"Is there really such a new technology?!" Seeing that Zhong Bai was so determined, Hu Yanjun couldn't help but exclaim.

He is also the deputy director in charge of mine metallurgy, not to mention, he still has a certain degree of understanding of the main excavation and extraction technology of rare earth concentrate in Baiyun Obo mining area, "water immersion method".

The existing water immersion method is a rare earth concentrate production technology developed by RB more than 10 years ago and promoted on a large scale, and it has been introduced into China for several years, but now RB has long been abandoned in China, because of the "three wastes" produced by this traditional method - that is, there are too many waste gases, waste water, and waste residues, which seriously pollute the environment.

In the early 80s, Huaguo did not pay any attention to environmental pollution, and if it was replaced by other industries that could not earn a lot of foreign exchange, and produced such a serious "three wastes" as the flooding method, I am afraid that it would have been stopped long ago.

However, rare earth is the lifeblood of the Baiyun Obo mining area, and it is also the source of a large amount of foreign exchange in the autonomous region, and it is impossible to rush to shut down because of the "three wastes", so the local government and the higher authorities have been playing in the middle, but the actual result is that the annual rare earth concentrate production and export volume of the Baiyun Obo mining area is still slowly increasing.

Last year, the autonomous region organized a group of experts from the autonomous region to go to Beijing to link up with relevant departments and research institutes, and also invited some European professionals to try to improve the existing "flooding method," but there was almost no effect.

Now when he heard Zhong Bai say that there is a brand-new technology, which can also greatly reduce the emissions of the "three wastes", Hu Yanjun couldn't hold it back: "Xiao Zhong, tell me what kind of technology it is?" ”

"I can't say it in a few words, and this is not the place to talk about technology......" Zhong Bai glanced at Zheng Jincai and reminded: "Director Huyan, when we finish the work of soliciting opinions, I will take the time to exchange technology with you." Besides, whether this training program is adopted or not, you still need to make a decision! ”

"Oh, look at my anxiousness, I almost forgot about my serious work, haha!" Looking at Zheng Jincai, who was already in a daze, Hu Yanjun slapped his head and said happily to the other party: "Director Zheng, it seems that you have a hand in cultivating talents!" Geng Dali in your bureau is good, and it is not easy to come up with a training program that combines Xiaozhong's new technology! Such an excellent talent, you have to pay close attention to it! ”

Geng Dali's heart was overjoyed when he heard this, and he looked up at Zhong Bai again, and Zhong Bai quietly gave him a thumbs up, and the meaning was self-evident!

Hu Yanjun looked at his watch again and said: "Director Zheng, more than a dozen comrades have come before, and now the opinions should have been solicited almost, if there are no other suggestions, then your bureau team will hold a meeting first, and make the plan proposed by Comrade Geng Dali into a document and prepare for implementation!" Then Director Ye and Xiao Zhong, let's go back to the guest house first and discuss it again. ”

After that, Hu Yanjun got up and took Zhong Bai and Ye Xing away, and Geng Dali, who was in charge of logistics, followed him out!

In the office, only Zheng Jincai, who was at a loss, seemed to be a little incredulous about what had just happened, and muttered to himself: "No, the situation was so grim at the morning meeting, this is ...... That's it? But is the money for this training from the bureau or from the department? Wait a minute! ”

When Zheng Jin came back to his senses and chased after him, the four of them had already gone downstairs and walked away, so he could only lie on the railing of the corridor and look at his back and sigh......

……

After Geng Dali sent the three of them into the room, he was so excited that he couldn't even find the south, south, west, and northwest, and stood alone at the door of the guest house in a daze.

The scene that happened before leaving the office just now is still vivid, recalling every detail, Geng Dali couldn't help but raise the corners of his mouth slightly!

Unless you are a fool, no one will not hear Deputy Director Hu Yanjun's affirmation of the training course plan and himself!

Especially the deputy director's sentence "You have to attach great importance to such an excellent talent", or said to Director Zheng, basically announcing that his promotion is a certainty!

As a full-level office director, there is no suspense about the further promotion to deputy director.

As for whether he can reach the "one-step approach" described by Section Chief Zhong to himself, and be promoted to director of the bureau without exception, Geng Dali really has no bottom in his heart!

After all, this kind of thing happens too few times in the system, and there has been no example of this within the Mining Industry Bureau since its establishment!

"Calm down, I want to calm down......" Geng Dali was blown a little hot by the heating in the hall, and took the initiative to open the door, and when he was blown by the cold wind outside, he felt a lot calmer.

He pondered carefully, Deputy Director Hu Yanjun's affirmation of his plan, although this plan can stabilize the situation plays an important role, but more importantly, in the plan, Section Chief Zhong Bai proposed to train workers in "new technology".

Without "new technology", this training can only be reduced to a superficial link, and Geng Dali is still very sober about this.

Geng Dali, who was pacing in the cold wind, didn't feel the slightest cold, but kept slandering in his stomach: "Section Chief Zhong is well versed in various operating rules in the system, and it all depends on Section Chief Zhong to engage in this new technology, and I don't know what the 'timely rain' he told me to wait for last time is?" ”

But what Geng Dali didn't know was that Zhong Bai was in the room at the moment, and he was drawing an extremely grand blueprint for the rare earth industry to Hu Yanjun, deputy director of the Industrial Department of the Autonomous Region!

The room in the guest house was filled with smoke, and Hu Yanjun stood at the table, watching Zhong Bai in front of him sitting on a chair, scribbling on a piece of white paper and explaining to himself.

"It's hard to name this new technology exactly, and I think of a closer term called 'full recycling technology', which is detailed below."

"In the wastewater treatment process, we can first recover and separate all the mixed acids containing sulfuric acid and fluorine in the tail gas, first form 70% sulfuric acid and 15% fluorinated acid, the total recovery rate of acid is greater than 99%, part of the 70% sulfuric acid is used back to the production of washing residue, part of it is prepared into 86% sulfuric acid or processed into 93% sulfuric acid for production and roasting, and the remaining 15% fluorinated acid is the main raw material for the recovery of fluoride salt."

"Its main process is to realize the enrichment of more than 40% of the acid in the tail gas through the exhaust gas circulation cooling facility, and then the enrichment acid is realized through the vacuum concentration process to recover 70%-93% of the sulfuric acid and the separation of 15% fluoric acid."

"Through these two links, we can reduce the current wastewater pollution of rare earth concentrate plants to meet the environmental standards of the European Community, and of course, the domestic requirements are lower, which is no problem."

It is impossible for Zhong Bai to decompose this kind of more professional content in detail, but Hu Yanjun, who graduated from a secondary school, can be regarded as basically understanding, and he asked again: "What about the exhaust gas?" ”
