The first blasting test looked successful, Xin Qiji was happy in his heart, and took a piece of ore with a golden luster handed over by Wang Linshan, even a layman could see that the grade of the ore should be very high, most of it was green, and the particles with golden luster should be natural copper.

Xin Qiji put this ore in his hand and rubbed it for a while, and his heart said that it would be good if he could achieve such an effect every time he blasted.

Xin Qiji saw that Li Ziyong was looking around for ores, and there were already a bunch of them in his arms at this time, so he smiled:

"Ziyong, what do you think of the grade of these copper ores?"

Li Ziyong poured the ore in his arms to the ground, then picked up two pieces and said:

"The left hand is of high grade, and the right hand is a little worse, but it is passable.

"Oh, that's good!"

The evaluation of the ore comes from the mouth of Li Ziyong, who has been immersed in this way for many years, and Xin Qiji has more bottom. But it's not yet time for blind optimism, so I turned around and said:

"This time the blast, the luck is good, but I don't know if every blast can have such good luck. Wang Linshan, has the other hole been dug as well? Once you've dug it, blast it again and see how it goes. ”

In addition to doubting whether any place in the underground can mine high-grade copper ore, Xin Qiji also has another question, that is, whether every blasting can achieve such a huge blasting effect.

"Lord Bao Xin, that pit over there, oh, that hole has also been completed, just let Brother Fu blast it again."

A hundred paces away was another cave, and when Fugui saw that this hole seemed to be deeper, Fugui filled another large bag of gunpowder that had been prepared into the bottom of the cave again, and after the filling was pressed, it detonated again. Similarly, a huge explosion of landslides and earth cracks was followed by a large crater seven or eight feet deep and three or four feet in circumference.

"Lord Xin, this time the luck is still very good, Lord Xin, you see, these copper ores are good!" Wang Linshan held several stones with golden light and patina in his hands, and looked at his happy appearance, as if he had picked up a treasure.

"Ziyong, what do you see?" , Xin Qiji is also very happy, but it is still necessary to ask the opinions of professionals.

Li Ziyong took a look at these copper ores, and even used a magnifying glass, and after reading them, he nodded:

"Lord Xin, the ore grade is good, and the ore produced by a blast is also considerable, which is many times stronger than human mining. With this blasting method, copper ore, which was previously difficult to mine, no longer has to worry about not being able to mine. ”

In recent decades, there have been few people mining ore, but more of it is collecting bile water seeping from the rock during the rainy season to smelt copper.

The cost of bile water copper smelting is low, but the disadvantage is to consume a large amount of iron, and the purity of bile water copper smelting is relatively low, and the bile copper contains iron, and it is difficult to remove the iron in it, which is also a way to do it. After all, the price of iron is much lower than that of copper, and the purity of copper coins cast in the Great Song Dynasty is not so particular, so in recent decades, bile copper has become popular.

In view of the huge demand for pig iron in Mao Geng, the demand for iron in the Special Economic Zone is like a bottomless pit, which is still the premise of Mao Geng's control of iron use, if Zhao Luan's idea is to build a real iron ship, or to use steel and concrete for construction, the demand for iron in the Special Economic Zone is even more astronomical. Therefore, Zhao Lu wrote to the imperial court and requested the suspension of copper smelting by the bile copper method. In addition, the bile copper method cannot be compared with the fire copper method in terms of purity, while Mao Geng has high requirements for the purity of copper materials. With these two points, the bile copper method had to be temporarily abandoned, and for a considerable period of time, copper smelting had only one option - using the fire copper method to smelt copper.

For pyrometallurgical copper smelting, being able to mine a good-grade copper ore means half the battle.

Wang Linshan thought that he also had a share of credit, and he was proud in his heart, so he took over and said:

"According to such a blasting method, according to the last general, oh, according to the lower officials, I am afraid that there will be no shortage of ore mined in a day, if 10,000 people come to mine, 3,000 people dig gunpowder pits, 10,000 people beneficiate, transport earth and stone, and then there are two or three thousand people to smelt copper, I am afraid that there will be more than 20,000 catties of copper in a day."

Xin Qiji thought about it, what Wang Linshan said seemed to be very reasonable, it was assumed that 20,000 catties of copper were smelted a day, but now it seems that if the method of multi-pit blasting is adopted, maybe it is possible to smelt 30,000 catties of copper a day. Moreover, with this blasting method, it seems that there may not be so many people.

