When it comes to the largest iron mine in China, many people think that it is not the Doujiashan mining area, Huangtang or Shuanglong mining area of Xudong Mining Group, but the Dongmenling iron mine. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

It now has identified reserves of more than 3 billion tonnes, making it the largest iron ore ever discovered in Asia. According to theoretical estimates, the reserves are likely to double, and further exploration is underway.

However, it is not like the three large iron mines in Xudong Mining Group, which are all amazingly high-grade rich ores, but the rich ore reserves are not much, and the reserves of general grade iron ore are amazing.

Therefore, if you talk about fame alone, Dongmenling Iron Mine may not be as good as Doujiashan Mining Area, Huangtang or Shuanglong Mining Area, but if you talk about the overall reserves of iron ore alone, it is currently the largest in China.

In order to identify this iron ore, the exploration team drilled a total of 17 exploration holes, of which 12 exploration holes were for iron ore, covering an area 4 kilometers long and 3 kilometers wide. Moreover, these exploration holes have produced complete iron ore cores from about 1,200 meters below the surface until 1,860 meters underground, and the deepest is still visible at 2,015 meters below the surface.

Iron ore grades between 25% and 62% have been identified from more than a dozen exploration holes, and the industrial type of the deposit is a mixture of magnetite and hematite, which is an extra-large iron ore deposit.

This iron ore mine began to mine iron ore a few years ago, but most of the iron ore grade is not high, 8 or 9 percent is the average grade of iron ore, after mining, it needs to carry out a series of processing, remove impurities, improve the grade, can be regarded as a finished ore.

Before the Great Iron Mine.

Xie Yushu, the chairman and general manager of this iron ore mine, frowned slightly, and behind him was a large iron ore processing plant, which was very large.

It's a pity that there is no treasure mountain, but the treasure cannot be collected!

Xie Yushu knows that the daily output of finished iron ore in the Doujiashang mining area of Xudong Mining Group is close to 300,000 tons, which is an astonishing number!

Their own iron ore reserves are also amazing, but when it comes to the output of finished iron ore, it is a little embarrassing, last year, only about 10 million tons, basically equivalent to the current production of a month in the Doujiashan mining area.

The main reason for the lack of production is that the iron ore grade is not high, which requires a series of processing of the mined iron ore ore.

In the first two years, Xie Yushu invested hundreds of millions of yuan after careful consideration to build the pellet processing plant behind him, coupled with the original iron ore processing plant, he believes that this year's finished iron ore output exceeded 20 million tons, there should be no problem.

Unfortunately, it backfired!

At the beginning of the construction of the pellet mine, the introduction of one of the world's mining giants, Lito Mining Group's pellet production technology, the money was also paid, the other party's technical information was also given, and a few foreign experts were sent over to pretend to give guidance, and later, foreign experts did not come.

Without foreign experts, the engineers and technicians of the Dongmenling Iron Mine were almost blind, especially according to the production technology of the pellets they bought, they could not produce pellets that could meet the requirements.

After countless failures, it finally became clear that Lito Mining Group had manipulated the technical data, and many of the key technical parameters were incorrect.

It's so damning!

Xie Yushu was so angry that he had no choice but to spend a lot of scientific research funds, carry out self-reliance, and organize his own engineering and technical personnel to tackle key problems.

At present, there is no mining company in the whole of China that has mastered the relatively advanced pellet production technology, and it is not easy to talk about tackling key problems by itself, and a lot of money and time have been spent, with little effect.

Sighing softly, Xie Yushu turned around and slowly walked towards the big pellet mine, another technical breakthrough is about to come to fruition, I want to take a look, how is the situation.

Xie Yushu pushed the door and walked into the office of Chief Engineer Tang Weipeng, and as soon as he entered, he obviously felt that the atmosphere was a little wrong.

In the office, in addition to Tang Weipeng, there are several technical backbones, but everyone is either sighing or frowning, and the atmosphere in the whole office is also very depressing.

Even though Xie Yushu had already felt the result, he still couldn't wait to ask, "How is the situation?"

Tang Weipeng said dejectedly: "Chairman, I... We've failed again, and I'm ......"

Failed again!

Xie Yushu's originally slightly frowning brows furrowed even deeper, and after thinking about it, he still encouraged, "Failure is the mother of success, so let's do it, I'll give you another 10 million scientific research funds, and everyone will try again." ”

Tang Weipeng nodded and said, "That's the only way, let's try again." ”

Then, Xie Yushu inquired about the recent technical research, and Tang Weipeng also made a detailed report, in general, there are mainly the following key technical problems that have not been solved.

The pellets produced this time are 3~5% lower than the imported grade, and the SiO2 content is 3~4% higher; affected by the particle size of iron fine powder, it is difficult to make pellets, and the addition amount needs to be more than 5%, and every additional 1% bentonite is added, the grade of the pellets is reduced by 0.6%.

