Anti-Japanese War: Developing on my own, I brought back a US-equipped division

Su Zheng was so excited... No reward could compare to getting two iron mines.

The system's voice came again: "Warm reminder: The two iron ores rewarded by the system this time are hematite and magnetite. They are of high grade, few impurities, good reducibility, and average thermal strength. They can be used to refine iron very well."

As a time traveler, Su Zheng has some knowledge about iron ore.

磁铁矿213的主要成分是Fe3O4，即四氧化三铁，每个Fe3O4分子中有两个+3价的铁原子和1一个+2价的铁原子，即Fe2O3-FeO，氧原子为-2价，其中Fe的质量分数约为72.**%。

Generally speaking, hematite is an isometric crystal system. Single crystals are often octahedrons and less often rhombic dodecahedrons. Aggregates are mostly dense blocks and granules. The color is iron black, the streak is black, it has a semi-metallic luster, is opaque, has a hardness of 5.5 to 6.5, a specific gravity of 4.9 to 5.2, and has a certain degree of strong magnetism.

The main component of hematite is Fe2O3, which is iron oxide.

目前自然界中Fe2O3主要是两种，即α-Fe2O3和γ-Fe2O3，其中Fe的质量分数约为69.**%。

α-Fe2O3 is stable under natural conditions and is called hematite.

γ-Fe2O3 is unstable under natural conditions and is in a metastable state, which is called hematite.

Hematite is generally a trigonal crystal system, and good crystals are rare. Crystalline hematite is steel gray and cryptocrystalline; earthy hematite is red, with streaks of cherry red or fresh liver color, and has a metallic to semi-metallic luster. Sometimes the luster is dull, and the hardness is 5 to 6. The specific gravity is 5 to 5.3.

　(becc) It can be said that hematite is one of the most widely distributed iron minerals in nature.

According to the system's prompt, the two iron mines rewarded this time are both high-grade hematite and magnetite with few impurities... This can be used to refine large amounts of iron and provide raw materials for the Tiger Guards Arsenal.

As long as the raw material problem of the arsenal is solved, there will be no problem in equipping the entire Tiger Guard Regiment with American equipment.

By then, the combat effectiveness will definitely be off the charts.

So the top priority now is to develop the two iron mines.

Su Zheng immediately picked up the phone on the desk and said, "Connect me to the logistics department immediately and ask Chen Yi or Xiao Ya to answer the phone!"

After a while......

The call was connected.

The voice coming from the other end of the phone was Xiao Ya's: "Hello, this is Xiao Ya!"

Su Zheng: "Xiao Ya, you and Chen Yi come to the regiment headquarters now, I have something to discuss with you!"

Xiao Ya and Chen Yi were both stunned: "This... Didn't we just leave the regiment not long ago? Why do we have to go back to the regiment again?"

PS: Fourth update, now I need 3 more auto-subscriptions to break 60, please auto-subscribe, thank you!! .

Chapter 717: The whole regiment is equipped with American equipment! Full speed development (first update, please subscribe)

Although Chen Yi and Xiao Ya were puzzled as to why Su Zheng was so anxious to find them, they still said, "Okay, we'll go right over!"

After saying that, he hung up the phone and rushed to the Tiger Guard Regiment headquarters.

Headquarters of the Tiger Guards Regiment.

Xiao Ya and Chen Yi came to the regiment headquarters. When they saw Su Zheng, they asked with a puzzled look on their faces: "Captain...what's the matter? Why are you so anxious~?"

Chen Yi also said: "Yes, we just left the regiment headquarters, and you were so anxious to find us back. -"

Su Zheng said with a smile on his face: "Of course it's a good thing!"

"I just got the latest news. We have iron mines in our Xinzhongcun base, and there are two iron mines!"

Two iron ore mines?

Upon hearing this, Chen Yi and Xiao Ya's eyes lit up instantly and they looked full of energy.

This... these are the two iron mines discovered?

