When Zhang Yi said this, he also thought it through.

The words at the wine table are usually patted on the head and talked nonsense, on the surface they are called brothers, and who cares who you are afterwards.

This time I met Director Yang at the dinner was also accidental, Director Yang encountered technical problems he could have ignored, should eat, drink, anyway, it has nothing to do with him, indiscriminately said that it can solve the problems that many technical personnel can't handle, it is easy to make people have a bad impression in their hearts.

However, Director Yang is not familiar with him, and he doesn't know which company is still the director of the unit, but judging from Wei Ming's attitude towards him, Director Yang's status should not be low, at least higher than Wei Ming.

This made Zhang Yi's heart open, he wanted to get a piece of the persimmon bamboo garden, but he had no foundation here, his money was invested in the smelter, and there was nothing else to use except for a lot of technology in his hands.

And he also understands that if an outsider wants to enter the industry that has been in business for many years and has a mature interest chain, he must rely on talents with a certain status in the industry.

Since Director Yang has encountered technical difficulties, he might as well start from here to help him, and at the same time create an opportunity for himself.

After Zhang Yi's words were spoken, the scene was also a little silent, and Song Lin and several employees of Tianshui Mining did not interject, thinking that Zhang Yi was still too young and did not speak through his brain, this problem is so easy to solve, and the whole company still has to worry about this?

Even if you are a technician in a smelter, can a smelter be the same as a mineral processing plant? One is engaged in metallurgy and the other is engaged in mineral processing, and they are two completely different professions.

Song Lin and the others originally wanted to joke a few words, but thinking that Zhang Yi might become the company's big financier and generate income for the company, if he offended him, it would not be easy to mix in the future.

Seeing Zhang Yi say this, Wei Ming didn't believe that Zhang Yi could solve this problem at this level, and was worried that Zhang Yi would offend Director Yang by saying nonsense, so he hurriedly said: "Brother Zhang, this technical problem is not difficult, Director Yang has been tackling key problems with the entire technology center for a month, and there is no progress yet, I'm afraid it won't be so easy to do, right?"

The words also threw out the technical problems, Director Yang and they worked overtime day and night for a month, it must be that the technology is too difficult, it is not a problem of Director Yang's level, Zhang Yi does not need to say more, and another is afraid that Director Yang will be more serious, Zhang Yi is young and vigorous, and it is not good to make trouble.

Zhang Yi said this, whether you believe it or not, in short, he will not blush, pull his neck and have to prove anything to others because he doubts him, his emotional intelligence is not so low.

"Boss Wei and so on. Before Wei Ming's words fell, Director Yang seemed to come back to his senses and interrupted Wei Ming's words with a wave of his hand.

He was still thinking about whether the selective grinding that Zhang Yi said was feasible, and he had only heard of this technology, and some scientific research institutes engaged in mineral research did have this technology.

But he didn't, and neither did his technology center team, seeing Zhang Yi's determined appearance, and when he contacted Zhang Yi before, he didn't think he wanted to be the kind of person whose emotional intelligence was so low that he talked nonsense.

Could it be that Zhang Yi is right?

There is a specialization in the art industry, don't look at Zhang Yi's young age, Director Yang is not the kind of person who is immutable and pedantic, if it is really helpful to the company, he is willing to sit down and discuss the technology of selective grinding with Zhang Yi.

"Brother Zhang, can you tell me more about the selective grinding technology you just mentioned?" Director Yang turned his head to Zhang Yi and asked, this attitude was obviously lowering his stature, and he didn't regard Zhang Yi as a young man who had just entered society.

Seeing Director Yang ask this, Zhang Yi knew that he had already taken this matter seriously in his heart, and if Director Yang had that disdainful expression, then he would not continue to speak.

In fact, the problems encountered by Director Yang have also been encountered in many large mines, and it is a normal phenomenon for ore to change layers, but for good quality ores, even if they are replaced, the two ore layers are still very good ores, and the grade will not be low.

However, what Director Yang encountered happened to be a process from good ore to bad ore, which required to improve the grade of concentrate through technical level, otherwise it would be difficult to carry out follow-up smelting.

Zhang Yi said directly: "If we want to improve the grade of concentrate, we must analyze the microstructure of the mineral, that is, we must consider where the root cause of the problem is. ”

"The structure of a mineral depends on the individual particles within the mineral crystal, that is, the chemical bonds between atoms, ions and molecules. Different structures determine the mechanical properties of various minerals. ”

"Minerals with atomic bonds are hard, physically stable, and the most difficult to grind, such as diamond. ”

"Ionic crystals are brittle when stressed, and most minerals in nature are ionic bond minerals, so most minerals are hard and brittle in mechanical properties. ”

"The molecular bond energy is the weakest, and the hardness of mineral crystals is also very low, such as elemental sulfur, realgar, and galena, which are the easiest to crush. ”

"The minerals in nature are very complex, and the mechanical properties are not the same, and the crushing effect is good only when the crushing force is applied to the minerals and ores. ”

"Regardless of the mechanical properties of the crushing object, the same crushing method will not get a good crushing effect, because there is no targeting. ”

Seeing Zhang Yikou narrating the microscopic properties of minerals like a hanging river, Song Lin and the others were surprised.

They have never heard of these professional terms, and it feels like those who specialize in mineral scientific research will study this kind of thing, and they will not pay attention to these if they are engaged in sales and marketing, but Zhang Yi really understands this technology, and Song Lin and others immediately put away their contempt.

Wei Ming didn't expect Zhang Yi to say such a big deal, he also thought that Zhang Yi was a Yanei who only knew how to mix and eat, and he specially went to the mining area to fish for outside water, and took the money from the smelter to squander.

At this time, the most anxious person is Director Yang, he is a genuine technical expert, of course he knows what Zhang Yi is talking about.

But Zhang Yi seems to have just said what the problem is, but he didn't say a specific solution?

But looking at it like this, Zhang Yi seemed to be able to solve it, and Director Yang said anxiously: "Brother Zhang, I understand the problem you said, can you tell me if there is any good solution?"

At this time, Liu Rui has been much more sober, looking at this Zhang Yi seems to be able to solve this technical problem, but think about it, can this kind of problem be Zhang Yi? Even such a difficult technology as tungsten and molybdenum separation can be solved, what is it to improve the concentrate grade, and can it be compared with tungsten and molybdenum separation?

Liu Rui patted the table lightly and said, "Director Yang, don't worry, my junior brother said that it can be solved, then it will definitely be solved, my junior brother knows a lot, and he knows all kinds of techniques." ”
