Pyrite slag is the residue left after the sulfuric acid is produced from pyrite by the contact method.

The contact method is the simplest method of preparing sulfuric acid, which is commonly used in the world of that side, which is to burn pyrite and coke in a roaster, keep burning, and then extract the burned sulfur dioxide, add water and it will be alive.

As for the process of dust removal and purification, catalytic reaction, emission reduction and efficiency increase, it is needless to mention.

In short, Hantang Group is like a mirror in his heart, the pyrite contact method to produce sulfuric acid is the right way, and the pure sulfur production method at the beginning can only be said to be an emergency, so the output is too low!

The key equipment for the processing of sulfuric acid by the contact method was brought, but Li Ziqiang was still a science and engineering student, and he could understand what he said at that time, and he didn't dare to suppress it too hard.

Pyrite slag itself contains 50% iron and other metals, which should be regarded as a material with a high comprehensive utilization rate, but because it contains about 3% ineffective sulfur and 47% gangue, it is difficult to be directly used in ironmaking.

Except for a very small part of the world that is used for building materials, the rest is left to be dumped on the riverbed or encroached on a large amount of land. Let's talk about the benefits now.

Technician Xu Zhiming whispered to everyone: "Have you ever seen the place where those waste materials are placed? It's the surface of Mars......"

At that time, Founder Zhengguo, a technician who had worked as a technical director of a smelter, temporarily served as the leader, and he took over and said: "I've seen it, Lao Xu, red, brown, yellow -- if the wind blows-"

The small smelter where Xu Zhiming's technician works carefully selected a batch of materials with high iron content from these unexpensive wastes by strong magnetic method, and then made great efforts to carry out the sulfur removal process, and after sintering, the result was really made into pellets.

At that time, the blast furnace of the small smelter was 30 cubic meters, and it was close to the late stage of service, there were only two hot blast furnaces, the hot blast pipes were poor, and the air temperature fluctuated greatly, which often made the blast furnace in a situation of low air temperature, high metallurgical strength, low load and high coke ratio...... Every time the on-the-job operation made Xu Zhiming, the squad leader in front of the furnace, worried, for fear of any accidents.

Of course, not such a blast furnace...... Nor will they be forced to find a way to use pyrite slag that doesn't cost anything.

The small boss also let go, and the technical staff under his command also gave strength, burning 313 furnaces in 23 days, a total of 1oo8 tons of iron, after inspection, the first-class products accounted for 73 percent, and the second-class products with sulfur content less than 0.02 percent accounted for 27 percent, all qualified!

At that time, the price of pig iron was about 2ooo yuan a ton.

A few technicians secretly calculated, raw materials do not need money, according to the price of fuel and related auxiliary materials, power, water costs, wages and related management costs, should not be more than 1,000 seven, and this is only trial production, if you expand a little more, change to an annual output of 100,000 tons, 30 million a year is no problem, very good, very interesting.

Another technician said excitedly: "Do you think, if you renovate the furnace body, you can directly reduce the high coke ratio."

But none of them expected that the little boss would cry and say to everyone that he had lost ...... I can't do it anymore. After the little boss said it one by one, everyone immediately understood that it was not the little boss crying poor, it was really a loss.

It has to do with their beneficiation process. They used a combined heavy-float process to remove sulphur, which in plain terms was to flush out a considerable part of the sulphur – which of course would be discharged directly into the river – and the environmental authorities would have been fined heavily.

This time, the people's anger is too great for anyone to cover it. Not to mention the pollution released by the air during their smelting.

This means that there is still room for the equipment of the seventies and eighties in remote places. But not this time.

At that time, the little boss smiled bitterly and said: "Don't offend the people in order to make money, let's disperse, and the country is about to ban a small factory like ours, and we can't cover it-"

Since then, Xu Zhiming has embarked on the road of working in the machining industry. Until he was transferred to the smelting department of the Hantang Group Industrial Company.

In the eyes of the people of Hantang Group, this method is a treasure! He can't even think of a technician who has never worked in the front line. Taiwan has the most pyrite! Pure sulfur is a rare thing in nature.

When technician Xu Zhiming wrote out the detailed process at that time, he did not use field investigations, and was immediately recognized by everyone.

We are all professionals, and our experiences may be different, but the basic common sense is there.

Technician Xu Zhiming looked at everyone's arguments with a smile and answered their inquiries from time to time.

