatient, and was the first to urge: "What are you doing?"
"Mining for gold!"
"gold!"
All the factory workers and factory managers, as well as Cheng Liang, looked incredible.
The factory manager, in particular, shook his head quickly: "Impossible, the experts in this place have been here many times, and the gold mine has long been turned into a waste mine, and there is no mining value at all. It can't be that the experts can't mine it, can they mine it?"
Fang Yang smiled, and said slowly: "Have you ever thought about why it cannot be mined? I don't doubt what you said. It is true that if miners are allowed to mine, the cost will be higher than gold, and the gain is not worth the loss. "
"In the middle, I still want to talk about a method of mining gold mines. There is a saying that gold mines are worth tens of millions. I don't know if you have heard of it."
Everyone, including the factory manager, shook their heads.
"Washing holes is a means of mining gold mines. This mining method is different from common mining methods, because the newly discovered gold mines have relatively large gold particles and are relatively easy to mine, so basically large-scale gold mines are used. Both mechanical and manual methods of excavation."
"However, the cost of this mining method is very high. Once the gold mine becomes a waste mine, there is no value for mining!"
"However, it is a lucrative industry for some illegal mining organizations, and their goal is to mine valuable gold mines in these urban areas!"
"In these gold mines, because the remaining gold particles are very fine, they are mixed with soil and stones, not only is it difficult to mine normally, but also the cost is higher, but the washing hole is different, and its cost can be said to be extremely high." Low, but very dangerous!"
Everyone listened attentively, just like elementary school students in class.
For this unknown knowledge, their curiosity is pulled to the peak.
The photographer hurriedly asked: "It's the first time I heard about washing caves. What do I use to wash? Water? But where does the water come from down here!"
Fang Yang shook his head with a smile: "You thought it was washing sand in the river, and washing it with water! This is a rock cave.
"The essence of cave washing is to melt the gold in the mudstone into a liquid by injecting a large amount of water and chemical substances. Then the liquid of gold is turned into Guen gold by chemical means."
"To put it bluntly, it is to turn all the rocks, gold, and soil into liquid through rough methods, and then separate them, so that the gold will come out."
"Not only is the cost much lower, but the total amount of gold harvested is also quite a lot. If you can sum up the hole washing in one sentence, it is a simple method with low cost and easy operation with high returns.
"Generally speaking, in a piece of slag, at most 1-2 grams of gold can be found, and this is not pure gold. After later purification, the gold content will be lower."
"However, for those who wash the cave, it is basically equivalent to buying and selling without money. Moreover, if you are lucky, you will find a lot of slag once you wash the cave.
You will also get a lot of gold. "
Wang Dui took a deep breath, this is the first time he encountered such a case: "How do they wash in the cave?"
Fang Yang replied lightly: "The nature of gold is very stable. Generally, it will not react with other chemical substances and be melted. Only a chemical called sodium cyanide can be used to turn gold into ions and dissolve it in the liquid."
"Finally, he was reduced to solid gold with activated carbon."
"The specific operation method is to hide at the bottom of a passage in the mine, set up pipelines in the mine, and flush the entire cave.
"In this process, a gold extraction agent must be used, and only water has little effect. Sodium cyanide and gold beneficiation agents must be added when washing the cave.
"At the same time, set a low-lying place, put enough activated carbon in the low-lying place, and remove the activated carbon after a period of time. There will be adsorbed gold there, and the gold will appear through high-temperature burning."
【Qi】+1+1+1+1.
[Fuck? It’s that simple? According to what I’ve said, I feel like I can do it! Brothers, today’s live broadcast was not in vain. I seem to have found a word to make a fortune. Is there a partner to do it together? I There just happened to be an abandoned gold mine here in my hometown. 】
——[I think you are really punished upstairs! Is it illegal to wash the cave? You still have a team to do it? Didn’t you hear Fang Yang just said that this thing is poisonous? I guess you are not going to make a fortune by then, They went together to destroy the group. 】
——【Long experience! It’s the first time I heard that gold can be washed out. I have to say that these people’s brains are really easy to use, but those who use these cleverness in the right way are not too bad. Life is inherently It's very short, and I have to take a shortcut. 】
[Thanks to Fang Yang for letting me find some inspiration for writing novels, I decided to write this web article, the name is called, a little trick to get rich every day, anchor, you are really punished! But if you have a conscience, twist some fruits and come to the hospital to see me !】
Everyone was amazed after listening to it, and even had the urge to try it.
After all, this is gold, who is not jealous.
But in the next second Fang Yang poured a basin of cold water over them.
".||Although cave washing is very profitable, there is a very big hidden danger, that is, safety issues. Mines that have been washed often become deadly man-eating caves."
"You must know that cyanide is highly toxic. Sodium cyanide itself is a white highly toxic substance. It will chemically react with water to release highly toxic hydrogen cyanide gas, which is the kind I smelled before. Bitter almond-flavored gas.” (Zhao Li’s)
As soon as these words came out, Dui Wang hurriedly asked concerned: "Then you...are you alright after inhaling it just now?"
Fang Yang waved his hand: "It should be fine."
"No!" Team Wang said with a serious expression, "You are not joking. Xiao Li hurriedly called 120, told the situation, and asked them to come over and have a look.
"yes!"
Fang Yang couldn't refuse to see Team Wang like this, so he continued to explain with an awkward smile: "The toxicity of hydrogen cyanide gas is 200 times higher than that of sodium cyanide. Once the concentration of hydrogen cyanide in the air reaches 0.3 mg per liter, Then, as long as a person takes a breath here, he will be poisoned and die immediately."
"Even if you wear a gas mask and carry an oxygen cylinder, if you encounter an accident, it is impossible to survive."
Hiss~~
This sentence scared them all.
Although they don't understand how much 0.3 milliliters per gram is, they feel that it shouldn't be much, and they can die from poisoning immediately, which is too scary.
Even the most venomous snake in the world can't kill people instantly!
Cheng Liang asked nervously: "That is to say, they are all here to wash the cave? This is too scary, can you be poisoned to death with a gas mask and an oxygen tank?"
Fang Yang nodded: "The poisonous gas is only one aspect. If it is bad, they can run away, but they didn't run away. Have you thought about why?".