"According to what you say, it seems that fifteen thousand people are enough, and the imperial court sent us 20,000 people, which seems to be more, right?"

If you can reduce the number of personnel, it will not only be able to reduce the monthly payment, but also have the advantage of building fewer houses, because the Great Song Dynasty, whether it is the forbidden army or the van army, is responsible for building good housing for them, and Minmetals Holdings is no exception.

If there are 5,000 fewer people, there is more room for profit.

Fu Ziyun listened to Mr. Xin's words, and suddenly remembered the experience of the Special Administrative Region, so he interjected:

"Mr. Xin, in fact, the men's female dependents can also be hired to do work, such as mineral processing, and some work that does not require too much effort, you can hire female dependents to do it, and the female dependents have a monthly salary, and the family's income is a lot more, according to the practice of the Special Economic Zone, the monthly salary of the female dependents is one-third lower, the company is cost-effective, and the female dependents are also cost-effective."

Fugui saw that Fu Ziyun was talking about the experience of the Special Economic Zone, and Fugui was not very old and could not hide his words, so he immediately added:

"Yes, it should be possible to hire one or two thousand female dependents, but when it comes to being careful, I am afraid that the female dependents are even better. For example, it is good for a woman to go to the cafeteria. ”

"The cafeteria?" , Wang Linshan didn't understand.

"Oh, that's right, over there in the SAR, we all eat three meals. At noon, they are all eaten in the canteen, so that every household can cook at noon, so that the ladies can free up their hands to work. Mr. Mao said that those who work should eat three meals, no, in fact, everyone should eat three meals. ”

Xin Qiji reads the newspaper diligently, and knows well that Mao Geng advocates the three-meal system, in fact, Xin Qiji's family has already had three meals a day. For the unified dining in the canteen, it is the same as the unified meal in wartime, and of course it has great advantages in saving manpower.

"In this way, the female dependents can also do some light work, and they really don't necessarily need 20,000 troops." , Li Ziyong has seen the power of blasting mining today, if he lets his female dependents also work, he is afraid that fifteen or six thousand people will be enough.

However, after all, it has not been rolled out yet, and I don't know if there is really no need for 20,000 people, in case one person is not enough!

"I think fifteen thousand people are enough!" , Wang Linshan just spoke according to his own thoughts.

"No, 20,000 people. Even if there are more people smelting copper, we still have to smelt zinc, zinc is a treasure! The more the merrier, I think it's more profitable than copper. ”

Xin Qiji's sprout at this moment, "General Han Xin." The more, the merrier". The resources of the Xiang army assigned to him by the imperial court, Xin Qijian will be pushed out lightly.

Now Xin Qiji let his disciples Fan Kai and Yuan Fu lead a group of reliable mining and metallurgical craftsmen to build zinc smelting furnaces on a large scale, and after the zinc smelting here is normal, you can open a number of branches in other lead and zinc mines, didn't Mao Geng say, where there is lead ore, there is zinc ore!

Fugui listened to Xin Qiji's words, and glanced at Fu Ziyun again, Fu Ziyun understood, and said:

"Mr. Xin, if there are many people, in fact, Mr. Mao also said that you can go to mine manganese ore, manganese, next to the gold word, on the right is the manganese word of Confucius and Meng. We also brought a sample of manganese ore this time, which is a black stone, and after mining manganese ore, you can smelt iron manganese ---iron manganese ---"

"Iron-manganese alloy." , the homing interface.

"That's right! Iron-manganese alloys. According to Mr. Mao, this iron-manganese alloy is a rare good thing. ”

Xin Qi said in his heart, Mao Geng is providing himself with a new treasure, and immediately asked:

"This manganese ore, Mr. Mao must know where it is, right?"

"Yes, according to Mr. Mao, there is Tanzhou on Jinghu South Road, just walk seventy or eighty miles upstream along the Xiangjiang River in Changsha, as long as the wind is released, let the people go to find black stones, they will definitely be able to find them."

Xin Qiji was very excited when he heard this, he was handsome on Jinghu South Road in the past, and he also served as the prefect of Tanzhou, if there is manganese ore in Tanzhou, it is not a piece of cake to move the people to find it!

"Maote is going to be long, so don't worry! It just so happens that there will be an army in Tanzhou that will be transferred to Minmetals, so let them go and find what kind of manganese ore to see if they can dig up treasures. ”
