In the world, the scenery of life is not all mirrors and flowers, nor is it all flowers, any life is a small universe, and it has its own time; Any life is a book with its own story; Every life has a lonely journey, and it has its own unique life and life value.

The sacrifice ended in a ridiculously comical dance, Paul drove away without coming to our shed, and Zhu Yong and the others began to talk about the ritual we had just had, muttering that Paul was a charlatan, abducted and deceived, what a mess of the sacrifice, all fucking bullshit!

Wei Ergou didn't refute them, but ran to the excavator to look, and when he saw the group of black crows leaving, he happily ran back to the shed like a lottery winner and shouted, "Hakura Matata!" The crows are gone! "Lao Li and Lao Cao went to the excavator to confirm it, and they also came back to tell us that the crow had indeed left. There are some things that you will never feel the incredible shock if you don't really experience them! If you want to ask me whether I believe in those evil things, I can sue you very responsibly, I still don't believe it, but I don't dare not believe it!

Wei Ergou beckoned everyone to prepare to start work immediately, before the start of work, he took the lead and incense the statue of Lu Dongbin on the wall, he is now worshiping both the gods of China and the shamans of Ghana! Everyone was skeptical, Lao Cao, Xiao Cao, Lao Wu and the black workers moved the pump equipment, and Zhu Yong started a large generator to connect the electricity in the mine; Lao Li checked the excavator, put butter on it, and added hydraulic oil; Wei Yiyun and I also helped with what we could. After more than an hour of preparation, the construction site began to be busy again, the smoke emitted by the excavator operation filled the entire mine, and the black workers commanded Lao Li's excavator while draining the water, and the whole construction site was in an orderly manner, and it seemed that everyone rekindled their fighting spirit and hope.

After more than three hours of work, it seems that there is indeed more gold sand filtered by the gilding tank than before, and Wei Ergou checked it several times and gave us a thumbs up to indicate that the output has increased.

Xiao Cao and Hei Gong respectively held high-pressure water cannons to wash away the sediment poured by the excavator into the gilding tank, and this water was also specially dug in the reservoir next to the mine, and it was slightly clear after precipitation. After the high-pressure water washes into the soil, the bean-sized clay is filtered from the first layer of gilding trough to the second layer of chute, filtering step by step, filtering out the soil, and finally into the bottom layer of the gold washing blanket, leaving a small amount of sand, gold and other minerals mixture. Cao and Wu and Donai constantly check the eight water pipes, all connected to sand pumps, four of which are mainly pumped from the pool to wash the dirt placer; The other four pump the sewage deposited underneath during the scouring process into another cesspool, which will be used as the next day's clean water pool after a night of sedimentation. During the whole process, Xiao Cao, who was standing in front of the gold placer and holding a water gun, was the most tired and hardest, wearing a heavy one-piece protective suit, and the weather was so hot, and there was basically no wind blowing under the mine; In less than an hour, Xiao Cao and Lao Cao and Lao Wu will exchange, and the other three water guns will be handed over to the black workers, who are very experienced in assisting in the scouring operation.

Wei Ergou would walk to the edge of the pit to check whether there was a collapse in the mine, and then he would go to the bottom of the gilding trough and scoop up a handful of gold sand with his hands to see the scouring efficiency and gold content. Wei Yiyun wore a pair of black oversized sunglasses and followed behind Wei Ergou, Wei Ergou explained various operations to him, and it could be seen that Wei Ergou wanted to train Wei Yiyun to become a qualified placer gold mine manager.

At noon, everyone simply ate a few cassava and eggs in the mine and continued to be busy, the day ended in the busy, the more busy the more I felt that time was fast, Lao Wu brought back a large bucket of gold sand, everyone had a smile on their faces, it can be seen that today's output is much better than last week's situation, even I don't understand the gold mine, I feel that everyone's mood is so happy, as if the gold mine began to celebrate the festival.

Lao Wu didn't care about eating and put the gold sand into the sandalwood washing bucket, the washing gold bucket looked more like a dustpan, Lao Wu sat next to the iron plate welded pool, holding the gold washing bucket in the pool and gently swaying, so that the sand fell into the pool from the sandalwood dustpan, which is the use of different buoyancy principles of sand and gold density in the water, and the pool is generally covered with a gold blanket to prevent gold from accidentally falling into the pool.

When the dust gold poured out into the iron can, Lao Wu took out a bottle like eye drops, and I stood behind Lao Wu and asked him, "Lao Wu, what is this?" ”

"Oh, mercury!" Old Wu Tou didn't reply, and dripped several drops of mercury from the bottle into the iron can, and the mercury covered the entire layer of gold dust particles in Le.

"What is this for? Why do you need to add mercury? I bent down to look at the particles in the small tin can and asked Lao Wu softly.

"It's a shame that you're still a college student! Don't you have any common sense? Mercury can refine placer gold, because the density of mercury is greater than gold, so if the sand gold is placed in mercury, the gold will sink, and the impurities will float on the surface of the mercury, so as to achieve the purpose of separation, don't you understand this physical knowledge? "Lao Wu gently shook the small tin can and laughed at me for not knowing the principle of mercury to make gold.

"Huh? Didn't you make gold out of some kind of cyanide? I used to watch movies or read books and said that I used to use cyanide. "I didn't understand and continued to ask Lao Wu, and Lao Wu didn't know how to answer me for a while.

"Nerd! Cyanide is contraband, where did a small mine like ours come from, and the money to buy cyanide is still the money to dig up gold! In addition, cyanide is mainly used for rock gold refining, which is a chemical method, using cyanide to convert gold from ore to liquid form and adsorb into cyanide. And our placer gold production is only how much a day, and the placer gold is not so complicated, and the gold itself does not need to be separated, just some sediment and a little other metal mixture, which is simple and convenient with mercury, and the price is also cheap. Wei Ergou answered my question completely behind my back.

"It's still Mr. Wei's detailed answer, a professor-level answer!" Lao Wu gave Wei Ergou a thumbs up.

"Oh, I see! There's a doorway to the line! I smiled at Lao Wu and Wei Ergou.

"Lao Wu, hurry up and alchemy, look at today's output!" Wei Ergou patted Lao Wu on the shoulder.

"Huh? What's next? I asked Wei Ergou.

"Real gold is not afraid of fire, of course, it uses fire to dissolve gold into gold water!" Lao Wu hurriedly replied to me, "You say that I have learned something in college students, don't you have any common sense?" ”