If there really are two iron mines, then it means that the raw material problem of the arsenal can be solved.

This is absolutely great news.

Xiao Ya: "Captain? Really? Did you really find an iron ore?"

"Is there really an iron mine in the Xinzhongcun base? We have been searching for it for such a long time, but we haven't found any. Now you have found it?"

The most scarce material in the arsenal is iron...which is also the most used raw material in making weapons!

Therefore, Su Zheng and the Huben Regiment also organized talents and experts to search for iron ore in the Xinzhongcun base and around the Xinzhongcun base.

However, nothing was achieved.

But now Su Zheng told them that there were iron mines in the Xinzhongcun base... and two of them.

This is absolutely great news.

Su Zheng: "Of course...So I asked you to come here so that you can organize and be responsible for the mining of the iron ore!"

Chen Yi: "If there really is an iron mine... that would be great. Our arsenal's raw material problem can finally be solved! We can mass-produce advanced weapons and equipment!"

"I really didn't expect that there is an iron mine in our Xinzhongcun base. Our Xinzhongcun base is really a treasure trove!"

Xiao Ya: "That's right...the lack of raw materials in the arsenal has restricted our development. Now there are finally no restrictions!"

· ····Request flowers·· ··

Su Zheng looked at Chen Yi and Xiao Ya and said, "Yes, that's why I asked you to come here immediately to start mining and refining iron ore, so as to increase the production capacity of our arsenal as soon as possible, so as to realize the upgrading of our Tiger Guards' weapons."

Chen Yi: "Okay, I promise to complete the task!"

Xiao Ya: "Then mining and refining the iron ore is the primary task of our logistics department... We must mine the iron ore as soon as possible within seven days, so as to carry out the relevant refining work!"

.. . ...

The mining and refining of iron ore are actually not complicated.

It is much easier than mining gold or oil.

Su Zheng: “Okay!”

Afterwards, Su Zheng told Xiao Ya and Chen Yi the specific location of the iron mine, and then arranged for them to carry out related work.

If the situation continues to develop in this way, it is estimated that it will not be long before the 100,000-strong Tiger Guards can be equipped with American equipment, and their combat effectiveness will definitely be improved to a higher level...

Chapter 718: The boss's shock: American troops (Second update, please subscribe)

After Chen Yi and Xiao Ya learned about the existence of the iron mine from Su Zheng, they immediately organized experts and talents to explore and mine the iron mine after leaving the regiment headquarters.

Because Su Zheng had already told Chen Yi and Xiao Ya the specific location of the iron mine, it was very easy for them to find the mine.

After experts and professional personnel surveyed and investigated the mine, it was finally decided to use open-pit mining to mine the "213".

There are two main ways to develop iron ore: open-pit mining and underground mining. Underground mining is further divided into flat mines, inclined shafts, vertical shafts, etc.

Because it's a mine.

The entire hill is full of iron ore, so the mining method is naturally mainly open-pit mining.

Open-pit mining, also known as open-pit mining, is the process of removing the covering on the ore body to obtain the desired minerals, and the process of extracting useful minerals from an open surface mining site.

Generally speaking, open-pit mining operations mainly include processes such as drilling, blasting, mining, transportation and soil discharge.

Compared with underground mining, the advantages of open-pit mining are full resource utilization, low depletion rate, suitability for large-scale machinery construction, fast mine construction, large output, high labor productivity, low cost, good working conditions, safe production, etc.

Moreover, the development of mines is simple and crude, basically using rock explosives, ammonium oil explosives, ammonium nitrate explosives, emulsion oil explosives, etc. for blasting.

The thing the Tiger Guards had the most was explosives.

It is also very suitable for open-pit mining.

Because the iron ore mine is a gentle ore deposit, it was decided to use the dump mining method for mining.

The heap mining method is suitable for gentle deposits with a dip angle generally less than 12, and uses an intermittent mining process.

Because the intermittent mining process is applicable to various geological and mineral conditions and has high labor efficiency.

