Chapter 99 The corner of the world

"Director Chen, what is your requirement for the purity of quartz sand?" Yang Dongsheng said suddenly.

"Alumina content is less than 2%, and iron oxide is less than 0.1%..." Director Chen casually reported a series of figures.

Director Chen introduced, and Yang Dongsheng began to adjust.

First transfer the iron ore on the side of the mountain to No. 5 ore and No. 6 ore, then gather the remaining iron and chromium to the bottom of the mine, and enrich the silica to the upper part.

After some adjustments, the chromium content of the quartz sand has been an order of magnitude lower than that required by Director Chen, and the iron content has also dropped to around 0.09%.

Although this data has met the requirements of the factory director, Yang Dongsheng has seen the production process of the quartz placer and feels that it is still not safe.

The mining tools used in quartz placer are iron drills, shovels, and hammers, and the transportation also depends on tractors. It is easy to add iron during mining and transportation.

And based on Yang Dongsheng's experience, if the purity of the silica is adjusted too high, it will definitely crystallize, and then the entire quartz placer will become a whole piece of silica, and it will be difficult to dig.

"What else do you need to make glass besides silica?"

"Huh?" Director Chen was taken aback.

"What is the raw material for your glass production? You can't use quartz sand all the time, right?"

Only then did Director Chen come to his senses. Although he didn't understand what Yang Dongsheng meant, he still opened his mouth and reported a series of numbers, "To produce 1 ton of flat glass, we need to consume about 800 kilograms of quartz sand, about 130 kilograms of soda ash, and 130 kilograms of There are about 1.1 tons of limestone, and some clarifiers, fluxes, and decolorizers are also needed. The main raw materials plus various auxiliary materials are about [-] tons.”

"Soda ash is sodium carbonate, and limestone is calcium carbonate, right?"

"Yes!" Director Chen nodded.

Yang Dongsheng looked around and found no soda ash, but limestone was everywhere.

Some limestone was mixed into the mine, but the iron content did not decrease much.

Yang Dongsheng took a look and understood that Shunhe iron mine is rich in resources. Almost all stones contain trace amounts of iron. The iron content of quartz placer is already very low, and it is not easy to reduce it.

"What do you mean by flux and decolorizer?"

"The decolorizing agent is manganese dioxide. Manganese dioxide can act with iron oxide to decolorize glass. In addition, sometimes part of magnesium can also replace calcium. Magnesium can improve the defect of glass devitrification tendency." Director Chen is skilled in business, and various The knowledge is clear in the chest.

Manganese dioxide Yang Dongsheng didn't find it, but as for magnesium, he seemed to remember seeing magnesium carbonate when he was in the Shunhe Coal Mine. At that time, he thought it was useless.

Shunhe Coal Mine has magnesium carbonate, calcium carbonate, calcium magnesium carbonate.

Probably due to the blocking of coal seams, their iron content is lower than that of quartz placer.

Yang Dongsheng mixed some magnesium carbonate, calcium carbonate, and calcium magnesium carbonate into the quartz placer, and the iron content finally dropped below 0.07%.

Seeing that Yang Dongsheng had finished talking with the glass factory, Mine Manager Liu of the Quartz Placer Mine hurried over to express his loyalty. He had already communicated with Mine Manager Wang of the Shunhe Coal Mine and offered to send people to mines 5 and 6 to study, and to implement the " Do more, get more; do less, get less" principle.

"Boom!" There was a loud noise.

A cloud of smoke rose from the entire mountain, and Yang Dongsheng felt his feet trembling.

It has to be said that the blasting of the quarry is much more shocking than the coal mine. If the coal mine was exploded like this, the working surface would have collapsed long ago.

After the blasting, the large stones were directly loaded onto tractors and transported away, while the smaller ones were loaded onto flatbed trucks and transported to the other side of the mine.

The mine manager Zhang of the quarry then introduced to Yang Dongsheng, "Mr. Yang! Our quarry produces two kinds of stones, one is large stones, they use them to build houses and lay foundations, and the small ones are used to make cement slurry The aggregate of..."

Yang Dongsheng interrupted him directly, "How many times are big stones more expensive than aggregates?"

"It's hard to say. Generally, it can be two to three times more expensive. If the material is good and the size is right, someone buys carved stone tables, stone benches, and stone lions, which can be four or five times more expensive. In the next step, we must implement good work." many……"

Yang Dongsheng interrupted him again, "Haven't you thought about reducing the amount of explosives and increasing the proportion of large stones?"

"In that case, the workload will be heavy, and the stones that can be produced in a day will be less." Mine manager Zhang frowned suddenly, fearing that this kind of ignorance would make him order blindly.

"If the workload is heavy, the wages will be increased, and the production of stones will be reduced, but the stones are expensive to buy, and you will only earn more. You can save costs by using less explosives."

"Then...how much less is appropriate?"

"Let the workers decide for themselves! They are on the production line, have more experience than you, and know the situation better than you!"

"How much wages will be added to the workers that day?" Mine Manager Zhang hesitated and asked.

"You asked me to make a decision? Can I be the mine manager for you again..."

Mine manager Zhang lowered his head and was sprayed with saliva by Yang Dongsheng, and he didn't even dare to breathe.

"Hey!" Yang Dongsheng sighed. It seems that the mine manager Zhang didn't mean to make him difficult. , Figure out a data and report it to me!"

"Okay, okay!" Mine manager Zhang seemed to come back to life.

The two walked while talking, and they reached the back mountain without knowing it.

"Mr. Yang, it's dirty over there, let's not go there!"

Yang Dongsheng glared at Mine Manager Zhang. Today he is here to see the situation. He must see every part of the quarry and get a thorough understanding of the production process.

"Why, is there anything shameful about this mine?"

"No, no!" Mine manager Zhang quickly waved his hand.

The two continued to walk forward. As soon as they turned around the foot of the mountain, Yang Dongsheng was shocked by the scene behind him.

I saw the workers unloading the relatively broken stones, and immediately a group of people came over and smashed the stones into small pieces with a sledgehammer.

After this group of people smashed it once, another group of people came over immediately, took the stone away, and smashed the stone into smaller pieces with a small hammer.

On the other side, there are more than a dozen sieves made of barbed wire. Stones that cannot pass through the sieve will be taken back and continue to be smashed.

Yang Dongsheng thought he had seen the scene of labor. During the busy farming season, he cut wheat and transplanted rice seedlings under the sun, and his skin was burnt. He had done this kind of work before.

After graduating from university, I went to the front line for internship.

Yang Dongsheng went down the well, burned coal, carried cement, paved the floor, picked up garbage... When he went up the well, he wiped like a ghost.

But Yang Dongsheng was still stunned by the sight in front of him.

Because most of those wielding small hammers to smash stones are women and children.

Hundreds and thousands of people smashed and sifted stones together, causing stone dust to fly on the scene.

After a long time, a thick layer of dust fell on the person's body, which looked like a stone sculpture at first glance.

Especially children, they are like little natives.

Yang Dongsheng never thought that there is such a corner in the world!
