After catching up on sleep in the guest house, everyone came to the cafeteria on time at six o'clock for dinner.

Unlike the northerners, who pay more attention to the form, Zhou Changqing is not so complicated, there is no welcome ceremony, speech or anything, and the canteen also adopts a buffet mode, and there is no forced drinking, which makes Zhong Bai feel extremely comfortable.

Zhou Changqing also has studied abroad experience in MD, so he knows the importance of doing a good job in the treatment of employees, and the rice in the canteen is all Northeast rice, which has a special fragrance when chewed, which is countless times stronger than the indica rice in most factory canteens.

More than 20 people sat at three round tables, there was no distinction between the guest of honor, Zhong Bai happened to sit near Zhou Changqing and Xu Guangxian, and heard the conversation between the two while eating.

"Guang Xian, I see that the average age of the comrades you brought this time is still relatively young, how do you feel about their level?"

"The average level is much better than that of two years ago, and there are still some comrades with solid theoretical knowledge and a certain ability to think." Speaking of this, Xu Guangxian subconsciously glanced at Zhong Bai and Yan Yutian in the distance: "Some are cadres in the system, and some are the backbone of private enterprises, but I feel that they should usually grasp the study of knowledge very tightly." ”

"That's good! Hey, Guangxian, don't you know the hardships of this enterprise, and the funds invested in the experiment this month have exceeded 100,000 yuan......"

"How's it going?"

"What else? It's not a big breakthrough, it's just a lot of scrap and some data records......"

Speaking of this, Zhou Changqing's face became gloomy, and his voice became much quieter.

Zhong Bai couldn't hear what the two of them were talking about later, but the two sentences just now still made Zhong Bai feel that at least the current operation of this company may not be as stable as it seems on the surface.

After the meal, Zhong Bai originally thought that there was no arrangement, but Zhou Changqing offered to take everyone to the workshop to take a turn first to learn about the entire production line of Ningyuan Rare Earth Metallurgical Plant.

This metallurgical plant uses rare earth concentrate as raw material, processed by acid production line, and then enters the high-temperature concentrated sulfuric acid roasting and water leaching process, and then extracts rare earths.

When it comes to the extraction of rare earths, the "cascade extraction method" taught by Academician Xu Guangxian will be used to obtain rare earth chloride, and then hydrochloric acid system extraction will be carried out to obtain neodymium oxide.

The whole process was quite complex and comprehensive, and while everyone was surprised by this, Zhong Bai only sighed in his heart.

That's because the upstream and downstream division of labor in Huaguo's rare earth industry in the 80s was not clear enough, and it was originally supposed that several factories would have produced so many links in 2020.

But now, you can only take this kind of big package form from the beginning all the way to the end, correspondingly, the more links you have, the more equipment and related personnel you need, and the higher the requirements for technical mastery.

Once things get complicated, the odds of success are greatly reduced.

Zhou Changqing hadn't said anything at the time of the introduction, but after the internship officially started the next day, Xu Guangxian was not so polite.

"As you can see, after the processing of this acid production line workshop, we can enter the next step of high-temperature concentrated sulfuric acid roasting and water immersion."

"In the case of the current general use of high-temperature concentrated sulfuric acid roasting method to treat rare earth concentrate, due to the high-temperature roasting process produces a large number of sulfur-containing, fluorine, strong acidic waste gas and radioactive waste residue, not to mention serious pollution to the environment, and it is also difficult to recycle, can only be continuously stacked, which has caused a lot of pressure on the enterprise itself, because it needs to pay a high cost of environmental pollution control......"

Xu Guangxian gushed about the shortcomings of the current production line, if it was put in the external publicity, he would never say this, and Zhou Changqing would not either, but today these students are all outstanding talents selected by themselves, and they are the comrades who want to save this rare earth metallurgical plant in the turmoil in the future, so he doesn't mind showing these ugly backgrounds first.

"So, now let me ask the leaders of the two groups, do you have any good opinions on this disadvantage?" After speaking, Xu Guangxian entered the Q&A session, and looked at Yan Yutian, the leader of the first group, and Zhong Bai, the leader of the second group.

Of course, he didn't expect to really solve the actual problem through this kind of Q&A, but mainly wanted to understand the thinking mode of the two people through it - that is, after encountering specific production problems, if you are the technical backbone of the factory, how would you give advice to the decision-makers?

After Yan Yutian and Zhong Bai glanced at each other, the former opened his mouth first, after all, he was a little older, and the first group was also in front of the second group.

I saw Yan Yutian from Lingnan Yuanfu Rare Earth New Materials Company thought for a while, and slowly said his opinion: "I think that under the premise of using high-temperature concentrated sulfuric acid roasting and water immersion process, it is difficult to improve the process itself, this technology has been used on a large scale at home and abroad for more than ten years, and everyone has not been able to solve the shortcomings that Academician Xu said before, so if you want to save enterprise costs from the perspective of saving costs, my personal opinion is, It is necessary to communicate more with the local ZF and relevant departments. ”

"Do communication? How to communicate? Before Xu Guang could speak first, Zhou Changqing, the factory director next to him, who had been silent, frowned and asked questions first.

"The internal information we saw in the morning showed that the stacking of waste residue in the factory was based on the principle of proximity, and it was stacked in an orderly manner in the area arranged by the local ZF, and the charging standard was of course in accordance with the existing one. In the case of many related enterprises in the Baiyun Obo mining area, there is no room for negotiation. After all, the Mombasa-Nairobi region also manages this area more strictly. Yan Yutian's eyes rolled: "But as far as I know, the border of the adjacent Bac Ha Province is sparsely populated, and there are also a large number of places suitable for stacking these radioactive waste residues, and the charging standard on their side should also be low." The factory may wish to consider a way to transport these radioactive waste residues to the side for stacking on the basis of increasing a certain amount of transportation costs and communication costs. ”

"In this way, it not only relieves the pressure on the local area, but also increases the income of the counties and cities on the border of Bac Ha province to a certain amount of stacking fees, and the cost of the enterprise is also reduced, which can be described as killing three birds with one stone." In the end, Yan Yutian's face showed a smug expression.

To put it simply, the current situation is that the waste materials in the production process of Ningyuan Rare Earth Metallurgical Plant pollute the environment, and they must be stacked locally in large quantities in accordance with environmental protection standards, and the enterprises can not afford this cost, so they will transfer it to the neighboring Bac Ha Province, where there are fewer related enterprises, so the environmental protection cost is low!

Although this idea was improvised by him, it was not a slap on the head out of thin air, but a precedent, although it was not in the same industry.

In Lingnan Province, where he is located, the economy is developed and there are many industrial enterprises, while the next door Jiangxi Province is much worse, so some high-polluting enterprises in Lingnan Province have also used the above methods to transport waste materials to Jiangxi Province for processing, and finally everyone is happy.

Xu Guangxian did not comment on this answer, but looked at Zhou Changqing.

Zhou Changqing frowned and was about to say something, but he heard Zhong Bai next to him say something coldly.

"What is this called communication? Isn't it just to transfer the pollution? Isn't that all the land of our country? Moreover, in Bac Ha Province, they do not have relevant intensive enterprises, and the future pollution reduction treatment will be more difficult and more costly. ”