In addition, there are the same problems as pellets produced by other domestic mining companies, that is, the pellets are roasted unevenly, the pellets have poor strength, high FeO content, and poor metallurgical properties.

The problems are not as many.

After listening to the report, Xie Yushu was shaken for the first time, even if he invested more money, it was estimated that it would be difficult to overcome this series of technical problems.

Ay......

Xie Yushu sighed softly, his heart was full of strong unwillingness, he spent so much money, so much manpower and material resources, and the result would be like this.

As if feeling Xie Yushu's mood, Tang Weipeng said: "Chairman, let's try again, maybe there will be a major breakthrough." ”

Everyone knows that this is not easy to say, Xie Yushu is not optimistic, there are too many technical problems that need to be overcome, but he gave up like this, thinking of paying so much before, he felt a strong unwillingness.

Unwilling!

"Bang!"

The door of the office was violently pushed open, and these backbone technicians were startled in their hearts, thinking in their hearts, who is this, such a cow, this is Chief Engineer Tang's office, and the chairman is also in the office.

It was Xie Yushu's assistant who came in, I saw him coming in excitedly, with a happy face, seeing this, Xie Yushu, who was a little dissatisfied, suppressed this dissatisfaction back, and asked in a deep voice: "Xiao Liu, is there anything wrong?"

Obviously, Xiao Liu's whole person was filled with joy, and he didn't pay attention to the slight dissatisfaction in Xie Yushu's tone, and said loudly: "Chairman, good news, great news!"

Good news!

Everyone was puzzled, just now, everyone looked sad, worried about the failure of the production of the pellet, Xie Yushu was even more unwilling and frustrated, where would there be any good news.

Seeing that everyone looked at themselves puzzled, the assistant Xiao Liu didn't pay attention to it so much, walked to Tang Weipeng's computer, said borrow the computer to use it, and then crackled into the website, opened the official website of the internationally famous journal, and opened the electronic version of the latest journal.

Everyone is even more puzzled, what is this for?

Assistant Xiao Liu said excitedly: "Chairman, haven't we been worried about not being able to produce high-quality pellets? Now all problems will be solved!"

What the!

Everyone in the office, including Xie Yushu, all raised their hearts with one heart, almost raised their throats, and all of them had an expression of disbelief, looking at Xiao Liu one after another.

Xiao Liu nodded affirmatively and said loudly: "Yes, it has been solved, Xudong Mining Group has officially announced to the entire mining industry around the world through this authoritative journal that they have mastered the world's most advanced pellet production technology and want to sell this technology to the outside world." ”

Yes!

What the!

The huge surprise, as if it hit Xie Yushu in an instant, it was simply like pushing aside the dark clouds to see the sun and the moon, and the willows and flowers were bright and another village, this turning point was too huge.

Several other backbone technicians were also happy, and even some of them almost jumped up, waved their fists vigorously, and said excitedly in their hearts, "Great, this is too powerful!"

Only Tang Weipeng is still more cautious, it is estimated that it is related to his technical background and rigorous character that he has cultivated for a long time, he pondered for a while, and said slowly: "Chairman, I don't know if this news is reliable?"

Where do you know, Xie Yushu didn't think about it, and said with great certainty: "It's 100% reliable, but it's Xudong Mining Group, and it publishes in such an authoritative international journal, so it can't be fake." ”

After speaking, I swept away the sad face just now, and in a blink of an eye, I sat in front of the computer with great interest and read the article about Xudong Mining Group.

The others, gathered around Xie Yushu, all stretched out their necks one by one, and their eyes were all fixed on the computer screen, watching intently, with full attention.

After a long time.

Xie Yushu finally finished reading this article and said happily: "Great, it is still the most advanced pellet production technology in the world, no matter how much it is, I must buy it." ”

Assistant Xiao Liu reminded: "Chairman, such a good technology, as long as the news spreads, it is estimated that many people will buy this technology, we have to do it as soon as possible." ”

yes, it has to be early.

Xie Yushu is well aware of the domestic iron ore grade and the desire of various mining companies for advanced pellet production technology.

So, he waved his hand and said loudly: "Xiao Liu, book a ticket immediately, I want to rush to Donghai City, in addition, Chief Engineer Tang, you also go with me, let's go buy this technology back." ”

Xiao Liu said excitedly: "No problem, I'll go to Ding for a ticket." With that, he ran out of the office in a hurry.

Seeing his assistant run out, Xie Yushu laughed.

………

The first person to buy pellet production technology from Xudong Mining Group was not Dongmenling Mining Company, but someone else.

As soon as the news came out, knowing that Xudong Mining Group was going to sell pellet production technology, many people were moved, and Xudong Mining Group also ushered in the first order.

Two hundred million!