At that time, Xu Zhiming technician was secretly happy on Longya Island, this crossing was really good, he was transferred to the smelting department, not to mention, his identity immediately changed from Master Xu to Xu Zhiming technician.

Now even if it's work, it's interesting for a group of people to talk about something professional, three meals a day, and drinks are as much as they can - he easily walked to the upright freezer, naturally pulled it open, and opened the third bottle of Coca-Cola, which he usually likes to drink the most, and only drinks one bottle a day, and has never been reluctant to buy it.

Technician Xu Zhiming put on a comfortable sitting position, ready to accept everyone's inquiries with Ming. At that moment, he was completely confident.

At that time, after the 150 cubic meters of blast furnace shell equipment was kicked out, the tonnage of equipment in the smelting department became more comfortable.

This, of course, is conducive to the construction of a thirty cubic meter blast furnace. Even the degree of construction is obviously faster than that of Director Sun De's contact sulfuric acid plant.

At that time, Director Sun De was still strange, and said, even if you build it, I can't provide pyrite slag on my side?

Fang Zhengguo, the minister of the smelting department, said, "My blast furnace has a good appetite, not only can I eat the waste you produce, but normal iron ore is better." The annual output of 15,000 tons is accurate.

Director Sun De said proudly: "It seems that the annual output of a European country in the eighteenth century was only a few thousand tons, right? ”

Minister Fang Zhengguo said: "I don't compare with them, it's better to be hundreds of times better than them!" ”

Director Sun De smiled and didn't speak at the time.

Director Li Ziqiang didn't go to Budai Town tonight, he held back in his office for a long time, and he also asked Director Jianguoan to polish it, and laid out the things about the wormhole - all kinds of comments on the Internet suddenly quieted down, as if everyone was in a long exam.

Can you go back?! That's a good thing-but--

Chairman Wu Dapeng looked at various forums on the Internet in the office, and there were no special remarks for the time being, knowing in his heart that these people were all thundered, and various reactions would have to wait a while before they could be fed back.

The board of directors cannot ignore public opinion, this is our own business.

Now is a rare leisure, Chairman Wu Dapeng stepped off the desk and sat on the bamboo chair. He took out a cigarette from the small box on the bamboo coffee table, put a pomp on the bamboo coffee table, and lit a fire. First took a sip of it, and now there is a bitter aroma of caramel in it, which tastes very good, except that it is still a little rushed.

Manager Merges is here.

Since he moved out of the city, the two have only communicated online—close to each other, but they haven't seen each other for a long time. Everyone is very busy these days.

"Haha, Manager Mei is here, a rare rare guest - please sit, please sit."

After the two of them sat down, Chairman Wu Dapeng said: "Have some tea, or a hundred years of loneliness?" ”

"A hundred years of loneliness, I want the Zhang family to produce it-"

Now the 100-year-old lonely wine is divided into two categories, one is produced by the Liu family and the other is produced by the Zhang family. The style of the two is different.

The entrance produced by the Liu family is sharp, and all kinds of flavors go straight to the various taste buds of the tongue, giving people a feeling of killing, which is expressed in one word, which is cool!

After drinking, a residual fragrance remained in the mouth, and when the stamina came, the slightly drunken feeling made people excited and excited, like the pleasure of thinking about the lover of the first love.

The entrance of the Zhang family is softer, and when the wine rolls on the tongue several times, the bitter fragrance can really be released, but after swallowing, Wu Yongmei tried to add the musk flavor to it, and suddenly broke through the blockade of the bitter fragrance, and a cool fragrance was released.

After drinking, the mouth is full of fragrance, and after drinking too much, the stamina hits, making people's hearts flow with a faint sadness, like parting with a lover - it is suitable for a person to drink alone, and it is not suitable for a person to drink alone.

Of course, these are the comments made on the Internet by Sun Qiang, who claims to be drunk and not disorderly.

There are not many people who watch it, but as long as they read it, they all read it seriously and give comments seriously.

Unfortunately, this is only one of several batches. It never happened again.

Like cigarettes, everyone in the Han and Tang dynasties had rations. Sun Qiang didn't go to Gelanza City to make a special trip to the Internet, but to collect that batch of 100 years of loneliness, and I don't know what promises he made, anyway, he got a lot.

Chairman Wu Dapeng took down two ceramic bottles from the bookcase, one black and one white, with four big characters written on them: One Hundred Years of Solitude.

