In the afternoon of the same day, according to Tang Feng's request in the morning, everyone went back to the United States to the United States, to the United Kingdom to the United Kingdom, to South Africa to South Africa, and to Argentina to Argentina. Tang Feng naturally wouldn't go all the way with them, and Tang Feng's itinerary had already been planned.

Tang Feng took Captain Tiger and the Iron Man, first flew directly to Oran, 800 kilometers away, and then drove to the St. Lawrence Copper Mine. Tang Feng still has thousands of tons of precious metal minerals in the star core, and the St. Lawrence Copper Mine is one of the places where Tang Feng chose to place some precious metal minerals.

After all, Tang Feng has not been to the St. Lawrence Copper Mine for several months, and this time he came here, the originally quiet St. Lawrence Valley has completely changed.

The valley is filled with the roar of large engines, driven by the construction vehicles that are trying to change the topography and topography of the St. Lawrence Valley.

In the middle of the valley, which was about three kilometers long, it was completely bare, all the trees were cut down, and in the corner of the small mountain range on the west side of the valley, a 50 by 50 meter pit had begun to take shape, and large excavators were constantly digging out the soil and rocks in this big pit, and then loading them into the back buckets of those large mine transport vehicles, and then transported by these big guys whose wheels were much taller than people.

Obviously, this area is the future heart of the St. Lawrence Copper Mine - the pit.

The St. Lawrence Copper Mine is a very shallow super high-grade copper mine, so open-pit excavation is the most cost-effective way to mine. This section of the valley is the area with the highest average grade and highest concentration of copper ore in the entire St. Lawrence Copper Mine, which is why this area was selected as the first pit.

And this big pit being dug is the starting point of the whole pit. In the future, there may be a super open-pit mine with a radius of several kilometers or even more than ten kilometers, and this super pit. It was from this big pit that it expanded outward and deep little by little.

In fact, in any open-pit mine on earth, the pits large enough to fit a small city, are dug out of such small pits little by little. For example, the Bingham Canyon open-pit copper mine in Utah, USA, started from a small pit and was slowly excavated into the largest open-pit mine in the world.

Tang Feng once visited the Bingham Canyon open-pit copper mine, which is located in Bingham Canyon, 45 kilometers southwest of Salt Lake City. This copper mine is also known as the Kennecott Open Pit Copper Mine.

The mine has been mined for more than 110 years since it was mined in 1906. Gold was found here, and gold was discovered here, so gold prospectors began to dig in the mountains, and later, large porphyry copper mines were found underneath, and it became the main copper producer in the United States in the 20th century.

In the twentieth century, the United States led the world in copper production by relying on this huge open-pit copper mine.

By now, the copper mine has been dug into a funnel-shaped open-pit with a diameter of 4,000 meters and a depth of 1,200 meters. Today, up to 320,000 tonnes of copper are produced here every year. And associated with a large amount of gold and silver. Moreover, this huge pit is the largest ever dug by humans.

Compared with this super cave, the peace diamond pit in Russia, the Kimberley diamond pit in South Africa, and the Chuquicamata-copper pit in Chile are all weak

In terms of the reserves at the St. Lawrence Copper Mine, perhaps in a few decades, there will be a copper pit larger than the Bingham Canyon open-pit copper mine.

"Regulus. Well done! Tang Feng wore a hard hat and stood on the edge of this pit that was beginning to take shape. Looking at the giant mining trucks that were working not far away, he said with a smile to Xuanyuan Gongsheng who was standing beside him.

Since the establishment of the St. Lawrence copper project, Xuanyuan Gongsheng has been staying here, assisting Christin, who came from Gravina Island, to preside over the work here, and for this mine, Xuanyuan originally planned to go home for the Mid-Autumn Festival. also gave up the plan to return to Huaxia, and plunged into this huge construction site with his head, and even ate and lived here, extremely dedicated.

And the exercise since these days has made this originally strong young man. Now he looks more burly, the most important thing is the kind of temperament on his body, which already faintly has the aura of a superior. It can be seen that this guy is obviously very willing to do this kind of work.

"Hehe, Brother Tang, it's nothing, anyway, there is still 8% of my shares in it, and these jobs are all I should do."

"Well, Xuanyuan, have you felt anything uncomfortable during these days?"

"That's not it." Xuanyuan shook his head, "Brother Tang, I have lived here for five years before, and I already know everything about the mountains, rivers, grass and trees here. Well, if there's anything out of the way, it's the complicated and headache-inducing management work. You know, Brother Tang, I used to be in charge of about twenty lumberjacks, but now I have to manage more than five hundred workers, and if it weren't for Mr. Albert to help me, I really don't know how to manage so many people. ”

Tang Feng turned his head, looked at Xuanyuan and said, "Brother, if I were you, then I would take a certain amount of time to dedicate myself to learning professional knowledge in business management and other aspects." It may seem like it's useless, but in practice, you can find that what you learn from books is actually quite useful. So, brother, if you really want to become a qualified manager and superior in the future, I suggest that you start learning professional knowledge in this area from now on. ”

Tang Feng said with a smile: "It's like me, unless I'm really busy, I will spare one to two hours every day to learn the knowledge in the books." Personally, I find it very useful. ”

Xuanyuan nodded, let out a long breath and said: "Brother Tang, I listen to you, in fact, I have recently started to get in touch with this kind of thing, and Mr. Albert also recommended me a few good professional books, which I have been reading now." After this period of time, I plan to take a training course and learn management systematically. ”

Tang Feng smiled: "It's enough for you to have this heart." ”

Just as the two were talking, a huge figure slowly drove over from a distance with bursts of roars, Tang Feng's eyes bulged, and he said in surprise: "Hold a big grass, what is this?" Why is it so big? (To be continued.) )
