Gang Leader Yang arrived in the Northeast a week later, and Luo Tian immediately flew over. This time, he was alone. The situation was different from before. Someone had to be in charge of the company. Old Luo was in charge of the inside and he was in charge of the outside.
It is already a matter of clear division of labor.
In this round, Gang Leader Yang invited Luo Tian to visit the gold mine. In this world, there is probably no metal that can intervene in human life again and again in the long history of history. In the late Spring and Autumn Period, gold
It began to circulate. In the late Warring States period, the circulation of gold was very common. Even palace rewards and court bribes were all made of gold. During the Qin and Han Dynasties, there was a huge amount of gold. However, by the end of the Eastern Han Dynasty, this gold suddenly disappeared without a trace.
trace.
In the late Eastern Han Dynasty, the royal family and wealthy families were frightened by the power of the Green Forest Army, the Red Eyebrow Army uprising in the late Western Han Dynasty, and the Yellow Turban Army uprising in the late Eastern Han Dynasty. To prevent unexpected events, they fortified the walls and cleared the country and hid a large amount of gold and other treasures. However, the peasant army was invincible.
, catching the officials and wealthy people off guard, some were killed, and some fled but often died in other places. Therefore, the huge amount of gold they secretly hoarded was lost. Although later generations occasionally discovered gold hoards in excavated Han Dynasty ruins.
, but it is believed that huge amounts of gold are still buried deep underground and have never seen the light of day.
After that, gold once again became the king, and to this day, there are still theories about gold in troubled times and antiques in prosperous times, which shows how much people trust gold, a solid currency.
Luo Tian had no problem with identifying gold, but his understanding of gold mines was all improvised. Some of the gold extracted comes from placer gold, and some comes from vein gold. Since the 1970s, the output of vein gold has remained at 75
% ~ 85%, and placer gold accounts for 15% ~ 25%. Since the 1990s, due to environmental factors, the share of placer gold production has further declined, and now vein gold production is the main production.
There are records about gold mines in our country very early: Guo Pu of the Jin Dynasty mentioned in "Jiang Fu": "Underneath are the gold mines and gravels, and the clouds are fine and silver." "Abhidharma Kusa Lun"#
"8226; Distinguishing Intelligent Products" also said: "It is named after the reason, such as the gold mine is named Dejin." In the Qing Dynasty, Wu Rulun's "Li Wenzhonggong Shinto Stele" also mentioned: "Mining Tangshan
The coal mines and the Mohe gold mine have both made outstanding achievements and are well equipped both internally and externally."
It can be seen that the mining of gold mines has its origins in history. According to Gang Leader Yang, who was there first, he said on the phone that the gold mines in the Northeast this time were placer gold deposits.
This placer gold deposit is a primary gold deposit exposed on the surface. Due to mechanical and chemical weathering, the gold-bearing veins or gold-bearing parent rock are gradually broken into cuttings and gold particles. Then, the transport and sorting effects of external forces
Under the conditions, minerals with larger specific gravity (such as gold particles) are deposited on hillsides, river beds, and lakeshores, forming a certain concentration. Those with industrial mining value are called placer gold deposits.
Mining is about to start now, and the quality of the first pot of gold will directly determine the future. This is why Gang Leader Yang came here in a hurry, and also made Luo Tian rush over to witness this critical moment together.
Luo Tian was also sweating in his heart. Although he thought there was no big problem, the positioning of Tianyi Jewelry is now at the stage of building brand value. If the gold source is improved, the product cost will be reduced and the quality will be improved.
Yes, this is an excellent reflection of brand value, but if it is not good... all the effort you have put into traveling from Tokyo to China will be in vain, and the value of the agreement will not be great.
After closing his eyes and taking a nap, Luo Tian heard the message from the plane that it was about to land. It was a mule or a horse. Just take it out for a walk.
Gang leader Yang came with his partners to pick up the plane. Luo Tian felt a little embarrassed to be at this far distance: "You are too polite. In fact, I can go there by myself. We are busy now."
"It doesn't matter, we will be more confident now that you are here." Gang Leader Yang said this as if Luo Tian was here, and the quality of the gold mined in this gold mine would be better.
Gang Leader Yang’s partner is known as Brother Lu, and his real name is Lu Ming. He is the son of Gang Leader Yang. In Gang Leader Yang’s words, he is the kind who wore a pair of crotch pants and played in the mud when he was a child. Judging from his appearance and conversation, he has some temperament.
, which formed a strong contrast with Gang Leader Yang's gangsterism. Luo Tian felt that such a pair would be more likely to accomplish great things. Nowadays, in addition to rules, there are also unspoken rules. This is already a matter of appearance.
After sitting in Lu Ming's car, Lu Ming could not hide his excitement: "I didn't expect that the matter was won so smoothly. It was Lao Yang who came forward so powerfully."
"I couldn't have done it without you. The brothers in the gang are all counting on this gold mine to wash their hands."
Luo Tian was a little happy: "If this really happens, it will be a real golden basin to wash hands."
"Yes, success or failure will be tomorrow." Gang Leader Yang suddenly became nervous: "Luo Tian, according to you, will it happen?"
"Now that we haven't seen the gold ore, it's hard to tell. By the way, what method are you going to use to extract gold?" Luo Tian is very concerned about this. If the method they use is too old and too traditional, it means they are not determined to do it.
This is a big deal. This is very important. This kind of cooperation is bound to not last long. We must be as dedicated as the raw material dealers of diamonds and have the determination and methods to become the industry leader. Only in this way can the two companies achieve the most perfect cooperation. Luo
Tian looked at the back of Lu Ming's head and felt a little worried: "Are you going to use a single mercury amalgamation method?"
This single mercury amalgamation method is the most traditional. This process is suitable for processing quartz vein primary deposits and oxidized ores containing coarse-grained gold. The mercury amalgamation method for gold extraction is an ancient and common gold separation method. In the modern gold industry
In production, the mercury amalgamation method still occupies a very important position. Since gold mostly appears in a free state in ores, some gold particles in various ores can be recovered by the mercury amalgamation method. In the gold separation process, amalgamation is used to recover gold particles.
The mercury method recovers part of the gold particles in advance, which can significantly reduce the loss of coarse gold particles in the tailings.
The single mercury-mixing gold extraction method has a simple process, easy operation, and low cost. However, mercury is a toxic substance and is very harmful to the human body. In modern society, this process violates human rights, and enterprises are most prone to labor conflicts.
"No, what method to use to extract gold? I will wait until the personnel from the relevant departments come to inspect the gold mine in the afternoon before deciding. I will not blindly adopt a certain method." Lu Ming's words sounded a bit reliable: "The results will be available soon.