Chairman Wu Dapeng shook it, pulled off the cork vigorously, poured half a glass teacup for Manager Mei Lezhi with a black bottle, and poured it for himself with a white bottle.

"Ice or juice?"

Manager Merges said seriously: "Thank you, I always drink the original flavor." ”

Chairman Wu Dapeng did not persuade him, he walked to a small wooden barrel, used a clamp to take out a few pieces of ice from it, and put it in his cup.

The small wooden barrel was made of diatomaceous earth and sawdust and cotton, and the ice cubes were fine for a day or two.

The 6-base cold storage was completed as planned, and everyone had a certain amount of ice supply.

Chairman Wu Dapeng shook the teacup gently, raised his glass and signaled to Manager Mei Lezhi, and then took a big sip, ah, the mint flavor is very full, killing it, cool!

Manager Merle Zhi took a sip and experienced the taste of the wine, and it also felt good.

Chairman Wu Dapeng said: "You are here for the Guangzhou incident, right? What do you think? ”

"I'm not here for the Guangzhou incident, I'm just talking to you face-to-face about the arrangements for those women. If you ask me what I think about the Canton incident, I just want to say that now is not the time -- and I guess the board will decide that way. Otherwise, there would not be a sudden news that I could travel back in time at this delicate moment-"

Chairman Wu Dapeng smiled and was noncommittal.

"Then how do you comment on the behavior of Guangzhou?"

"In my opinion, the most prosperous period of Chinese culture was the Spring and Autumn Period and the Warring States Period, especially during the period of peace from the Jin and Chu Dynasty to the Three Kingdoms. According to the point of view of information theory, the amount of information is undoubtedly huge, and this is a dynamic world.

Since then, the diversity of thought has been declining.

After entering the Warring States period, the reform around the military was dominant, and the Legalists were dominant.

The Han Dynasty was established, Taoism and Confucianism led the way, and diversity almost disappeared.

At this time, we can see that the choice of ideology and culture of the nation on Ming University 6 is judged by its utilitarian role.

In fact, if we examine what Confucius did, we will find that he himself did not abide by the creed he preached.

Therefore, this nation will inevitably take up the two weapons of natural morality and actual morality against others -- of course, which weapon will be used will still have to come from reality, so that the first honesty is an inevitability, and the second breach of trust is also an inevitability -- there is no need to linger on it. As for the question of why this nation worships the lowly personality that everyone discussed in the early stage, it must be that the cultural core of 'utilitarianism' is at work. ”

Chairman Wu Dapeng smiled and said: "Then can you put your rational remarks on the Internet?"

Manager Mei Lezhi thought about it, smiled, and said, "We'll talk about this later, let's talk about the arrangement of those women first." ”

Wu Dapeng thought to himself, this is a kind old fox.

After the camp completed the disinfection task, Hantang Group made the following arrangements for this batch of women:

Women in their twenties and forties were assigned to the Akachi Agricultural Base and the Estuary Base, both of which required female labor.

For girls between the ages of 10 and 20, a closed camp was specially built, which was trained by the girls in the Hantang Group on a full-time basis, in the hope that they could take on the ability to provide services for the people of the Hantang Group within one to two years. It belongs to the Daming version of Lanxiang School, but the students are all women.

Those little Zhengtai were all sent to Chiji Primary School, and all Liu Haiyang's flight team was transferred to teach - Liu Haiyang also said aggrievedly: "The war with the Dutch has not yet begun, we disbanded the flight team and went to be an elementary school teacher, this is self-destructing the Great Wall!" ”

At that time, Chairman Wu Dapeng said: "At sea, do you have a good radar? ”

Liu Haiyang and his teammates immediately went to work as elementary school teachers speechlessly.

Originally, this was arranged happily, but the people of the Hantang Group seemed to forget that all the women in it were forced to come! They still have relatives in the Guangzhou area.

Some girls who learned the truth in the camp took the matter online. But the men of the Hantang Group didn't seem to see it - no one posted back, just the girls talking about it.

In the end, the girls collectively kicked the ball to Chairman Wu Dapeng, what do you say? !

After soliciting the opinions of several of his directors, he said: "It's just temporarily arranged here, and their relatives will be arranged here at that time, so that their families can be reunited together?" And then -- when the time comes, they will work for us for a few years, and all the tuition and living expenses will be paid. ”

The girls thought, yes, when the time comes, your family may be eager to come. We're doing a good thing, too.

Men think, after a few years of work, you little women are not in our hands - you know.