In short, after consideration by experts, it is necessary to mine iron ore as quickly as possible, then refine it, quickly form iron materials, and then use them accordingly.

The Tiger Guards Arsenal is now in great shortage of raw materials.

Chen Yi and Xiao Ya also acted quickly. After confirming everything, they immediately started mining.

three days later.

Rumble...

Boom boom boom...

With the sound of explosions, the mining of iron ore officially began. ....

The raw material problem of the Tiger Guards Arsenal was finally solved to a certain extent.

After the iron mine is mined, it is immediately refined... All the refined iron materials will be transported to the Tiger Guards Arsenal for production work.

With the raw materials, the Tiger Guards Arsenal began to produce weapons rapidly.

Su Zheng breathed a sigh of relief when the mining and refining of the iron ore were on track.

Everything is on the right track, and the development of the Tiger Guards is also greatly guaranteed. From now on, it will not be a big problem for the entire regiment to equip itself with M1 Garand rifles 2.2.

this day.

Su Zheng arrived at the Eighth Route Army headquarters.

The leaders of the Eighth Route Army headquarters were even more shocked when they learned that the Xinzhongcun base had two iron mines and that Su Zheng was planning to build American-style equipment for an army of 100,000.

Chapter 719: The General Manager and the Deputy Chief of Staff were shocked: The terrifying combat power of the Tiger Guards (rd update, please subscribe)

Eighth Route Army Headquarters.

When the boss saw Su Zheng coming, he greeted him with a slight smile and said, "Su Zheng...you are here...sit down!"

Su Zheng sat down.

The Deputy Chief of General Staff also came over and sat down.

Su Zheng looked at the CEO and the Deputy Chief of Staff and said, "CEO, Deputy Chief of Staff, what do you want to talk to me about?"

The boss answered the question irrelevantly and said, "Su Zheng, your Xinzhongcun base has been developing in full swing recently."

"I heard that two iron mines were discovered in Xinmai Mountain, the back mountain of the Xinzhong Village base?"

The 14th Division of the Eighth Route Army is now located in the Xinzhongcun base.

Therefore, the discovery of two iron mines in the Xinzhongcun base... This is not a secret, and it is normal for the boss to know it.

The deputy chief of staff looked at Su Zheng with a smile and said, "Su Zheng, the Xinzhongcun base you chose is really a treasure trove of outstanding people and beautiful scenery!"

"In this small Xinzhong Village base, there are not only gold mines, oil fields, copper mines... but also iron mines. It is really quite rich. The local tycoons are really rich."

The Xinzhongcun base does have a lot of resources.

It can be said that resources are abundant.

Su Zheng didn't know whether these resources were rewards from the system or had always been there.

But none of this matters anymore.

The important thing is to ensure the rapid development of the Tiger Guards.

Su Zheng: "Boss, Deputy Chief of Staff, you are joking... I am just lucky!"

"You also know that our Tiger Guards Arsenal has always been short of raw materials, so our arsenal's production capacity is not high, and we don't produce many weapons and equipment."

"If we discover two gold mines in the Xinzhong Village base this time, it will solve our raw material problem to a great extent!"

"According to my idea and estimate, if the raw materials can be supplied, the arsenal can produce M1 Garand rifles, Gatling machine guns, howitzers and other weapons, shells, bullets, etc. at a high speed!"

"That is to say...by then our entire Tiger Guards will be able to equip themselves with advanced weapons and equipment!"

The deputy chief of staff looked at the boss, smiled slightly, and said, "Su Zheng, I remember you said before that you wanted to develop the Tiger Guards into a 100,000-man army."

"Now according to what you said... doesn't that mean your 100,000-man army will be equipped with advanced American equipment and weapons?"

Su Zheng nodded and said, "Yes...that's what I thought."

Hiss hiss hiss...

Hearing Su Zheng's words, the CEO and the deputy chief of general staff both gasped, looking surprised and shocked.

This... 213... one hundred thousand well-equipped troops?
